HIMALAYAN or EVERGREEN FLOWERING ASH Fraxinus griffithii (This plant is not on the Australian Noxious Weed List.) Himalayan Ash and Evergreen Flowering Ash are the common names for Fraxinus griffithi, a small dense tree grown by local councils as a street tree because it does not need lopping if grown under power lines. A small, evergreen tree that grows to 7 metres (21ft) with a spread of 3 metres (15ft), this tree tolerates most soils and prefers an open, sunny position. It has compound leaves consisting of multiple leaflets forming a very dense, compact crown of dainty fern-like foliage. Masses of white flowers in Spring are followed by persistent, winged seed. Frost and drought tolerant, this tree is often found in inland gardens.
