When a plant’s common name has “glory” in it, you might guess the plant is something special. And in the case of

Clerodendrum

(also known as

Clerodendron

), you’d be right.

Species in this genus — some hardy to Zone 7 or 8 and others suited for tropical climes — have a powerful presence, but in different ways.

Take

Clerodendrum bungei

, for instance, a deciduous shrub that breaks out in large clusters of hot-pink buds that open into lighter-pink, pleasantly scented stars, blooming sporadically into September.

The upright shrub grows to 5 or 6 feet tall, with heart-shaped leaves that emerge in deep burgundy and fade to dark green; it’s shade-tolerant and easy to grow.

There’s just one problem, but it’s a big one: the rancid aroma of the foliage. Plant this species downwind or not at all. It also has a suckering habit, so give it room. Full sun or part shade is fine.

A better choice for those with sensitive noses is

C. trichotomum

, the harlequin glory bower – often called the peanut-butter tree because of the aroma of its leaves when crushed.

The flowers have a sweet fragrance (not at all peanut-buttery), which can often be smelled a block away.

The star-shaped white blossoms, each set off by a dusty-rose calyx, appear in August.

They turn in September into turquoise fruit set in a blaze of red (the new hue of the calyxes).

Often grown as a multistemmed, open shrub, harlequin glory bower is easily trained into superb, 15-foot ornamental tree. Site it in full sun to part shade, and well-drained soil.

C. trichotomum

var.

fargesii

is similar but hardier, more freely fruiting and less colorful.

And

C. trichotomum

‘Carnival’ has variegated leaves.

No space in the yard for another tree? There’s a

Clerodendrum

for the indoor grower, too. The bleeding heart glory bower,

Clerodendrum thomsoniae

, has red-and-white, heart-shaped flowers that are a study in color contrast. This houseplant will bloom for as long as three months and, with minimal care, may bloom several times in a year. Provide a warm, sunny location, high moisture and regular feeding.

Or grow it as a quick summer vine on a small trellis. It can grow as much as 6 feet in a season and flowers from midsummer on.

Similarly,

Clerodendrum ugandense

, the blue glory bower, a sprawling shrub with striking blue-and-white flowers that can be trained as a vine, can be grown indoors, or as a summer annual outdoors.

Bleeding Heart Vine

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.

Clusters of gorgeous blooms decorate Clerodendrum thomsoniae.

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.

Caring for Bleeding Heart Vine Year-Round

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.

Clerodendrum thomsoniae makes a stunning flowering houseplant.

Pruning Tip

Always prune above a leaf node (the place where a leaf is attached to the stem). Use sharp, clean pruning shears to avoid jagged tears and disease.

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.

Bleeding Heart Vine Care Tips

Photo credit: United States Botanic Garden

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.

Clerodendrum Bleeding Heart Care: How To Grow Bleeding Heart Vines

Also known as glorybower or tropical bleeding heart, Clerodendrum bleeding heart (Clerodendrum thomsoniae) is a sub-tropical vine that wraps its tendrils around a trellis or other support. Gardeners appreciate the plant for its shiny green foliage and dazzling crimson and white blooms.

Bleeding Heart Information

Clerodendrum bleeding heart is native to western Africa. It is not related to the Dicentra bleeding heart, a perennial with dainty pink or lavender and white blooms.

Although some types of Clerodendrum are extremely invasive, Clerodendrum bleeding heart is a well-behaved, non-aggressive plant that reaches lengths of about 15 feet (4.5 m.) at maturity. You can train Clerodendrum bleeding heart vines to twine around a trellis or other support, or you can let the vines sprawl freely over the ground.

Growing Clerodendrum Bleeding Heart

Clerodendrum bleeding heart is suitable for growing in USDA zones 9 and above and is damaged in temperatures below 45 degrees F (7 C). However, it often regrows from the roots in spring. In cooler climates, it is commonly grown as a houseplant.

Clerodendrum bleeding heart performs best in partial shade or dappled sunlight, but it may tolerate full sunlight with plenty of moisture. The plant prefers rich, fertile, well-drained soil.

Clerodendrum Bleeding Heart Care

Water the plant frequently during dry weather; the plant requires consistently moist, but not soggy soil.

Clerodendrum bleeding heart needs frequent fertilization to supply the nutrients required to produce blooms. Feed the plant a slow-release fertilizer every two months during the blooming season, or use a water-soluble fertilizer every month.

Although Clerodendrum bleeding heart is relatively pest-resistant, it is susceptible to damage by mealybugs and spider mites. Insecticidal soap spray is generally sufficient to keep the pests in check. Reapply the spray every seven to 10 days, or until the insects are eliminated.

