Acacia longissima

Scientific NameAcacia longissima
CategoriesNitrogen FixerShrubTreeWattle
Common Name(s)Narrow-Leaf Wattle
FamilyFabaceae, Subfamily Mimosoideae


"Slender shrub or small, spreading tree to 5 m high." (WorldWideWattle ver. 2)


"It usually inhabits the borders of rainforests and it is sometimes locally common. It usually flowers Jan.–May but fruits rarely and so far has been noted as fruiting only during Nov." (WorldWideWattle ver. 2) Our experience with Acacia longissima is mostly in the Jimna Ranges, Qld, where it inhabits Eucalypt forest in proximity to rainforest. Owing to shape and colour, the phyllodes and fruit blend in well with the surrounds and so seed collectors seeking this Acacia will need to be highly observant. Accompanying canopy trees may include Eucalyptus pilularis, Eucalyptus acmenoides, Eucalyptus carnea, Eucalyptus sideroxylon and others. The harvestable seed quanities possible from wild stands of this species are generally quite low.
