General Description:
Dryandra is a large genus of 135 species in the Protea family. Their nearest relative is the genus Banksia but, unlike the banksias, Dryandra occurs naturally only in Western Australia (Banksia can be found in all states and one species one even extends its range to islands to Australia's north).
Dryandra fraseri has been cultivated by enthusiasts for many years and has proven itself to be one of the hardier species in the genus. There are three recognised varieties; var.fraseri is widespread over the entire range of the species from Kalbarri north of Geraldton to Cranbrook in the far south-west of the state; var.ashbyi has a coastal distribution in the northern part of the range; var.oxycedra has a very restricted occurrence south east of Geraldton and is regarded as endangered. The differences between the varieties are based on variations in foliage and habit:
- var fraseri...sprawling plant to 1 metre with green or blue-green leaves (up to 100mm long by 15-20mm wide) which are deeply lobed almost to the midrib
- var.ashbyi...low shrub with blue-green leaves which have more crowded leaf lobes
- var.oxycedrus...large shrub to 6 metres with very narrow and elongated leaf lobes
There is another unnamed variety which may be given a botanical classification in the future.
The flowers clusters of D.fraseri are normally bright yellow and around 30-35 mm in diameter. They are conspicously displayed either at the ends of stems or in the leaf axils and are seen in autumn and winter. Some forms of this species have flowers with a distinctly pink colouration.
Although one of the better known of the dryandras, D.fraseri is not grown to any great extent except by Australian plant enthusiasts. It has proven itself to be very reliable in areas where wet, humid summers are not experienced. It tends to become a bit untidy with age but responds well to pruning if required.
Propagation from seed is relatively easy and cuttings are also successful.
| Transfer of Dryandra to Banksia |
A paper published in February 2007 (see below) has proposed that the genus Dryandra be subsumed into Banksia. The paper publishes new names in Banksia for all currently recognised Dryandra species. At this stage ASGAP is retaining Dryandra as a separate genus until it becomes clear whether the published change will be generally accepted by Australia herbaria.
