Botanical Profile

Culture & Tradition

Native to tropical Asia, naturalized in Hawaii and Pacific islands. This herbaceous perennial grows 3–5 feet tall from rhizomes. The leaves are alternate, lanceolate. The inflorescence emerges separately on a short stalk: a basal, cone-like structure of overlapping bracts (green turning red), from which small, white-yellow flowers appear. The bracts fill with a fragrant, mucilaginous liquid.

It thrives in part shade, rich, moist soil, and humidity. Hardy in zones 8–11 (rhizomes survive freezing). The gel is used for hair/skin care. The rhizomes are edible but bitter. A fascinating, useful plant for tropical gardens and ethnobotanical interest.
