Odontonema tubaeforme is a plant in the family Acanthaceae native to Central America and naturalised as a garden escape in numerous other countries.

tubaeforme is native to Central America,[6] but has naturalised in several countries as an ornamental garden plant, including New Zealand and Australia.

Since 2005 it has been recorded in the wild in the far north of New Zealand, at Auckland, Kaitaia, and Doubtless Bay.

In New Zealand it usually spreads through the dumping of garden waste, although in one locality (Cooper's Beach) seedlings have been found.

[5] In the Pacific it is considered an invasive species, and has recently naturalised in Rarotonga and Mangaia in the Cook Islands.
