- Description
-
Kahali Ginger is an herbaceous, flowering perennial in the ginger family native to India, Nepal, and Bhutan. It has thick fleshy rhizomatous roots that spread and form colonies. Kahali Ginger is an erect and clumping plant that can reach a mature height of 8 feet with tropical-looking foliage. The flowers are very fragrant, blooming in late summer. Kahali Ginger is considered an invasive plant in Hawaii where each plant will spread rapidly by stolons, creating dense mats that crowd out other plants. The conspicuous, fleshy, red seeds are dispersed by birds as well as man.
These tropical plants prefer moist, well-drained, organically rich soils in full sun. They lend a tropical look to the garden as well as fragrant flowers. Use in groups, borders or containers. They are typically grown as an ornamental in containers, but it can tolerate an occasional frost. While best taken indoors in winter months, it can be maintained in a warm, sheltered spot with deep mulch and where temperatures do not fall below freezing.
