Olearia viscosa is common in Tasmania, growing in wet and dry eucalypt forest, from the coast to steep hillsides usually at lower altitudes, although it occurs from near sea level up to 1400m. It is frost tolerant. On the mainland, it is confined to coastal scrub and rainforest margins near Lakes Entrance in Victoria .
Flowering and seeds
Flowering in spring and seed can be collected in spring – summer. Fresh seed germinates easily, with emergence of seedlings in 2-5 weeks after sowing .
