Cordyline is a genus of 15 species in the family Asparagaceae native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia, Polynesia and Hawaii. Eight species of Cordyline are native to Australia:
- Cordyline cannifolia
- Cordyline congesta
- Cordyline fruticosa
- Cordyline manners-suttoniae
- Cordyline murchisoniae
- Cordyline petiolaris
- Cordyline rubra
- Cordyline stricta.
Of these, two naturally occur on the Sunshine Coast; Cordyline petiolaris and Cordyline rubra. Recently I have noticed Cordyline manners-suttoniae coming up in weedy proportions within a few reserves on the Sunshine Coast. Cordyline manners-suttoniae is similar in appearance to Cordyline petiolaris and makes me wonder if it may have been planted by mistake. Cordyline manners-suttoniae naturally occurs from Cooktown to Gladstone. A few slight differences in leaf shape and petiole shape and size can help to tell the two apart. It is a concern that these two species could hybridize, making it even more difficult to determine which is which.
