The genus Zantedeschia is restricted to
the African continent consist of seven species.
Zantedeschia fall into two main types: hardier
outdoor forms, often called Arum lilies,
with striking white flowers; and the more tender
forms, typically with white-spotted leaves and
pretty flowers in yellow, orange, pink or dark
purple. These are often called Calla lilies.
Zantedeschia
aethiopica
is native to Southern Africa where it grows in
marshy places. It
is
evergreen or deciduous depending on the habitat
and rainfall regime. In the Western Cape it is
dormant in summer and in the summer rainfall
areas it is dormant in winter. It will remain
evergreen in both areas if growing in marshy
conditions which remain wet all year around.
Zantedeschia
is named after Italian physician and botanist
Professor Giovanni Zantedeschi.
The species epithet
''aethiopica”refers to
the fact that it is native to Africa.
Although commonly known as the arum lily or
calla lily, it is not a lily but an aroid.
The Arum Lily is well known for its
striking appearance when in flower, with a
brilliant white floral bract wrapping around a
yellow finger-like projection in the centre. The
flowering parts arise from a ring of glossy
green leaves. The fruits are green berries turn
orange at the base when ripe.
The flowers of Zantedeschia aethiopica
are faintly scented and this attracts various
crawling insects and bees which help for
pollinating the flowers.
Arum
Lily
is
very popular as cut flowers and as an
ornamental. It is used as a symbol of purity in
bridal and funeral flower arrangements.
The leaves and rhizomes of Arum Lily are
traditionally used in dressings and oral
preparations for a variety of complaints in
southern Africa. The rhizomes are edible,
although the plant is reportedly toxic.
Traditionally the plant
is boiled and eaten. Raw plant material causes
swelling of the throat because of microscopic,
sharp calcium oxalate crystals. The leaves are
also traditionally used as a poultice and a
treatment for headaches.
Scientists have shown that
Zantedeschia aethiopica may be
useful in artificial wetland systems to clean
waste water and prevent algal growth.
Arum Lily
grows best in moist soil or shallow water.
Planting under shade is preferable if there is
no boggy position for this plant, but this will
reduce the number of flowers. Fertile soil is
required. In optimum conditions, a good display
of flowers may be enjoyed in the spring and
summer.
Zantedeschia
aethiopica
grows to 90 cm but may get taller in the shade.
It has dark green leaves with an arrow head
shape. The size varies according to the amount
of shade. The flowers appear in a main flush
from February to June, although there may be the
odd flower at other times of the year.
Arum Lily
forms large colonies in marshy areas ranging
from the coast to an altitude of 2250m. Thus one
will find them contending with humid, salt laden
air at the coast and freezing, misty mountain
grasslands at high altitudes. The leaves of the
arum are very interesting in that they contain
water stomata which can discharge excess water,
by a process known as "guttation". This prevents
water-logging and enables arum lilies to grow in
wet conditions.
Zantedeschia aethiopica
is easily cultivated by seed or division. Seed
should be sown in spring. The fleshy rootstock
can be divided when the plant is dormant, it
should be re-planted not less then 3 cm deep. It
may also be propagated by division where the
plant is not dormant.
Arum
Lily
may be used as a marginal plant along streams,
or on the edge of a pond. Plant in partial shade
if there is no permanent water. It may be
combined with Yellow Iris (Iris pseudocorus),
Golden Iris (Iris xantospuria) or Black
Iris (Iris lousiana ‘Black gammock’)
in marshy areas. It can be planted as a foliage
plant in deep shade under trees but will not
flower well in this position. Nowadays many
cultivars of Zantedeschia are available and can
be used as pot plants or at garden design. |

Philodendron
is a large
genus
of
flowering plants in the
Araceae
family, consisting of about
900 species. Compared to other genera of the family
Araceae,
philodendrons have an extremely diverse array of
growth methods. The habits of growth can be
epiphytic,
hemiepiphytic,
or rarely
terrestrially. Philodendrons
originate in tropical USA, the West Indies and South
America, and are popular for their foliage and
dramatically lobed leaves. Many are climbers, and do
well as indoor plants in brightly lit positions.
