Large clusters of long-lasting, light lavender, mauve, to purple calyxes serve as the backdrop for the contrasting deep red, 1" wide, butterfly shaped flowers that are produced throughout the warmer months of the year, as early as midspring to about mid fall. The Red Bleeding Heart Vine, Clerodendrum x speciosum, is a naturally evergreen, heirloom, twining, tropical climber that is one of the better and more reliable flowering vines for shaded areas, although it can also take full sun, if acclimated, where it may be even more floriferous, and it attracts butterflies and likely hummingbirds. I have always found it interesting that many of the butterfly and moth pollinated species in the genus Clerodendrum appropriately have butterfly shaped flowers. The colorful bracts have the deepest purple coloration in full to partial sun conditions. Provide the Red Bleeding Heart Vine with a moist to average moist, fertile, average to well-drained soil for optimum vigor and flowering. This is a hybrid of the White Bleeding Heart Vine,
