Olearia viscosa, common name "Viscid daisybush", is a large, sticky leafed, woody shrub that grows 2 to 3m high by 1 to 2m wide with white to mauve, daisy flowers in summer. The species prefers moist, well drained, mulched soils in part to full sun. It is mainly found in the damper areas of the Knocklofty Reserve, such as the southern slopes of the summit below and along the Southern Trail. In the home garden it should be pruned after flowering to promote more flowers and a bushy habit.
