Bleeding Heart Vine (Clerodendrum thomsoniae) is a soft-stemmed twining climber prized for its dramatic flowers: pure-white, lantern-like calyces from which vivid crimson blooms emerge, creating a striking two-tone effect. Native to tropical West Africa, it grows well across warm, humid parts of India on trellises, arches and balcony railings, or trained in large pots. The glossy dark-green leaves set off the flower clusters that appear mainly through the warm months. It prefers bright, filtered light and steady moisture, making it ideal for partly shaded patios. Moderately vigorous and easy to train, it can be pruned hard to keep it tidy.