Philodendron
selloum
has been a mainstay in tropical landscapes and
indoor plantings, for long years. Actually
Philodendron selloum is a commonly used name
for Philodendron bipinnatifidum.
The plant is quite tropical looking, relatively
easy to grow and large. In fact, it grows very large
at maturity. For indoor decor and interiorscaping, a
smaller plant with somewhat the same look would be
ideal. Such a plant became available when
Philodendron xanadu
came into the market.
Xanadu combines many of the good
points of its relatives with some special qualities
of its own.
The spathe of
Philodendron xanadu
is dark violet-purple bordering on red and is
different from the spathe of Philodendron
bipinnatifidum which basically green with a
white interior (as seen at the photo).
Xanadu
is a member of a group of
Philodendron plants known as the
Meconostigma group. These plants are
also known as the "Tree Philodendrons" because they
develop a heavy stem that can be thought of as a
trunk, unlike other vining
Philodendron species.
Philodendron
xanadu
discovered in Western Australia in 1983 as a chance
seedling. It was subsequently patented as
Philodendron “Winterbourn”, then renamed Xanadu
by House Plants of Australia and released as
their plant of the year in 1988.
This plant, which was granted United States Plant
Patent in 1989. Now that the patent has expired,
plant is available for propagation to anyone who
wishes to without legal restraint.
Now it is known that,
Xanadu is a separete species rather
than a hybrid as previously believed.
Philodendron xanadu
is one of the exclusively cultured species in the
labs as a tissue cultured (cloned) specimen. Every year more than two million
plants are sold worldwide.
Philodendron
xanadu
is an evergreen low shrub with a compact, tidy
growth habit and attractive lobed leaves. It rarely
exceeds 90x90cm. Decorative small lobed leaves
compact growth low maintenance and pest free,
doesn't produce aerial roots as some other
represantative of the family.
Xanadu likes full sun to semi shade,
plenty of water in spring and summer, annual
fertilising with slow release fertiliser to keep it
green.
Use in landscape:
Philodendron xanadu can be grown in
the garden in tropical and subtropical climate areas
and also in warm temperate coastal areas. In the
colder parts of world it's best grown as an indoor
or patio plant under high light conditions planted
in drifts for a massed display good pot specimen in
semi shaded conditions great for tropical-look
gardens but blends with many different plants great
tidy plant around pools. |

Strelitzia reginae “Gold” is a rare yellow form
of the well-known crane flower, Strelitzia
reginae.
-Yellow-flowering strelitzias have been known for a
number of years. These plants
spontaneously
have cropped up in France, California, Australia,
Japan and in South Africa at a few locations, but
always as isolated specimens. The seeds from these
yellow forms will not breed true as they will most
likely have been pollinated by an orange plant. To
get yellow progeny, two yellow plants must be
crossed. At Kirstenbosch in the 1970's, there were
seven yellow plants in the nursery. John Winter, who
was curator during this period, began a project to
increase the stock. It took almost twenty years of
careful selection and hand-pollination, and in 1994
the original stock had been built up enough to
enable them to introduce the yellow strelitzia to
horticulture. It was released and traded under the
name “Kirstenbosch Gold” until 1996. Palmiye
Merkezi bought some seeds as soon as the seeds were
available in market. First Golden Strelitzia flower
was obtain at 1999 at Palmiye Merkezi in Türkiye.
NBI was granted permission to re-name it in honour
of Nelson Mandela as “Mandela’s Gold” at
1998.
Golden Bird of Paradise
is a stemless, evergreen clump-forming
perennial. Greyish green, banana-like leaves grow to
a height of about 150cm. Flowering season starts at
the end of autumn and continue during winter and
spring. Beatiful, large, bird-like flowers are held
above the foliage on the tips of long, robust stalks.
Plant divide to two after each flowering. In years
it makes a very large clan.
