Bletilla striata is lovely terrestrial native to Southern China, Myanmar, Japan and Korea. It grows in open temperate woodland. This is found high in mountains in the south of its range and at lower elevations in the north of its range. We have explored Himalayan temperate forests in Arunachal Pradesh where several uk garden plants can be seen growing in natural splendour. Bletilla straita is therefore a hardy orchid and can certainly take a touch of frost (min -5) and we have friens in Dorset who successfully leave their plants in the ground all year or simply lift and store tubers each winter (like Dahlia tubers). We treat plants as very cool greenhouse plants and growing under glass gives the advantage of easy replication of the wet summers and dryer winters plants recieve in their natural habitats.
Given a little care this species is very easy to grow and multiplies quickly.
We have thousand of seedlings of Bletilla striata in our propagation lab and so are hoping to have seedlings available soon.
