Hibiscuses are deciduous shrubs or small trees with dark green leaves. The plant produces trumpet-like flowers in colours ranging from yellow to red to pink. Grown as an individual tree or low shrub the hibiscus attracts hummingbirds and butterflies to the garden.
Planted in warm frost-free climates the hibiscus can grow to 20 feet tall, according to the University of Florida Extension, though there are low, spreading landscape varieties that reach only 6 feet. Usually the focal point of the garden, hibiscus plants produce large flowers, up to 6 inches in diameter that last through spring and summer. Heavily hybridised hibiscus, grown for shows, reach only 2 feet tall and are bred for elaborate blooms. These are usually only grown by experts, according to the tropical Plants Library Online.
Site Selection and Planting
Hibiscuses grow best in full sun and well-drained soil. Although a plant may not reach its full height, the hibiscus can also grows well in containers and planters. Dig hole as deep as the root-ball and three times as wide. If planting the hibiscus in a container, make sure the container is at least three times wider than root ball to allow the plant to grow properly.
Hibiscus require 1 inch of water per week. Feed the plant twice a month with appropriate plant food during growing season and prune to control size as needed. Pests, such as mealybugs, aphids and white flies are attracted to the hibiscus. If the pests attack the plant, treat it with horticultural insecticide or pest control soap.
