Cheilocostus speciosus commonly known asĀ Spiral Ginger, Cane reed, crepe-ginger, crape ginger, Malay ginger, spiral flag, wild- ginger, variegated ginger and costusĀ is an important medicinal and ornamental plant belonging to genus Cheilocostus and Costaceae (Zingiberaceae) family. The plant is native to Southeast Asia and surrounding regions, from India to China to Queensland. It is especially common on the Greater Sunda Islands in Indonesia. It is also supposedly naturalized in Mauritius, RĆ©union, Fiji, Hawaii, Costa Rica, Belize, Melanesia, Micronesia, and the West Indies. The genus name of Spiral Ginger āCheilocostus speciosusā is derived from the Greek term Cheilo means lip, referring to its large labellum. The species epithet speciosus in Latin means good looking, beautiful, handsome, and impressive, describing its appearance.
Cheilocostus speciosus differs from the common ginger by having only one row of spirally arranged leaves. The species reproduces vegetatively by rhizome, and birds scatter the seeds when they feed on the fruits. The plant is cultivated in India for its medicinal uses, and is cultivated elsewhere as an ornamental. In some areas Cheilocostus speciosus is introduced and has become an invasive species. It is widely cultivated as an ornamental.
Plant Description
Spiral Ginger is an erect, evergreen, ornamental herbaceous and succulent perennial herb that grows about 6-10 feet (2-3m) tall. The plant is found growing abundantly near forest margins, moist places in valleys and roadsides. The plant prefers fertile or humus-enriched and well-drained soil. The cane-like stems emerge from underground rhizomes and are upright, unbranched, and green to dark red in color.
Dried rhizome is curved or somewhat straight, cylindrical, branched piece, 10-30 cm in length and 3-5 cm in diameter in dried condition, upper surface marked with circular nodal scars with remnants of leaf bases, lower and lateral surfaces exhibit small circular scars of roots or few wiry rootlets fracture fibrous and fractured surface is yellowish brown. No characteristic taste or odor.
Leaves
Sub sessile green leaves are simple and entire, elliptic to oblong or oblong-lanceolate, 15-30 cm long or more, about 4-6.4 cm wide, and with pointed tip, glabrous above and silky pubescent beneath and sheathing at the base and are spirally arranged along the stems, giving its foliage a dense appealing appearance.
Flower & Fruit
More dramatic are its snowy-white flowers. Each stem will produce a dark red or brownish-red pinecone-like terminal inflorescence, where large and showy flowers, usually 3-4 at a time, emerge from the ovate bracts. Each trumpet-shaped, frilly and crepe-like white flower, up to 4 inch (10 cm) in diameter, has fused petals forming a large petaloid labellum and exposing a tiny, yellow, petal-like stamen with reflexed tip at the opening of the floral tube. The flowers are followed eventually by roundish to ovoid, red 3-angled fruit capsules, 1.5 cm across, containing black seeds and white flesh that are favored by birds.
