There are 150 different species of columnea. They come fromCentral America, South America, and the West Indies; their natural habitat is the dambdamp tropical forest.
Because they are semi-upright or trailing plants, they look especially fine in hanging baskets. The brightly colored, tubular flowers are orange, scarlet, or yellow, and many hybrids bloom continuously throughout the year. Two of the better-known hybrids are “Early Bird” and “Mary Ann”.