Bleeding Heart Vine Pruning

Prune Clerodendrum bleeding heart vine by removing wayward growth and winter damage before new growth appears in spring. Otherwise, you can trim the plant lightly as needed throughout the growing season.

Grow And Care Glory Bower – The Glory Bower (Clerodendrum) is originally from Africa and usually regarded as a greenhouse plant, its climbing stems reaching 8 ft or more. Glory Bower is adorned with rich crimson flowers peeking from white, balloon-like calyxes. Flowering heaviest in the spring, its deep, forest-green leaves are a welcome sight after a long dormant winter. Most are subtropical evergreens from the family verbenaceae. Some are vining, others are large shrubs or small trees.

By pruning in winter, however, it can be trained as a bush or hanging basket plant. The flowers appear in summer among the heart-shaped leaves. In summer it requires high air humidity, good light and warmth; in winter it must be given a rest with infrequent watering and cool conditions.

In summer it requires high air humidity, good light and warmth; in winter it must be given a rest with infrequent watering and cool conditions.

Clerodendrum thomsoniae

Clerodendrum thomsoniae (Bleeding Heart Vine) has long, weak stems – pinch out tips for room display. Allow stems to trail or to twine around an upright support. The leaves have a quilted look.

Clerodendrum trichotomum (Harlequin Glory Bower) is loaded with fragrant cascades of blooms after only a few years, and it attracts a carnival of many colorful bees and butterflies. Clerodendrum trichotmum can grow into a tree, as high as 50 feet, but usually heights of 20 feet or so are more common.

Clerodendrum trichotomum

Glory Bower planting tips

Propagate from the seed in spring at 55-64°F (13-18°C). Remove suckers in fall or spring from trees and shrubs. Root semi-ripe cuttings in summer using bottom heat. Semi-ripe cuttings are cuttings taken from semi-mature wood. Glory Bower grows best with full sun exposure. Shrubs work well in a border, and climbers can be trained over a pergola, trellis, or any other supportive structure. It needs fertile soil to grow well. Apply a balanced liquid fertilizer on a monthly basis during the growing season.

Secrets of success

Temperature: Warm or average warmth. Keep cool (55°-60°F) in winter.

Light: Brightly lit spot away from direct sunlight.

Water: Keep compost moist at all times throughout spring and summer. Water very sparingly in winter.

Repotting: Repot in spring every year.

Propagation: Take stem cuttings in spring.

Pests: Prone to mealybugs, aphids, whiteflies, cankers, leaf spots, and galls.

Plants & Flowers

Common name: Bleeding Heart Vine, Bleeding Glory-Bower, Glory-Bower, Bagflower, Beauty Bush

Family: Lamiaceae

Clerodendrum thomsoniae

Distribution and habitat: Clerodendrum thomsoniae is an evergreen liana growing to 4m (13 feet) tall, native to tropical west Africa from Cameroon west to Senegal. In some regions it has escaped from cultivation and become naturalised.

Description: Clerodendrum thomsoniae is a vigorous twining shrub with striking flowers. The leaves are rather coarse, heart-shaped, up to 13cm (5 inch) long and 5cm (2 inch) wide and coloured deep green with slightly paler vein markings. Flowers, which are produced on wiry flower stalks st stems ends during the spring and summer and early autumn, grow in clusters of 10 to 30. Each flower consists of 2cm (0.8 inch) long, white (or else greenish white), bell-shaped calyx with a scarlet, star-shaped bloom peeping through a split in its tip. The contrast of scarlet and white is highly effective.

Houseplant care: Clerodendrum thomsoniae can grow inconveniently high – 3m (10 feet) or more – but may be kept below 1.5m (5 feet) by having its stem tops pinched out regularly during the growing season; the stems themselves can also be trained around three or four thin stakes in the potting mixture. This species can make an attractive trailing plant when kept under control in a large hanging basket. Although not difficult to grow, it will not flower unless given adequate humid warmth during the active growth period.
At the end of the rest period, as new growth becomes apparent, cut back at least half the previsions year’s growth in order to keep these plants within bounds. Because flower buds are produced on current season’s growth, pruning at this time will encourage the production of vigorous flowering shoots.

Light: Grow Clerodendrum thomsoniae in bright filtered light. They will not flower unless there is a constant source of adequate light.
After pruning, move the plant to a warm, brightly lit location or outdoors if temperatures have warmed sufficiently.

Temperature: Clerodendrum thomsoniae plants will do well at normal room temperatures during the active growth period, but they should be given a winter rest in a cool position – ideally at about 10-13°C (50-55°F). To ensure satisfactory flowering, provide extra humidity during the active growth period by mist-spraying the plants every day and by standing the pots on trays or saucer of moist pebbles.

