Culture Notes
Where summers are hot, provide shade for Mandevilla from direct afternoon sun. Flowers appear in greatest abundance during the summer but some appear all year. When Allamanda is used on a fence or over an arbor, the foliage and flowers will cluster toward the top of the fence or arbor several years after planting. Regular 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. `Alice du Pont' is the most popular cultivar available. Plants look nice planted in containers and hung from an overhead support. Please note that all parts of Mandevilla are poisonous.
