Costus osae is a recently described species from the Osa Peninsula of Costa Rica. In nature, I have usually found it growing on the banks of streams in rocky soil where there is regular moisture but well drained. It is usually in part sun to light shade from the opening in the canopy caused by the steam.
It is rarely found in cultivation or for sale in the commercial nursery trade, but I expect that will change soon. The light green leaves have a felt-like texture, much like Costus malortieanus (velvet stepladder ginger). The bright red bracts stand out beautifully against the light green foliage. Costus osae is a medium height ginger, growing to perhaps 4 feet tall at maturity.
I have tested this ginger for cold hardiness here in Tallahassee (zone 8B) and it has not survived. I am guessing that it is hardy only in zone 9B and warmer.