The hard, beak-like sheath from which the flower
emerges, is called the spathe. This is held at right
angles to the stem, and has the appearance of a
bird's head. Each spathe contains 4 to 6 flowers,
and these emerge one at a time from the spathe. Each
flower consists of 3 clear yellow sepals and 3
petals. The yellow sepals give the appearance of a
crest on the bird's' head. Two of the royal blue
petals are joined together around the stamens and
the style to form an arrow-like structure. The third
blue petal is shorter than others and stays on top
of them (please look at photo “çiçek yapısı”).
Strelitzia reginae “Gold” is an easy plant to
grow and will thrive in most soils. Full sun, rich
and well-drained loam soil with a pH of
approximately 7,5, regular deep watering in summer
and liberal applications of fertilizer in growing
season, necessary to make the ideal condition.
Plants will respond well to generous applications of
manure and compost or additional fertilizer watered
in about once a month during summer. A fertilizer
with the proportions 9-3-15 encourages flowering.
Strelitzias will also do well in semi-shade, in
sunny countries but they need as much sun as they
can get if they are to flower well.
Golden Bird of Paradise
once established, they can survive with very little
water, and they are tolerant of wind and coastal
conditions. It is sensitive to freze as the other
strelitzias and needs a sheltered position against
northern winds at mediterranean region in areas that
experience frost.
Use in Landscape:
Strelitzia reginae
“Gold”
is a striking feature plant, a decorative garden
subject and adds a tropical feel to courtyards and
swimming pool areas. They look marveleous in
separate groups with orange color strelitzias at the
grass areas. May be use as a borderline plant or as
first row in front of the Giant Strelitzias (Strelitzia
nicolai). It is suitable for cultivation in large
terracote pots and containers. In this case, for
better flowering performance it should be fed with a
dilute liquid fertilizer at least every other week,
particularly at the beginning of the growing season.
In cold climates it can be grown as a winter garden
plant or in nurseries. It is also make an excellent
cutflower.
Propagation of Golden Bird Of Paradise is by
seed or division. The plants are slow-growing and
large clumps that are split or moved will take at
least two years to re-establish themselves and
flower again. To get a mature flowering plant from
seed, under ideal conditions it takes about 3 years.
But for unexperienced growers, this time is not less
then 5-6 years. Before sowing, the bright orange
aril should be remowed. Seedlings should be a good
size before being transplanted (two to three leaves)
into a well-drained potting medium. Regular
repotting allows the young plant to develop rapidly.
Restricting the root development retards growth. |

Strelitziaceae Family is consist of 5 species, which
naturally grown in South Africa. These species are,
St.Regina, St.regina juncea, St.alba, St.caudata
and St.nicolai.
Natal Wild Banana
grows mostly in coastal dune vegetation and in
evergreen forests near the coast. It grows in the
Eastern Cape, KwaZulu-Natal at South Africa, and up
into Mozambique towards Zimbabwe.
The name
Strelitzia
was given to honour Queen Charlotte England (she was
from the family of Mecklenburg-Strelitz).
Nicolai
comes from, Grand duke
Nikolay Nikolayeviç,
son of Czar Nicholas I of Russia.
Strelitzia
nicolai
grows up to 10m high and
4m wide. It is an evergreen tree with multi-stems
that form dense clumps. Although not related to the
true bananas or the wild banana (Ensete
ventricosum), the leaves and growth habit of
Natal Wild Banana are somewhat similar and
probably account for the common name. The stem is
woody and smooth in texture. It is light to dark
grey in colour and marked with old leaf scars.
Attached to the stem by long, thick leaf stalks are
the enormous, opposite leaves that are shiny and
grey-green in colour. Leaf blades can reach up to
2m, these tear in the wind and come to resemble
giant feathers.
The
flower of
Strelitzia nicolai
is a typical crane-flower inflorescence, up to 50mm
long. The flowers of this tree have white sepals
with blue petals and consist of 5 purplish blue,
boat-shape sheaths. The whole flower resembles the
head of the bird, with a white crest and purple beak.
The tree flowers throughout the year with a peak in
spring-summer. The inflorescence have more than one
flower. The seeds are black in colour, with a tuft
of a bright orange woolly aril on the lobe. They are
produced mostly in autumn and some in spring.
