Appearance
It is an evergreen liana growing to 4 m tall, with ovate to oblong leaves 8–17 cm cm long. The flowers are produced in cymes of 8-20 together, each flower with a pure white to pale purple five-lobed calyx 2.5 cm in diameter, and a red five-lobed corolla 2 cm long and in diameter.
Naming
The plant was named at the request of Rev. William Cooper Thomson, a missionary and physician in Nigeria, in honor of his late first wife. This plant was very popular during the mid 19th century under the name "beauty bush". It lost favour only when its unusual culture conditions were forgotten. Specifically, its root system must be partially submerged in water most of the time, and it wants very good light.An unambiguous common name is bleeding glory-bower; terms like "glory-bower", "bagflower" or "bleeding-heart vine" are also often encountered but can refer to any of the roughly 400 species of "Clerodendrum". In some regions it has escaped from cultivation and become naturalised.
Cultural
It is grown as an ornamental plant for its decorative two-coloured flowers. With a minimum temperature of 10–13 °C, in temperate areas it requires shelter and a frost-free environment. This plant has gained the Royal Horticultural Society's Award of Garden Merit.References:
