Botanical Name: Clerodendrum thomsoniae
Bleeding Heart Vine makes a beautiful flowering house plant. Train it on a trellis or prune it back -- you can grow it any way you like.
This tropical beauty is covered with attractive deeply veined, ovate leaves. Its glory, however, are the eye-catching red and white flowers that bloom profusely from spring through fall. Made up of snowy white calyxes, the blooms are somewhat heart-shaped. Emerging from each calyx is a bright red flower with long stamens.
You'll find this beautiful vine for sale at nurseries and online in spring and summer. It's usually known as Bleeding Heart Vine and sometimes as Glorybower. Look for the botanical name Clerodendrum thomsoniae to be sure you're getting this plant.
As if this plant isn't showy enough, a variegated variety exists. C. thomsoniae 'Variegatum' features marbled green leaves.
Repot in spring only when it has outgrown its container. Bleeding heart blooms best when it is slightly pot-bound, so move it up to a pot only 1 size larger. Use a pot with drainage holes to prevent soggy soil.
Prune vines back in spring, when bleeding heart vine is beginning new growth. Flowers grow near the tips of new stems, so you'll get more blooms this way. You can cut the vines back by as much as half, if you want, to keep the plant at a manageable size for growing indoors.
Raise the humidity if the relative humidity near the plant drops below 50%. You can place the pot on a tray of wet pebbles. Or use a cool-mist room humidifier. Raising the humidity also helps to prevent spider mites from invading. Watch for these pests, especially in winter when indoor air tends to get dry.
Give it a winter rest. This tropical vine is an evergreen perennial, but it may stop flowering in the fall and winter months and growth slows down. Unlike the popular shade-loving Bleeding Heart Plant, this vining plant won't overwinter in the garden, unless you live in a tropical climate. Give it warmth, humidity and bright, indirect sunlight year-round. Water sparingly during this rest and stop fertilizing till spring when you see new growth on the plant.
Origin: Tropical West Africa
Height: Up to 6 ft (1.8 m) if not pruned back
Light: Bright indirect light. Bleeding heart is a prolific bloomer when it gets enough sunlight. It blooms heavily in spring and summer. If it doesn't bloom much, move it to where it will get more light from a south- or west-facing window.
Water: Keep soil evenly moist spring through fall, while bleeding heart vine is growing and flowering. Water sparingly in winter, but do not let it dry out completely.
Humidity: Aim to maintain 60% humidity -- or higher -- around the plant year-round. This is easier than it seems; set the plant on a pebble tray or use a cool-mist room humidifier. It's a good idea to use a humidity gauge rather than guess -- air can become extremely dry indoors during the winter months.
Temperature: Average to warm (65-85°F/18-29°C) year-round
Soil: Good-quality potting mix
Fertilizer: Feed every 2 weeks in spring and summer with a high-phosphorus water-soluble fertilizer.
Propagation: Easy to propagate from stem cuttings. Take 3 in (8 cm) stem tip cuttings in spring and root in equal parts all-purpose potting mix and perlite.
