Introduction
The many species of heliconia are rainforest herbs that occur within the understory or densely at the forest periphery. A few rapidly colonize temporary tree-fall gaps or occur in the open along streams or in disturbed areas. They range from not much more than 1.5 feet in height to nearly 15 feet tall. The relatively inconspicuous flowers are borne in extravagantly colored bracts that are waxy and long lasting and have become high-priced tropical cut flowers. Some of the species bear pendant inflorescences, and these can be as long as several feet.

Use and Management
As landscape plants, many Heliconia species are less desirable because of their spreading nature and the tendency of the leaves to become tattered along the veins by wind. H. psittacorum (to 5 feet tall) and its many hybrids (known as Parakeet Flowers), are frequently used as landscape perennials. However, their aggressive spreading nature requires effective root barriers to keep the rhizomes from extending into areas where the plant is not wanted. H. caribaea, well-adapted to alkaline soils, is a tall-grower (to 12 feet) with deep red-bracted inflorescences borne on 2-year-old stems. The many varieties of H. stricta rarely grow taller than 3 feet. Heliconias as a group impart an unmistakable tropical look to the garden. Heliconias can be used as specimen plants, or they can be massed together in groups.
Heliconia species should be grown in full sun to partial shade on a well-drained soil. These perennials have no drought or salt tolerance but will endure wet soils. When these plants are occasionally frozen in the warm parts of Florida, the tops will die back to the ground, but roots will regenerate new shoots with the coming of warm weather.
Propagate the Heliconia species by division.
Pests and Management
These species are relatively pest tolerant.
