Mandevilla splendens Pink Allamanda1

Edward F. Gilman2


Quickly twining around any support, or pinched to create a handsome hanging specimen, pink allamanda is an attractive evergreen vine endowed with beautiful, deep pink, funnelform blooms up to four inches wide and two inches long, set off against dark green, large evergreen leaves (Fig. 1). 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 pink allamanda become popular as an annual in cooler regions where freezing temperatures kill the plant to the ground.
