Description: The flowers are in large, leafy, chandelier-like, up to 18 inch (45 cm) tall, panicle-like inflorescences at the branch tips. The individual flowers are white, tubular, drooping, 4 inches (10 cm) long, and have 5 round-tipped lobes, long, reddish stamens, and an even longer style. The flowers are followed by a cluster of 2 to 4 round, leathery, shiny, green ripening to dark blue fruits enclosed by a shiny, red, pitted, 5-pointed starlike calyx. The light green calyx at the base of the flowers enlarges and turns red as the fruit develops. From a distance, the fruiting clusters look like red flowers. The leaves are green, hairless, sessile, smooth-edged, lanceolate in shape, and opposite or whorled with 3 to 5 leaves per node. The plants are tall, narrow, and ungainly-looking with just a few slender, arching or leaning branches.
Here in Hawaii, Turk's Turban grows in disturbed areas and along roadsides in wet to mesic (moderately wet) areas at lower elevations.
