AUSTRALIAN PLANTS

by Kay Gee

Keraudrenia is an Australian genus consisting of around 10 species. It belongs to the Sterculiaceae family and the similarities with the Guichenotia and Thomasia genera are very obvious.

Few of the species have found their way into cultivation but many delight visitors to WA where desert species contribute to the fabulous wildflower display in winter and spring.

Perhaps the best known of the species is Keraudrenia integrifolia (Common or Purple Firebush). This small shrub to 1.5m is native to inland areas in all states except Victoria and Tasmania. It has rusty coloured stems and narrow leaves with a rusty felt. The pendant buds are mauve and very hairy. They open out into star shaped flowers with mauve calyx lobes instead of petals. They require a sunny location with sandy soil and excellent drainage. These plants are tolerant of frost.

Keraudrenia hermannifolia is a West Australian species with blue/purple flowers and lobed, hairy green leaves. You can see a picture at http://florabase.calm.wa.gov.au/browse/photo?f=223&level=s&id=5022

K. katatona is another WA species, native to the far north. It has grey foliage and purple flowers from autumn to late winter. You can see a picture at http://florabase.calm.wa.gov.au/browse/photo?f=223&level=s&id=19028

K. velutina has long grey green leaves similar to those of Guichenotia. You can see a picture at

Some of the West Australian Keraudrenias are endangered species.

Keraudrenia corrolata, commonly called Velvet Flower, is native to eastern Australia from north of Sydney to the brigalow belt of Central Queensland. The variety K. corrolata var. denticulata is regarded as an endangered species in the Hawkesbury region and other parts of northern NSW. Keraudrenia lanceolata is commonly called Queensland Velvet Flower and is native to central Queensland.

While Keraudrenia's beauty is subtle, its drought tolerance means that it is the kind of plant that may have garden potential in the future with careful selection and research. Let's hope that all the genetic diversity will still be available when that time comes.
