There are 15 species of Allamanda from South and Central America, named by Linnaeus in honour of the Swiss doctor and botanist, Dr Frédéric-Louis Allamand, who visited Guyana in the early 18th century. Allamandas have become popular in gardens throughout the tropics, where some species have become naturalised and even invasive. In temperate countries they are grown as greenhouse plants for their freely produced, brightly coloured flowers.
