Use and Management
It looks particularly attractive twining along a fence or over an arbor or mailbox. Foliage and flowers cluster toward the top of the fence or arbor several years after planting. Regularly heading back several of the twining stems each year will help generate new foliage and flowers near the ground. Rapid growth and profuse flowering have helped allamanda become popular as an annual in cooler regions where freezing temperatures kill the plant to the ground.
Growing best in full sun, allamanda needs well-drained soil and should receive ample moisture during the growing season. Flowers appear in greatest abundance during the summer but some appear all year.
