Epidendrum Orchid, The Largest Genus of Orchids
Epidendrum orchids is the largest genus in the orchid familia. This genus
includes more than 1,100 species hence it is a mega genus. Epidendrum orchids
are also called epi which is named after their habits that grow on trees like
epiphytes. But actually not all epidendrum orchids live on trees, and some are
not even considered as epiphytes at all.
It was Carolus Linnaeus that included all the orchids which he recognized
and considered as epiphytes. In 1763 he introduced this genus which later was
then reviewed and revised where some orchids were moved to other species and
sub-species. The review and revision went on and until today about 2,000 names
are listed, among those about 1,000 have been established into a new genera.
Still, there is an estimation of more or less 2,000 undiscovered epidendrum
orchid types out there.
The majority of epidendrum orchids are native to the tropical and
subtropical regions of Asia as well as America . They mostly live upon
trees (epiphytes), although some live on grounds (terrestrial type) and only a
few live on rocks (lithophytes). Their habitats are the tropical and humid
jungles. However epidendrums can also survive on green fields or under the
trees of cool forests. That is why epidendrums are regarded as sustainable
orchids.
Unlike the majority of epidendrum orchids that
live in tropical areas, there are some types that are able to survive in cool
conditions like the Epidendrum radicans. The Epidendrum conopseum
can even stay alive in prolonged freezing conditions of Auckland . In this extreme low temperature it
is still able to bloom the whole year long.
The size and form of the flowers are available in a number of varieties.
They produce flowers in clusters in the form a receme (or unbranched
inflourescences). In some occasion they also bloom in the form of panicles (or
compound recemes) with longer flower stalks. Most of the upper, lateral and
lower side flowers are small to medium sized and is a bit difficult to see
them.
The one and only attractiveness to these epidendrum orchids are their very
pleasant smell. Many types of epidendrums produce pleasant fragrance which is
the best reason to caring for this orchid. Epidendrum aromaticum and Epidendrum
cochleatum are some of them which are able to flourish to spread pleasant
smell from summer to autumn, but E. cochleatum needs a bit warmer temperature.
On the other hand, Epidendrum moyobambae and Epidendrum radiatum
are two examples of fragrance orchids that blooms in spring to summer
Epidendrums have very minimum features to offer, since their flowers are
unattractive and very small compared to other orchids. However, there are some
that have beautiful flowers. One of the few epidendrums that possess beautiful
flowers is the Epidendrum radicans which you can consider to be listed in your
orchid collection.
E. radicans is some kind of wild-plant orchid that you may find along the
roadsides of Central America . It produces long
fluorescence of flaming-red flowers which could reach a length about 15 inches.
It has a long flowering time when kept in warm to cool temperature on
terrestrial orchid-mix as potting media.
Epidendrum pfavii or the ‘Purple Gum Drop’ is another one that has attractive
flowers. This native to Costa
Rica orchid grows with an erect stem which
is able to grow up to four feet tall. It produces a huge quantity of pink to
purple colored flowers that flowers at the edge of the stem. If you like to
care for one, the best media for cultivation is on barks or a coarse media
which provides good drainage. It is a thrifty type of orchids, thus you do not
need to use a fertilizer to get optimum results.
In spite of their only few positive traits, epidendrum orchids are quite
easy to propagate. A single stem can produce many plants with a broad range of
tolerability and growth conditions. These new types are best cultivated on bark
compost-mix, sphagnum moss and fibers of tree branches. They are also very
tolerable to high temperatures up to 100F without showing any sign of harm or
suffering.
The conclusion: In spite of their minimum of good features to offer, there
are types of epidendrums that possess positive traits: their pleasant smell and
some of them with beautiful flowers plus their ‘stubbornness’ you may
definitely include one in your orchid collection.
