Distribution
Costus spicatus is native to the Caribbean, (including Dominica, Guadeloupe, Hispaniola, Martinique, and Puerto Rico).
Description
Costus spicatus leaves grow to a length of approximately 1 ft (30 cm) and a width of approximately 4 in (10 cm). It produces a short red cone, from which red-orange flowers emerge one at a time. In botanical literature, Costus woodsonii has often been misidentified as Costus spicatus. Both species are common in cultivation.
Cultivation
Costus spicatus will grow in full sun if it is kept moist. It reaches a maximum height of about 6 to 7 feet.
Ecology
Costus spicatus can develop a symbiotic partnership with certain species of ants (often only a single species of ant will be compatible). The ants are provided with a food source (nectar in C. spicatus flowers) as well as a place to construct a nest. In turn, the ants protect developing seeds from herbivorous insects.
Medicinal use
In Dominican folk medicine, herbal tea made from the leaves of C. spicatus is used to treat diabetes (hyperglycemia). However, a 2009 study concluded that this treatment "...had no efficacy in the treatment of obesity-induced hyperglycemia."
