Glory bush (Tibouchina urvilleana)
Tibouchina urvilleana, aka glory bush, is on the State of Hawai’i Noxious Weed List and is also known as lasiandra, princess flower, glory tree or longleaf glory tree. It is illegal to sell or transport all 350 species of the genus Tibouchina in Hawai‘i. Glory bush is native to Brazil, but the plants have been grown as popular ornamentals and have escaped cultivation in Hawai‘i. Glory bush is an aggressive colonizer of disturbed areas that can create monotypic thickets that displace native emergent species.

- Leaves are oval shaped and velvety, about 4-12 cm long (1.5 – 4.5 inches) and 2-5 cm wide (.75 – 2 inches)
- Flowers are showy and purple, with 5 petals about 20-40 mm (.75-1.5 inches)
- Fruits are inconspicuous small, round, hard capsules <.5 inch
- Tibouchina urvilleana threatens native areas by forming monotypic thickets that outcompete and displace native plants.
