This is one of our favourite miniature orchids. The species comes from Papua New Guinea where it grows in shady forest up to 2500m. Mediocalcar decoratum’s small bell shaped flowers in orange and yellow suggest that the likely pollinator is Sun Birds. Sun Bird’s are Africa and Asia’s version of South America’s Humming Birds and we saw some lovely species in Rwanda.
We grow this species mounted on cork bark in Cool America’s (we don’t have a Papua section) where it seems very happy with a minimum of 12C and coolish summers.