Natal Wild Banana’s
leaf stalks are dried and used to make a rope for
building huts. The flowers provides nectar that
attracts sunbirds. Monkeys feed on the soft part of
the flowers as well as on the orange aril of the
seeds.
Propagation
is done from seeds, also it is possible to prapagate
this tree from root suckers. To grow from seed,
orange arils should be removed before sowing. Seeds
should be covered with 5-10mm layer of compost.
Seedlings should be kept in a shady spot for the
first season. Once planted out this plant is fast
growing. It will grow in semi-shade or full sun and
requires a moderate amount of water.
Strelitzia nicolai
is drought tolerant, but
it does not tolerate frost more than -40C,
so should be planted in a protected spot in
temperate climates. It withstands salty coastal
winds, making it a good feature plant or screen for
coastal gardens.
Use in Landscape:
Natal Wild Banana is an eye
catching evergreen, effective throughout the year
and is useful for creating a lush, tropical effect.
It can be used to softened hard landscaping,
buildings and pools. It also looks good contrasted
with evergreen lawns and shrubs. As the root system
is a bit aggressive, it should not to be planted too
close to paths and structures.
Strelitzia nicolai
can be used as an eye catching pot plant in cool
places or in small gardens, also it is a good choise
for winter gardens. |

Clivias
are endemic to southern Africa. Bush Lily
grows in dappled shade, often in large colonies. The
soil is well drained and humus rich.
Clivia
comes from, Lady
Charlotte Clive who first cultivated and flowered
the specimen in England, miniata comes from
minius (colour of
lead tetroxide)
referring to the flowers.
Cliviamania began in the
1800's when specimens were arrived to England from
Kwazulu-Natal. In Victorian times this beautiful
plant was very popular for indoor use in England and
Europe.
Part of the fascination
has been with the breeding of Clivia, both
between the four species (C. nobilis, C.
gardenii, C. caulescens, C. miniata) and between
forms and colours within the species. Breeders
select for specific traits in each generation which
produces pronounced qualities such as huge, broad
petalled flowers, red, yellow or apricot coloration,
broad leaves, fan shaped leaf arrangement,
variegation, dwarfism and many others.
Clivia miniata
is a clump forming perennial with dark green, strap
shaped leaves which arise from a fleshy underground
stem. The leaves can reach 45 cm height and 8 cm
wide. The flowering heads of brilliant orange (rarely
yellow), trumpet shaped, flowers appear mainly in
spring April to May but also sporadically at other
times of the year. The deep green shiny leaves make
a very nice contrast to the masses of orange flowers.
Bush Lily
can be propagated by seed or by removing suckers.
The fruits are bright orange when ripe (or golden in
the case of the yellow flowered plants).
Clivia
miniata
is easily cultivated and very rewarding. It should
be planted in dappled shade, (they are sensitive to
sunlight and will burn easily) in well composted
soil. This will also help with soil water retention
during dry periods. The plants should be watered
regularly during the summer months which is their
growing season. Watering can be reduced during
winter and the plants will tolerate fairly long dry
periods.
Bush Lily
is frost tender and may be damaged if in a position
that is exposed, to cold winds especially. It takes
a long time for the damage to grow out if this
happens, so it is best to select a sheltered site.
The roots are reportedly extremely toxic but are
used medicinally for various purposes.
Use in landscape:
Clivia miniata should use in shade and
protected areas in mild climates. Bush Lilies
are spectacular container subjects. They should be
grown in a well drained potting medium which has
plenty of compost added. |

Cotyledon
is belong to family of Crassulaceae. Cotyledon genus
of 10 species of compact, often clump-forming,
perennial succulents and evergren subshrubs from
desert or shaded areas in Southern Africa, East
Africa and the Arabian Peninsula. The stalked,
fleshy leaves are borne in opposite pairs. Tubular
to bell-shaped, generally pendent, red, yellow or
orange flowers are borne in crowded, terminal
panicles mostly in late summer and autumn. The genus
name Cotyledon comes from the Greek
word kotyledon that means cup-shaped, this
refers to the leaves of some species.
