Argyreia nervosa (Hawaiian Baby Woodrose)

Native from the Indian subcontinent to Myanmar, this evergreen woody vine can grow about 30 to 50 feet long. Its leaves and young stems have a distinctive silvery covering of hairs underneath. Its flowers are pink to purple and trumpet-shaped. The persistent sepals around the fruit form a rose-like structure, giving it the name woodrose. Its seeds contain psychoactive alkaloids, including ergine, and can cause hallucinations. In northern Queensland, Australia, it is invasive in rainforests and other tropical forests, where it can smother trees. Photographed in Miami, Florida.
