Most of the orchids we grow at school are epiphytes (grow on trees) but this Jewel orchid is a terrestrial (grows in the ground) and is quite commonly available. Jewel orchids include a large number of terrestrial orchids prized for their patterned leaves although several, like this species, have attractive flower too.
Ludisia discolor is native to evergreen lowland forests across South East Asia and is reported from 70-1100m in shaded damp situations in leaf litter (growing in the ground often does not mean growing in soil). As a result plants prefer warm shaded conditions and plenty of water. We have seen advice to grow plants in potting compost but we use our standard bark mix with a little sphagnum moss.
Several jewel orchids are threatened by unsustainable collection for horticulture so sources should be checked carefully but Ludisia discolor is very easy from seed in the lab and plants in cultivation in the uk are seed raised.
