Another thank you to Rosa, aka contemplar@Flickr, for sharing a photograph with BPotD (original | BPotD Flickr Group Pool). Like the previous time a photograph of Rosa’s was featured, if you visit Rosa’s weblog, Blog De Cheiros, you’ll find an entry about this species with more photographs.
Montanoa hibiscifolia is commonly known as tree-daisy or, in Australia, the Anzac flower. Native to Mexico and Central America, it has been cultivated in a number of tropical areas. Unfortunately, it has become weedy in many places where it’s been introduced for ornament including Hawaii (or read this PDF fact sheet), northern Queensland of Australia (PDF) and Zimbabwe.
Tree-daisy is a woody member of the aster family. It can reach heights of 8m (26 ft) and form dense stands. The link to the Hawaiian web page above shares more photographs of the plant, where you can more clearly observe that hibiscifolia, meaning “leaves of Hibiscus”, is well-deserved.
