Costus bracteatus is from the Caribbean side of Costa Rica and Panama. It is closely related to C. guanaiensis and at one time was lumped with that species. It has similar bracts and flowers except that the inflorescence is pendent and grows to a long and beautiful hanging garland, either from a basal stem or a terminal stem. The flowers are open white with red stripes. The plant can grow to about 6 feet tall.
I have never tested it outdoors over winter, but I would presume it to be tender and require growing in a greenhouse anywhere colder than UDSA zone 9B. It needs part shade to full light shade as the leaves will burn in full sun.