COTYLEDON ORBİCULATA
- PIG'S EAR
Cotyledon orbiculata
is a succulent plant has thick leaves which may vary
from green to grey, often with a red line around the
margin. Cotyledon orbiculata is
naturally found in Angola, Namibia and South Africa.
Plant may reach up to 100 cm height and and 50 cm
wide. The species name orbiculata
comes from the Latin word meaning round circle.
PIG'S
EAR
Flowering time is mostly late summer to autumn. The
colourful, hanging, tubular, bell-shaped flowers
1,5-2cm long are carried in clusters on the ends of
an elongated flower stalk up to 70 cm. They are
mostly orange-red, but yellow flowering forms are
also occasionally found. Mild frost will damage the
flowers, but the plant itself will tolerate moderate
frosts.
The brightly coloured flowers, attract bees and
birds. The silver-grey leaves of some forms owe much
of their attractive colouring to a powdery white
coating which may assist in reflecting much of the
sun's heat to prevent excessive water loss from the
thick succulent leaves.
Cotyledon orbiculata
is a well-known medicinal plant. The fleshy part of
the leaf is applied by many South Africans to soften
and remove hard corns and warts. The heated leaf is
used as a poultice for boils and other accessible
inflammations. Single leaf is eaten as a vermifuge
and that the warmed juice can be used as drops for
toothache or earache.
Use in Landscape:
PIG'S EAR is an ideal plant for the rockery,
but also grows well as a pot plant placed on a
veranda. It will also add texture and form to the
well-drained flower border. When planted as a pot
plant, good drainage is important. It is often found
in full sun, but also grows well in semi-shade under
trees. This is an ideal plant for the water-wise
gardener.
Cotyledon orbiculata
may be grown from seed, taking tip cuttings is the
fastest method of increasing plant numbers; they
must be kept fairly dry to prevent rotting. This
plant has few pests, but it may be attacked by
snails in the garden. |

Maclura
is a genus belong to Moraceae family, consist of 15
species. They are usually thorny, deciduous or
evergreen, dioecious trees, shrubs or climbers, the
branches often reduced to spins. Naturally found in
East Asia to Australia, and from South Central USA
to South America.
MACLURA POMİFERA
(Maclura aurantiaca) OSAGE ORANGE
Naturally found in South
Central USA. Maclura pomifera is one
of the most widely planted trees in North America,
especially on the plains, yet it has no commercial
value as timber, lumber or even pulpwood. Instead,
it was used to make high, thick, thorny, termite and
rot resistant hedgerows. It did such an admirable
job as hedging material.
Botanically, the
Maclura pomifera, was named for a
Scottish-born semi-American geologist named William
Maclure, pomifera means bearing
apples.
Bois d'arc and Bow
Wood are common names for Osage Orange
that hint back to the native American Indian's use
of the wood to make bows. (The Osage Nation
is a
Native American
Siouan-speaking
tribe in the United States that originated in the
Ohio River
valley in present-day Kentucky. After years of war
with invading
Iroquois,
the Osage migrated west of the
Mississippi River
to their historic lands in present-day
Arkansas,
Missouri,
Kansas,
and
Oklahoma
by the mid-17th century).
Maclura
pomifera
rounded,
deciduous tree, thorny when young, becoming less so
with age, with ovate, pointed, dark green leaves, to
10 cm long, turning yellow in autumn. Tiny cup
shaped, yellow-green flowers (the females in short
racemes, males in dence, spherical clusters) are
born in late spring or early summer, followed on
female trees by large, wrinkled, yellow-green fruit,
to 12 cm across.
Osage Orange
is a very frost resistant tree, can reach up to 15
metres high and 12 meters wide.
The trees will be either male or
female, and only the females will produce hedge
balls. The trees become sexually mature by age 10
and there is no easy way to determine the gender
prior to then. The trees can grow quickly in a good
location with ideal growing conditions.
Use
in landscape:
They make a decent shade tree within ten years.
