We have seen this small growing Vanda species in Sikkim growing on roadside trees at around 300-500m altitude alongside Vanda ampulacea (see day 130). It grows in exposed positions in good light and survives the dry season (winter) with its thick leaves and abundant fleshy roots.
We grow this species mounted and keep it wet in summer but give it a cooler dry winter by moving it from Warm Asia to hanging in the roof of Cool Americas.
This has to be our orchid with the smallest leaves. As can be seen from the 20p piece the leaves are a few mm long and produced on a creeping rhizome with relatively gigantic flowers produced in a mass in late summer.
We grow the species mounted which it clearly enjoys and avoids the threat of the plant becoming smothered in moss.
The species is native to Brazil where it is found in cloud forests at around 1000m.
This is a small flowered African species and we have seen it growing in Nyungwe National Park Rwanda.
The photo below shows the species growing on the trunk of a small tree on the edge of Kamaranzivu swamp. (1200m)
This shows a plant growing in moss which provides a constant dampness during the wet season though the moss will dry for a while in the dry season (summer) The colour of the leaves and stems also shows that the plant grows happily in almost full sun although other plants were found in more shaded spots.
In cultivation we grow the species in Warm Asia and keep it watered throughout the year. The plant flowers over a period of months as successive small flowers are produced from the flower spike. Although small the flowers are attractively spotted as are the flower spikes making this a rewarding species to grow.
We have seen this large and dramatic orchid growing in cool Brazilian forests along the Rio del Flores in Rio State.
Plants produce a single leaf 30cm long at the top of a ridged pseudobulb and flower spikes emerge as the bulb matures giving around 5-10 12cm wide attractively folded and ruffled flowers (hence the name). The flowers are long lasting if kept dry and in common with related species look upwards for their pollinator and so are worth dropping down when in flower so you can enjoy the best view of the dark lip.
We have seen the plant growing high in trees at around 1000m and so give it cool bright conditions in Cool Americas (minimum 12C). In common with many orchid species it flowers most abundantly when it can get its roots into some dead wood on its host tree and so responds well to feeding when in growth.
This coelogyne species is native to Malaysia, Sumatra, Borneo and Java where it grows in evergreen forest from 1150 to 2100m altitude. Although the habitat suggests the plant would grow cooler we find that the species does best for us in a shady spot in Warm Asia (minimum 18C) where we grow the species in baskets and keep plants wet all year.
Long pendulous flower spikes are produced throughout the year with periods like this week with multiple spikes out together. The flowers are fairly short lived and easily bruised or water damaged but give a fantastic show when at their peak.
