About
Banksia viscida, commonly known as sticky dryandra, is a small shrub known only from four laterite hills in semi-arid inland Western Australia. Known until recently as Dryandra viscida, it is thought to be rare but not threatened.
How to grow it
The species is little known in cultivation. It germinates well, but is difficult to establish and slow to grow. It has been grown successfully in loamy soil in northern Victoria, but attempts to grow it in the sandy soils of Perth have failed. Tony Cavanagh and Margaret Pieroni suggest that as a compact shrub with attractive foliage it would be best suited to a small garden. It requires warm, dry weather with near full sun, and heavy well drained soils. It is hardy to drought and frost.
Where it grows
Banksia viscida is known only from four lateritic rises on the border of the Coolgardie and Mallee biogeographic regions; these are Digger Rocks, Middle Ironcap, South Ironcap and Hatter Hill. It occurs there in gravelly soil amongst thick scrub. The area is hot and dry, with mean annual rainfall of 300 to 350 millimetres (12 to 14 in), and up to 90 days above 30 °C (86 °F).
