| Orchids,
Palms and Cycads are the main collections of the Gardens, and
the focus of present and forthcoming collection efforts. It is
our intention to maintain the cosmopolitan flavour of our cycad
collection, which is currently ranked among the top ten botanical
garden cycad collections in the world.
Palm and
orchid collections will increasingly focus on documented accessions
of African species. World-wide, botanic gardens are changing,
as threats to plants and ecosystems become more grave. Ironically,
this makes it an exciting time for botanic gardens, as their multiple
possible roles in conservation and education are recognised by
governments and international agencies.
Fundamental
to our participation in these new challenges, is the development
of conservation-significant plant collections, and professional
management of these collections. Unless our collections are curated
comparably with those of the world's top gardens, then attempts
to increase their educational and scientific value are diminished.

Our Orchid collection began in 1931. Mr. Ernest Thorp started
the collection while he was a student. It consisted of two dozen
orchids imported from India.
Much later
the then Curator, Mr. Frank Thorns and his orchid students bought
24 Cattleya mendellii and 25 Cattleya gaskelliana orchids from
the Port Elizabeth Parks Department. This increased the collection
to 74 orchids. Ernest Thorp was approached by Douglas Mackeurtan,
who wanted to learn the art of orchid culture, and between them
they built up the collection to some 300 plants. In 1945 this
collection was bequeathed to Ernest Thorp. During the 1950's and
60's there was an orchid explosion in the USA due to the advent
of tissue culture.
A few local
orchid collectors got together and each purchased a particular
orchid hybrid for mutual exchange amongst themselves.
Thus by 1960
the Durban Botanic Gardens collection was substantial and in 1962
the Ernest Thorp Orchid House was opened.
The best
flowering times for orchids are spring and autumn..... Bromeliads
are used to augment the absence of orchids during the non-flowering
times.
There is a separate Species Orchid House for species orchids,
which have smaller blooms but have the perfume that the other
hybridized orchids lack

The bromeliads in the Durban Botanic Gardens are one of the main
collections of the Gardens. Durban having a hot humid climate
is ideal for a number of these plants.
"Bromeliads"
is simply a shortening of the scientific name Bromeliaceae, the
Pineapple family.
It is not possible to say who first coined the word "Bromeliad"
but it was probably some fairly recent botanist or horticulturist
who was tired of having to use the phrase "species of Bromeliaceae".
It was Linnaeus who established the genus Bromelia in 1754. The
name was taken from the family name of Olof Bromelius, a Swedish
botanist.
Bromeliads
previously went by the Indian name of Karatas.
A
peculiarity of the family is its limited distribution. All "Broms"
are native to the Americas. Their occurrence is limited by climate
conditions- temperature being a main factor.
Tillandsias
have the widest distribution. Many species are inhabitants of
the tropical rain forests. These cover vast expanses of the lower
Amazon basin. The a large part of the forest floor is water- covered
during March and April when the rivers reach flood stages. The
Bromeliads have taken to the trees and most of the epiphytic species
are found here.
Most of the Broms which grow in the rain forest are the soft-leaved
unarmed with thorns or scales. Most have the magnificently coloured
inflorescences. Their light requirements are comparatively low
as they are situated below shading leaf-crowns and foliage masses.
Bromeliads
growing in regions with limited rainfall and thorny bush growth,
have stiff, well-armoured leaves e.g. Aechmeas and Ananas.
These
plants are pronounced sun lovers, are drought- resistant and are
for the most part terrestrials.

Palms are a fascinating group of plants, related to grasses but
with complex reproductive strategies. They have an ancient lineage:
the first palm fossil (leaves of Sabal species) dates back to
the upper Cretaceous Period, 84 million years ago. Palms have
a wide distribution and are found in tropical and subtropical
regions, and also occur in desert areas where permanent ground
water is available. Only a very small number of palms grow in
temperate countries.
Here at Durban Botanic Gardens,
we have an extensive palm collection of more than 130 species
from 58 genera. The beautiful Palm Walk was established in 1889
and today contains a majestic stand of palms lining the avenue.
The Palmetum partly surrounds the lake in the grounds and was
created in 1977. The collection has a diverse group of palms,
ranging from the Giant Fishtail Palm of Borneo which grows to
over 25m in height, to the small Chamaedorea palms which grow
in the understory of rain forests.
Many palms are threatened with
extinction in the wild especially those which occur in tropical
rain forests or on small islands. Here, the removal of rain forest
habitats for timber, agriculture, pasture and mining are seriously
endangering palms throughout the world. The removal of seeds and
plants from the wild by unscrupulous palm collectors is another
important factor in the conservation status of many rare palm
species. Often seeds from whole stands of palms are taken illegally,
isolating populations and bringing them even closer to extinction.
Here at the Durban Botanic Gardens,
we are in the process of creating a seed bank of our palm species.
The primary aim is to ensure that the gene pool of each species
is as genetically diverse as possible. This could, in future,
supplement endangered wild population and be of use in re-introduction
programmes.