Maclura pomifera often used to make a
natural and cheap hedgerow. To make a hedgerow, the
trees should be planted no more than 150 cm apart
and plan to thin them as they get bigger. Osage
Orange fruit is known alternately as "Hedge
Apple" and is inedible to almost every animal
except squirrels. The fruit is often used as a
natural insect repellent, especially for cockroaches
and crickets, as well as a dye.
Maclura pomifera
has been successfully used in strip mine reclamation.
Its ease of planting, tolerance of alkaline soil,
and resistance to drought are desirable qualities.
These qualities plus quick growth, long life, and
resistance to injury by ice, wind, insects, and
diseases make Maclura pomifera a
valued landscape plant. |

PORTULACARIA AFRA-PORKBUSH,
ELEPHANTS FOOD
Portulacaria afra
or Porkbush belongs to a large and widespread
family Portulacaceae which includes the
popular
Portulaca. Probably it is the only
member of the genus, but have some varieties. The
name
Portulacaria is composed of
Portulaca and
aria suggesting a similarity to the
genus
Portulaca.
The word
afra is indicate plant occurs in Africa.
Portulacaria afra
is a
succulent shrub, which
naturally grown in semi arid, rocky lowlands in
Namibia, South Africa, Swaziland and Mozambique. The
Porkbush is a popular succulent garden plant
in use around the warm climates of world and is
often used for bonsai.
Portulacaria
afra
is an attractive, evergreen succulent shrub or small
tree that can reach up to 500 cm in height in
natural sides. It is hardly reach to 200 cm. in
garden situation. It has small round succulent
leaves and red stems. Small star-shaped pink flowers
are borne en masse from late winter to spring
although flowering in pot cultivation is often
erratic. The Porkbush is easily propagated
from cuttings, the seed is not often available.
In the Addo National Park (South Africa) elephants
eat the Porkbush from the top downwards
allowing the plant to spread itself vegetatively by
spreading horizontal branches at ground level. The
leaves of the porkbush can be eaten and have a sour
or tart flavour. It is preffered meal for many
animals also by tortoises.
Traditional uses of Portulacaria afra
also include the increasing of breast milk by
lactating mothers. The leaves are used to quench
thirst, sucking a leaf is used to treat exhaustion,
dehydration and heat stroke. Crushed leaves can be
rubbed on blisters and corns on the feet to provide
relief. The leaves are chewed as a treatment for
sore throat and mouth infections while the
astringent juice is used for soothing ailments of
the skin such as pimples, rashes and insect stings.
The juice is also used as an antiseptic and as a
treatment for sunburn. The porkbush has also been
indicated as a soil binder for preventing soil
erosion.
Use in landscape:
Porkbush can be used as a screen or even a
clipped hedge. It also makes a handsome and hardy
Bonsai. It is used in full sun or semi-shade in dry
areas or even in well-watered flowerbeds at warm
climates. It can tolerate a moderate degree of frost,
when mature. If there is danger of frost, should be
kept as pot plant in nursery.
It has been shown to be effective in carbon
sequestration (binding atmospheric carbon which is
responsible for climate change), in semi-arid
landscapes and thicket vegetation it is also being
used for restoration purposes.
Portulacaria afra
Various different forms are found in cultivation, a
prostrate low growing ground cover, 'Prostrata'; a
shrubby form with small round leaves which turn an
attractive yellow in full sun, 'Aurea' and 'Foliis
variegatus' a slow growing variegated form which is
well suited to pot culture. Another variegated form
known as 'Medio-picta' has green leaves with whitish
markings spreading from the centre. A large-leaved
form known as ' Limpopo ' has much larger, more
ovate leaves that can measure up to 20 - 30mm long
and 15 - 20mm wide. |

The Syagrus genus occurs naturally in South
America and can be found from the north of Venezuela
and Colombia all the way down to the south of
Argentina and Brazil. It comprises 32 varieties of
palms with featherlike leaves. Some have one trunk,
some several and there are even trunkless
varieties. The name Syagrus comes from the
old Latin for ‘palm’.
