Approximately 150 to 200 species of Costus are mostly found in the tropics of the southern hemisphere.
As the common name suggests, the Costus
family is closely related to the ginger family. This species is native to Central
and South America. Leaves are arranged
spirally on upright stalks and the plant spreads slowly by rhizomes. Yellow to
orange tubular flowers emerge from red or green cone-like inflorescences at the
top of the stem. These tropical plants are evergreen in warm climates.

Spiral ginger is an easy plant in part shade. Irrigation may
be required during prolonged dry spells. In north Florida, it may die to the ground in winter
and re-emerge in spring.
