Clerodendrum thomsoniae (Bleeding heart) is a popular, evergreen, deciduous vine native to Tropical and Central Africa. Hardy in USDA Zone 9-11, it prefers full or semi-shade to grow and thrive in, although it can tolerate short durations of full sun in cooler climates. Regular water is required to ensure healthy growth, but this drought-tolerant plant can withstand some dry periods. This showy creeper is noted for its heart-shaped blooms of white and off-white edged in bright crimson. In addition to its eye-catching flowers, the plant is also attractive to butterflies and hummingbirds. Clerodendrum thomsoniae can survive a short time in temperatures down to 30°F. It tolerate some salt spray that makes it an effective seaside plant.
Growing Clerodendrum thomsoniae in pots can be achieved in colder regions, provided the container is well-draining and offers adequate sunlight. During the winter months, keep the plant slightly drier and protect from excessive frost. Fertilize in spring and summer with a balanced liquid fertilizer. Prune lightly after flowering to help shape the growth and keep it in check. Regular repotting will ensure the plant receives the nutrients it needs to bloom in abundance. Finally, keep the pot free from weeds and waterlogged soil as this is a sure-fire way to kill off this fabulous evergreen creeper.