SYAGRUS ROMANZOFFIANUM
– QUEEN PALM
(Cocos plumosa – Arecastrum romanzoffianum)
Palms
are known as the ‘queens’ of the plant world and
Syagrus romanzoffianum is the queen of
them all. This Queen Palm can be found in
the forests of Brazil, Paraguay, Uruguay, Bolivia
and northern Argentina. It has a straight, grey
trunk 20–40cm wide rising to a height of 15 metres,
and it has been known to reach 20 metres. It has
pinnate leaves and produces cream flowers followed
by clusters of fruit, 20–25mm long, which are
initially green then turn orange as they ripen.
These contain prodigious amounts of seed. The tree
is hermaphroditic and only one tree is needed to
produce seed. It gets the name ‘romanzoffianum’
from Nicholas Romanzoff, a Russian prince who
financed the plant hunting expedition which led to
its discovery.
Syagrus romanzoffianum
can stand hot sun and will also grow in shade. If
very well fertilised, its trunk will widen and its
leaves also become broader and greener. It grows
well inside high buildings in a position where it
gets much light. In general it prefers a slightly
acid soil, but it will eventually acclimatise in
other soils. In an alkaline environment, due to
lack of manganese, its leaves may seem looser and
may even look wavey.
The
Queen Palm is the palm most commonly planted
in Florida. For the past 20 years it has been
imported into Turkey where it was first reared from
seed at the Palm Centre. At the Centre in 2009 we
have obtained seeds from 15-year-old 6–7 metres in
height Syagrus romanzoffianum palms.
Despite the fact that the Queen Palm has
tropical origins it can withstand cold better than
you might think. At the Palm Centre it has been
exposed to cold down to -60C and, apart
from a slight yellowing on the edges of leaves, it
was not damaged in any other way.
In landscaping Syagrus romanzoffianum
can be used as a single, architectural plant which
gives an instant tropical flavour or it can be used
in groups, and works when planted around or between
high buildings, in parks and gardens, on broad
streets, by the side of a swimming pool or as edging
along paths.
Large Queen Palms give welcome shade and
always add an exotic note wherever they are
planted. From an architect’s point of view they are
ideal for delineating any open space and, as
previously stated, they work especially well when
planted between large buildings. |

Kalanchoe
is a genus that contain about 130 species of
succulents and has a very wide distribution area:
Saudi Arabia, Yemen, Tropical Africa to South Africa,
Madagascar, India, S. China, Phillipines, Malaysia,
Brazil and Australia. Kalanchoe is belong to
Crassulaceae family. The family name
Crassulaceae means thick fleshy leaves
which is characteristic of the plants in the family.
A number of species can
take temperature close to freezing for short times,
but none will really tolerate any frost. The species
that have pubescent leaves can generally tolerate
intense heat without trouble particularly if kept in
light shade. The species with smooth leaves are a
little less tolerant, but fare generally better than
most other crassulaceae in such hot conditions.

thyrsiflora refers to the inflorescence,
which is a thryse or many-flowered kind of
inflorescence. Contrarily to other members of the
family that have most flower parts in multiple of 5,
Kalanchoe flowers have 4 connected petals forming a
tube, 4 sepals, 4 carpels, and 8 stamens.
Flapjack
forms
a basal rosette of large, rounded, fleshy, stalkless
leaves, which are grayish-green with red margins,
covered with a white powdery bloom. Plants reach
about 60cm, erect, upward facing, tightly arranged
leaves are without petioles.
Kalanchoe thyrsiflora
is a monocarpic plant producing a stalk about 1m
tall, dying back after flowering. The inflorescence
is terminal and erect with densely clustered
panicles of greenish waxy flowers with yellow
recurved lobes. Small tubular flowers approximately
15mm long. Flowering from autumn to spring. On the
inflorescence the lower leaves are rounded and
become smaller as they ascend along the flowering
stem. The flowering may persist for a long time on
the plant until the whole plant eventually dies.
When given enough sunlight, the large and dramatic
sage-green leaves develop a bright red or pink band
that highlights the edges of the smooth, fleshy
paddles.
