Bleeding Heart Vine – Clerodendrum thomsoniae

Bleeding Heart Vine or Glory Bower, a well-known and popular climbing shrub, is a versatile addition to your house plant collection.

Native to the tropical regions of West Africa, it is the most popular species of a group of over 400 vines, shrubs and trees.

It has woody twining stems and large broad and oblong leaves. The rich green of the leaves is emphasized by a prominent vein patterning.

Flowers and flowering Bleeding Heart Vine flowers from early spring through to the autumn. Ina warm greenhouse, sun room or conservatory this period can be extended so that it flowers virtually all year. The small crimson flowers are carried in drooping clusters at the end of each shoot. The tubular necks of the flowers are surrounded by gleaming white sepals which form the calyx—this protects the delicate growing points of the flower when it is in the bud stage. The red and white of the flower make a strong contrast to the dark green of the leaves.Bleeding Heart Vine - Clerodendrum thomsoniae

Each flower lasts only a short while, but the white balloon-like calyces (the protective sepals) remain on the plant until the autumn. As they age they gradually become pink. The flower of the Bleeding Heart Vine has no fragrance at all.

This plant can grow to 4m (13ft) if planted in a bed or border of a greenhouse, sunroom or conservatory. In a pot it will not usually grow beyond 1.5m (5ft). By pinching out the tips of stems you can train this climber into a bushier, more compact shape.

1. Take 8-10cm (3– 4in) cuttings from the base of side shoots. Remove the lower leaves before planting up. Use a well-drained potting mixture of equal parts of peat moss and coarse sand or Perlite.

2. Cover with polythene or use an electric propagator with a bottom heat of 21°C (70°F). Keep in a well-lit position where a temperature of 21°C (70°F) can be maintained. Keep potting mixture moist.

3. Rooting should take place after 4-6 weeks. Pot into larger pots in a standard soil-based potting mixture.

4. Encourage a bushy shape by pinching out the tips of the stems. When the new plants look well-established and compact, repot into a pot one size larger. Water regularly and during the growing season apply a standard liquid fertilizer.

Pests And Diseases

Emealy bugs indicated by white tufts on stem and leaves.

Prevention: Move the plant out of the sun into the shade.


For a good bushy shape prune back the side shoots to 2-3 leaf pairs when flowering is over or in late winter.

  • Potting: This plant needs plenty of room for its roots and should be repotted in late winter just before the flowering season begins. Use a well-drained peat-based potting mixture.
  • Water regularly, in summer twice a week. Reduce watering towards the end of summer. In winter the plant will need watering about twice a month.
  • Feeding: Apply a standard liquid fertilizer every second week. If the leaves become pale apply a foliar feed. In winter stop feeding.


  • Light: It needs plenty of light, but this should be filtered. Avoid placing it in direct sunlight.
  • Temperature: High temperatures in summer 18-24°C (65-75°F) will suit it best, but remember that it needs high humidity as well. In winter temperatures of 13-15°C (55-60°F) should be maintained.
