Hibiscus
heterophyllus: is a member of the Malvaceae family. We are probably
more familiar with the exotic Hibiscus species that have been subjected
to decades of breeding and hybridizing than native varieties. Australia is
home to about 35 species. Perhaps, in the future, some of these native species
will be included in breeding programmes. Hibiscus heterophyllus is
known as the Native Rosella, not to be confused with the common name of some
Australian parrots. Hibiscus
heterophyllus is a shrub or small tree with prickly stems. The leaves are
either ovate or 3-5 lobed with a few hooked spines on the lower surface. The
flowers are about 15 centimetres across and may be white, pink, pale or bright
yellow. The flowers also a have a basal purple spot. The flowering period
extends form from July to April. Prune after flowering to prevent the plants
becoming straggly.
Hibiscus
heterophyllus occurs in New South Wales and Queensland, usually in moist
situations in open forest. The species is widely cultivated and was introduced
into England in 1803.
The specimen
illustrated was photographed in Carnarvon Gorge in July 2004. The bright
yellow flowers light up the surrounding bushland.
Propagation is
from seed or cuttings. Selected and interesting forms should be propagated
from cuttings to maintain the desirable characteristics.
The species
name means having different leaves.
PLEASE NOTE:
Hibiscus heterophyllus may cause irritation to people with
sensitive skin.