Flapjack
being a succulent perennial, it does not require
much attention in sunny dry gardens. Plants take
about 3-4 years to mature, but flowers may appear
from the second year and remain for another year
before seeds are dispersed.
In its natural habitat, plants are sometimes exposed
to harsh temperatures and have adapted to survive
over many years. Besides succulence, the plants
always erectly point their leaves upward toward the
sun in order to minimise the surface area that is
exposed to the sun. This helps the plant to conserve
moisture even more. The white floury coating on the
leaves and inflorescence helps to reflect the sun
away thus keeping the plant cool. Ants, bees and
other flying insects, which visit the flower at
midday, are responsible for pollinating
Kalenchoe. The fertilised flowers may
persist on the plants for a long time and the very
small seeds are effectively dispersed by the wind.
It is possible to grow
Kalanchoe thyrsiflora vegetatively
as well as sexually. For quick results leaf cuttings
can be made from mature plants. When making cuttings
it is important to ensure that a small piece of stem
is attached to the leaf. Make cuttings during the
warmer months. Place in coarse river sand in an area
with air movement and shade of about 40%.
Alternatively the seeds which are very fine can be
sown on a sandy medium then lightly covered.
Horticulturally
Flapjacks are very popular in
rock gardens, on rocky embankments, and as perennial
container plants. They make beautiful displays when
planted in mass and their red leaf margins are
particularly attractive. Remember that these plants
are from rocky areas and prefer a similar garden
habitat with plenty of direct sunlight in order to
thrive.
Flapjack
makes for a vivid potted plant or summer succulent
annual in a landscape.
Kalanchoe thyrsiflora
is tolerant of moist but well-drained soils; and,
like its succulent relatives, is very drought
resistant once established. It grows best in full
sun to partial shade. In shade, leaves will be
greener. |

There are more than 50 Bulbine species and
several are used medicinally by traditional healers
in South Africa.
Bulbine frutescens is belong to
Asphodelaceae family. Although Bulbine name comes
from the Latin word bulbus meaning an onion or bulb,
plants do not have a bulbous base.
Snake flower
is native to South Africa, occurs widespread
throughout parts of Northern Cape, Western and
Eastern Cape; however, it reaches its peak in the
succulent-rich, dry valleys of Eastern Cape.
Bulbine
frutescens
is a fast growing, branched, succulent, perennial
with fleshy, linear green leaves in opposite rows
and clasping the stems at the base. It reaches
25-30cm height. It forms spreading clumps with
greyish stems often bearing adventitious roots. The
small 6-petaled star shaped flowers are carried on
an upright, spreading raceme during spring (or
occasionally at other times). The petals are either
yellow or sometimes orange, which combines
attractively with the fluffy yellow stamens to give
a bi-coloured look. The fruit is a small, rounded
capsule and contains black seeds which are dispersed
by wind.
Snake flower is a succulent
perennial, multiplies rapidly. Prune it when untidy.
For best results it should be planted in well-drained
soil preferably enriched with compost. The dead
flower heads should be removed to encourage further
flowering. These plants prefer full sun, but they
will also grow in semi-shade for part of the day.
Although it will grow indoors, it requires maximum
light. The brightly coloured flowers, attract bees.
Propagation of
Bulbine frutescens is from seed,
cuttings or either division of clumps, and should be
done in spring.
Use
in Landscape: Snake flower is often
used in landscaping where a drought-resistant, tough
groundcover is required or in rock gardens. It is a
an easy to grow, waterwise, floriferous groundcover,
which with the minimum of care, will look good all
year round. It combines beautifully with blue dwarf
agapanthus, flowering at the same time.
Bulbine frutescens
is also cultivated for its medicinal properties. It
also has its value in the home garden. The fresh
leaf produces a jelly-like juice that is wonderful
for burns, rashes, blisters, insect bites, cracked
lips, acne, cold sores, mouth ulcers and areas of
cracked skin. This plant is ideal to grow and is a
useful first-aid remedy for childrens' daily knocks
and scrapes. |
