Heliconia caribaea aka Wild Plantain

Heliconia caribaea belongs to the Heliconiaceae family. It is a perennial, so it lives for years. It is evergreen and keeps its leaves year-round. People call it Caribbean heliconia or wild plantain. It comes from the Caribbean, including Cuba, Jamaica, and Puerto Rico. Its range includes Hispaniola and the Leeward and Windward Islands. It grows in damp ravines and on moist or wet hillsides. Its broad leaves give it a banana-like shape.

In gardens, it grows 10–15 feet (3–4.57 metres) tall. Clumps spread 3–6 feet (0.91–1.83 metres) across. Plant accounts describe pseudostems, or false stems, about 20 feet (6 metres) tall. These grow from rhizomes, which are stems below ground. The plant has no woody trunk. It grows fast, with an upright, open shape. Its large, tough leaves stay dark green all year. They have smooth edges and pinnate veins, which branch like a feather. Long leaf stalks hold blades 4–5 feet (1.22–1.52 metres) long. These large leaves give the clump a coarse look.

Upright flower clusters grow on stalks in their second year. They bloom in spring and summer. Scarlet or yellow bracts, a type of leaf, surround small flowers. Each bract can reach 6–8 inches (0.15–0.20 metres) long. Hummingbirds carry pollen to pollinate the flowers. Blue fruits follow but add little to the show. Gardeners use this plant as a specimen in tropical gardens. Cut flower clusters can last several weeks indoors. Sources also list it for use as an indoor plant.

It suits moist air in tropical and subtropical climates. The University of Florida lists USDA zones 10b–11. It grows in full sun or part shade. Useful Tropical Plants advises a site with some shade. Both sources favour rich soil that stays moist. Soil rich in humus helps it grow. It accepts sand, loam, or clay, and acid or alkaline soil. It can cope with some drought and soil salt. Feed it regularly during the growing season. To grow more, split well-grown clumps or sow seeds.

Cercospora and Helminthosporum cause leaf spots that can harm leaves. Scale insects and nematodes can cause problems too. The University of Florida reports no known invasive growth. People cook young shoots as a vegetable. The rhizomes yield starch, and reports list seeds as food too. Useful Tropical Plants lists no known hazards or uses as medicine. This lack of known hazards does not prove safety for pets.
