Cordyline

Cordyline is a genus of about 24 species of woody monocotyledonous flowering plants in family Asparagaceae, subfamily Lomandroideae. The subfamily has previously been treated as a separate family Laxmanniaceae,^[2] or Lomandraceae. Other authors have placed the genus in the Agavaceae (now Agavoideae). Cordyline is native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia and Polynesia, with one species found in southeastern South America.

Cultivation and uses

Members of the group are often grown as ornamental plants - notably C. australis and C. fruticosa. Many species have been used as a foodstuff and medicine, for additional details on these and other uses see the article on C. australis. The rhizome was roasted in an hāngī (earth oven) by Māori to extract sugar.^[6]

In the highlands of Papua New Guinea. leaves of Cordyline and other plants are tied to sticks to mark taboo areas where pandanus language must be spoken during karuka harvest.^[7]
