Cordyline fruticosa

Cordyline fruticosa is an evergreen flowering plant in the Asparagus family, Asparagaceae, known by a wide variety of common names, including cabbage palm, good luck plant, palm lily, ti plant, Kī, Lā‘ī (Hawaiian), Tī Pore (Māori), Sī (Tongan), Lauti (Samoan), and ʻAutī (Tahitian).

Formerly treated in the families Agavaceae and Laxmanniaceae (now both subfamilies of the Asparagaceae in the APG III system), it is a woody plant growing up to 4 m (13 ft) tall, with leaves 30–60 cm (12–24 in) (rarely 75 cm or 30 in) long and 5–10-centimetre (2.0–3.9 in) wide at the top of a woody stem. It produces 40–60-centimetre (16–24 in) long panicles of small scented yellowish to red flowers that mature into red berries.

It is native to tropical southeastern Asia, Papua New Guinea, Melanesia, northeastern Australia, the Indian Ocean, and parts of Polynesia. It is not native to either Hawaii or New Zealand but was introduced to both by Polynesian settlers.

Cultivation and uses

The species was spread from its native range throughout Polynesia as a cultivated plant. Its starchy rhizomes, which are very sweet when the plant is mature, were eaten as food or as medicine, and its leaves were used to thatch the roofs of houses, and to wrap and store food. The plant or its roots are referred to in most Polynesian languages as tī. Māori ranked the sweetness of the plant above the other Cordyline species native to New Zealand.
