About plant names...
Costus is a genus with over 100 members, plants with spiraling stems that otherwise resemble ginger.
This species is native to Panama, Costa Rica, Nicaragua, and Colombia, found in North America as a
cultivated plant. In Hawaii, it has become naturalized in some areas.
Identification: Shrubs are 24-36" (60-91 cm) in height (dwarf form),
and up to 12' (3.7 m) for a larger form. Leaves are glossy, cordate, dark green, arranged spirally around
the stem, and elliptical to egg-shaped. Flowers form at leaf tips, egg-shaped or cylindrical,
never opening completely. Shiny, tightly overlapped bright red bracts bracts
look a bit like a partially melted red candle.
