GINGERSRUS CATALOG LISTING:
Costus lateriflorus flowers This is a rare African Costus that is epiphytic in nature and grows almost like a vine, with long thin stems that twist and turn in typical Costus fashion. Mature stems seem to stop at about 3 feet long, but perhaps would grow longer under some conditions. The leaves are shiny, medium green and the flowers form in clusters at the leaf axils, unlike any most other Costus which either flower terminally on a leafy stem or basally on a short leafless stem or direct from the rhizome. The flowers are BEAUTIFUL!!! The labellum is a bright yellow color with reddish spots on the stamen to attract bees - the most likely pollinators. The corolla lobes are translucent.

I have not tested this one outdoors, but I seriously doubt it would be hardy below 40 degrees. It should be grown in pots in a very loose, free-draining medium, in warm, humid conditions year round. I have grown it in very strong sunlight with no indications of leaf damage, but also in part shade, indirect light and under 20% shade cloth - so it seems to do fine under a wide range of light conditions.
