Description EDIT
A dense, perennial, rounded shrub up to 3 m high with large lemon-yellow flowers with a deep red to blackish centre.
Growing EDIT
It is relatively frost tolerant, requires a moderate amount of water and prefers warm to cooler areas.

It is a relatively fast-growing plant, providing that it is planted in fertile, rich and well-drained soil. Enrich the soil with a considerable amount of compost and organic material. The soil pH should range from mildly acidic (6.1 to 6.5) to neutral (6.6 to 7.5). Prune the shrub towards the end of summer.

This plant can be propagated by way of herbaceous stem cuttings or from seed, which should be sown directly after the last cold period. Allow the seedheads to dry on the plants, then remove them and collect the seed.
Distribution EDIT
Occuts open bush, thickets and forests, often also found along rivers.
Natural distribution stretches from the Eastern Cape in South Africa to tropical East Africa and Madagascar and the Mascarene Islands.
History EDIT
The name Hibiscus is derived from the Greek word for marshmallow.
In addition to being a popular garden subject, Hibiscus calyphyllus is apparently also a source of food in the Okavango Delta, where the flowers are cooked and eaten when there is a shortage of food.
Ecology EDIT
The pollen in the large flowers attracts insect pollinators such as butterflies, which in turn will lure insectivorous birds such as barbets, robins and flycatchers to the garden.

Certain species of moth and butterfly larvae are known to feed on various Hibiscus species. This includes the Arrow Sphinx moth ( Lophostethus dumolinii) and Koppie Charaxes (Charaxes jasius saturnus) butterfly.
