Photographed in a front garden from over the fence. I couldn't get closer without entering the property. The flowers were spectacular in the evening sun.
Does anyone know the genus Tibouchina well enough to say what species this is? I see that there are 11 known in cultivation in NZ. Tibouchina urvilleana looks like a good match.
The family Melastomataceae (alternatively Melastomaceae) is a taxon of dicotyledonous flowering plants found mostly in the tropics (two thirds of the genera are from the New World tropics) comprising some 200 genera and 4500 species. Melastomes are annual or perennial herbs, shrubs, or small trees.
