Clerodendrum infortunatum, commonly known as glorybower or bail, is a species of flowering plant in the family Lamiaceae. It is native to tropical and subtropical Asia, from India and Sri Lanka to China, Indonesia, and New Guinea. The plant is a large shrub or small tree growing to 5–15 m tall.
The leaves are opposite, ovate-lanceolate to oblong-elliptic, 6–20 cm long and 3–7 cm broad, with a toothed margin. The flowers are borne in loose clusters of 3-12 flowers, each flower white or pale pink with a five-lobed corolla 8-15 mm diameter. The fruit is a drupe 6-8 mm diameter.
The plant is cultivated as an ornamental plant for its showy flowers. It has been introduced to many other areas, including the Americas, Africa, and Oceania.
How to care:
Glorybower is a fast-growing shrub that can reach 15 feet in height. It blooms on new wood, so prune it annually after flowering to keep it compact and encourage new growth. The plant is drought-tolerant once established, but regular watering will keep it looking its best. It prefers full sun but can tolerate some shade.
Water requirement:
Glorybower needs regular watering, especially when young, to establish a deep, extensive root system. Once established, it is quite drought tolerant.
Fertilizing:
Fertilize glorybower shrubs in early spring with a balanced fertilizer before new growth begins.
Pruning:
Prune glorybower shrubs annually after flowering to encourage new growth.
Ideal temperature:
Clerodendrum infortunatum prefers warm temperatures and will not tolerate frost.
Soil type:
Clerodendrum infortunatum grows best in rich, well-drained soil.
Propagation:
Clerodendrum infortunatum can be propagated from seed or cuttings.Seed – best sown as soon as it is ripe. Germination can be erratic but usually takes place within 20 – 60 days at 20°c. When large enough to handle, prick the seedlings out into individual pots and grow them on until large enough to plant out. Root cuttings, 6 – 8cm long usually grow away well.
Division of suckers in the dormant season. Very easy, they can be planted out direct into their permanent positions if required.
