Visitors to Orchid Christmas will be able to enjoy a very diverse greenhouse include several of our Stelis species. Stelis genychila is one of the highlights of our autumn greenhouse with its really unusual unusual large dark flowers.
Stelis is a genus closely related to Masdevallias and Pleurothallis. They are not widely grown in collections but the orchid project has been a big fan since exploring the forests of Brazil and Costa Rica where students came across many of these small flowered but very attractive species.
Stelis genychila like most Stelis species has flattish flowers with three larger sepals, forming a triangle, and much smaller petals and lip in the centre. These parts are easier to spot in Stelis genychila than many stelis species as the flowers are rather large and beautifully coloured.
The plant is medium sized for a stelis with leaves about 20cm long and the 30cm flower spikes have two opposite rows of 10-20 flowers. Leaves flower repeatedly over many years and so mature plants produce many spikes. We find that this species is a regular autumn flowerer and have noticed that the flowers open with a grey tone and slowly darken as they mature.
All of our Stelis species grow in our Cool Amaricas section (min 12C) where they are grown wet (we water every day) all year in pots or baskets.
