Verbenaceae

Botanical Name

CLERODENDRUM thomsoniae

Plant Common Name

Bagflower, Bleeding Heart Vine

General Description

Beautiful flower clusters of red and white adorn this West African flowering vine when growing conditions are favorable. Bleeding heart vine is evergreen, though it will lose some leaves during the cool, dry African winter. It is vigorous and climbs via twining stems. In the wild, it twines up trees in tropical forests, so it’s naturally shade tolerant.

The dark green leaves of bleeding heart vine are ovate and deeply veined. During the growing season, or when conditions are favorable, it bears many pendulous clusters of flowers. The blooms have heart-shaped, papery white calyces that surround tubular flowers of scarlet. As the flowers age, their calyces darken to rose-pink. The bird-pollinated blooms attract hummingbirds, if grown in American gardens. Small, bright, orange fruits with black seeds follow.

Bleeding heart vine grows best in partial shade and well-drained, average garden soil that is near-neutral in pH. The flowers are borne on new foliage that emerges in late winter, so be sure to prune vines towards the end of the growing season, not in spring. Fertilize regularly to ensure continuous flowering and supply regular moisture when vines are actively growing. Allow potted specimens to become somewhat dry between watering and reduce water during the winter months when growth slows down. In temperate climates, bleeding heart vine can be grown indoors as a conservatory specimen or outdoors in a large planter or hanging basket. Where hardy, it can be grown along a fence, trellis or tree.