Watering: During the active growth period water Clerodendrum thomsoniae plentifully, as much as necessary to keep the potting mixture thoroughly moist, but never allow the pot to stand in water. During the rest period water only enough to keep the mixture from drying out.

Feeding: Give actively growing plants applications of liquid fertiliser every two weeks. Withhold fertiliser during the winter rest period.

Potting and repotting: Use a soil based potting mixture. Young plants should be moved into pots one size larger when their roots have filled the pot, but mature plants will flower best if kept in pots that seems a little too small. Quite large specimens can be grown effectively in 15-20cm (6-8 inch) pots. Even when pot size is not changed, however, these Clerodendrum thomsoniae should be repotted at the end of every rest period. Carefully remove most of the old potting mixture and replace it with fresh mixture to which has been added a small amount of bone meal.

Gardening: Clerodendrum thomsoniae plants grow outdoors in warm, sheltered and frost-free areas. If these plants are damaged by light frost, burnt tips and leaves should be left on the plant until spring and then cut away to make way for vigorous new growth.
Clerodendrum thomsoniae plant can be kept pruned into a shrub or given support and allowed to scramble like a vine. This vine-like shrub does not spread much, thus is a good choice for a restricted support like a doorway arch or container trellis and not such a good candidate to cover a fence or arbor.

Position: Clerodendrum thomsoniae will tolerate full sun with adequate moisture but they will prefer partial shade. Best flowering results occur with morning sun and afternoon shade.
Keep these plants protected from strong winds, hot sun and frost.

Soil: Clerodendrum thomsoniae grown in garden like a well-drained soil, rich in organic material. If planted in a garden bed, make sure the soil is well-drained. Dig hole twice the width of the container. Remover plant from container and place into the hole so the soil level is the same as the surrounding ground. Fill hole firmly and water in well even if the soil is moist.

Irrigation: Clerodendrum thomsoniae likes high humidity and a moist, but not soggy, soil. Give it a generous watering regime during growth period. Regular watering will encourages new growth. As the plant grows its thirst grows with it. A Clerodendrum thomsoniae vine that occupies 9m (3 feet) trellis can drink 10l (3 gallons) of water weekly.

Fertiliser: Clerodendrum thomsoniae is a heavy feeder. To produce profuse flowers through the growing season, apply either a slow release-type fertiliser with micronutrients every two months or a liquid water soluble fertiliser with micronutrients monthly. Bloom should continue throughout the season if adequate amounts of calcium are available to the plant. If the fertilizer chosen not have calcium, a separate calcium supplement may be applied. Crushed eggshells stirred into the soil are an excellent organic calcium supplement for plants.

Propagation: Propagate in spring from cuttings 10-15cm (4-6 inch) long. Dip each cutting in a hormone rooting powder and plant it in an 8cm (3 inch) pot containing a moistened equal-parts mixture of peat moss and coarse sand or a substance such as perlite. Enclose the pot in a plastic bag or heated propagating case and keep it at a temperature of at least 21°C (70°F) in a position where it gets medium light. Rooting will take four to six weeks; when new growth indicates that rooting has occurred, uncover the pot and begin watering the young plant sparingly – just enough to make the potting mixture barely moist – and start application of a liquid fertiliser every two weeks.
About four months after the beginning of propagation process, move the plant into a soil based potting mixture. Thereafter, treat it as a mature Clerodendrum thomsoniae plant.

Problems:
Watch for mealybugs and spider mites.
Treatment: Use appropriate insecticides. Alternatively, remove mealybugs with an alcohol­ saturated cotton swab or wash plants with soapy water.

Glasshouse whitefly can be a problem, especially indoors.
Treatment: Successive sprays of insecticidal soaps or white oil will eradicate whiteflies infestations.

Clerodendrum thomsoniae blooms heavily in spring and summer. If it does not bloom much, move it to where it will get indirect light from a south- or west-facing window.

Recommended varieties:
Clerodendrum thomsoniae ‘Delectum’ has rose-magenta flowers in very large clusters.

Clerodendrum thomsoniae ‘Variegatum’ has flowers like those of the main species, but its leaves are pale green at the margins and have light and dark green marbling in the central portion.

Uses and display: Clerodendrum thomsoniae makes an excellent hanging container plant or can be trained on a trellis. It is a non-invasive climber for a fence, pergola or trellis indoor plant for brightly lit conservatory or sunroom bold, eye-catching flowers provide colour for much of the year. This evergreen climbing plant will clothe and decorate the wall, trellis or other support that it grows against. In a sunroom or conservatory it makes a splendid backdrop. For a formal look, grow this plant in a large white wooden conservatory box.
