Maui chaff flower (Achyranthes splendens) is a native Hawaiian shrub, with two varieties, that grows in dry forests, shrublands and sandy shores and is threatened by habitat loss. It is drought- and salt-tolerant, so it suits dry, sunny, well-drained sites; the var. rotundata is endangered and permits are needed to grow it commercially.

About

Achyranthes splendens (ʻEwa hinahina; also called Maui chaff flower, round chaff flower, round-leaf chaff flower, or round-leaved chaff flower) is a species of flowering plant in the pigweed family, Amaranthaceae, that is endemic to Hawaiʻi. Its natural habitats are dry forests, low shrublands, and sandy shores. It is threatened by habitat loss.

Where it grows

A. splendens var. splendens is found naturally on Lānaʻi and Maui, while A. splendens var. rotundata is considered endangered. Wild populations of A. splendens var. rotundata are closely monitored in locations on Oʻahu, including Kaʻena Point, Kalaeloa, Mākaha, Kahuku, and Campbell Industrial, as well as at Mokio on Moloka‘i, after going extinct on Lāna‘i. Historically, A. splendens var. rotundata was often found around the ‘Ewa Plain area, giving it the nickname, ‘Ewa hinahina. This variety is salt- and drought-tolerant and can be propagated through seeds or cuttings, but permits are required to grow them commercially due to their endangered status.
