Gastrochilus sororius – 365 days of orchids – day 1466

We have another new species flowering in the greenhouse today. Gastorchilus sororius is similar to Gastrochilus calceolus (below) but has thicker leaves and shorter more compact flower spikes with slightly different lips.

Gastrochilus is a lovely genus related to Vanda and all species have interesting small flowers produced is profusion. We have seen Gastrochilus species flowering in cool monsoon forests in Sikkim and Arunachal Pradesh and they can be found across the Himalayas and South East Asia. Gastrochilus sororius is restricted to Borneo, Java, Sumatra and Sulawesi where it grows in warm forests from 1200-1550m altitude.

We grow the species in our Warm Asia section where it enjoys regular watering but very good drainage or the roots are short lived. Gastrochilus species have the advantage of flowering as young plants (as we have seen in their native forests) but in cultivation can make great specimen plants.
