Cordyline indivisa is a monocot tree endemic to New Zealand, where it is called mountain cabbage tree or bush flax. It is also known as the Broad-leaved cabbage tree, and in the Māori language as tōī.
The name Cordyline originates from Greek; the word kordyle, meaning "club," is a reference to the plant's enlarged underground stems. Cordyline indivisa is a slow-growing, evergreen erect tree reaching heights of 3m or more. The lance-shaped, blue-green leaves are relatively broad at 10-30cm wide and from 0.6-2m long with an orange-brown midrib. Small, white, star-shaped flowers borne in dense clusters in summer are followed by tiny purple-blue fruits.
