Acacia longifolia (Golden Wattle) - A fast-growing bushy evergreen shrub or small tree to 20 feet tall by as wide with 5 to 7 inch long light green leaves (phyllodes) that have prominent parallel veins. The fragrant golden yellow flowers in 1- to 2-inch-long cylindrical clusters appear in winter to early spring along the end of branches.
Plant in full sun and irrigate occasionally to infrequently – this is a drought tolerant plant in coastal gardens, and it is also salt tolerant, so a useful for seaside conditions. It is cold hardy to 20 degrees F.
Golden Wattle is useful as a screen or windbreak; often seen as freeway plantings but this plant should not be planted adjacent to natural areas, particularly near riparian or dune areas as there is potential for this plant to invade these areas. This plant was originally collected along the South-eastern coast of Australia by Joseph Banks, the botanist on the James Cook's exploration of Australia in 1770 and was offered by nurseries in England as early as 1788. It was introduced into cultivation in California by William Walker at his Golden Gate Nursery in San Francisco in 1860. It has naturalized outside its native habitat in numerous locations in the world, becoming invasive in other parts of Australia (Victoria, New South Wales), in New Zealand, South Africa, Spain, Portugal, Brazil and on disturbed sites in California. The name Acacia comes either from the Greek word 'akazo' meaning "to sharpen" or from the Egyptian word 'akakia', a name given to the Egyptian Thorn, Acacia arabica and the specific epithet refers to the long phyllodes. Other common names include Long-leaved Wattle and Coast Wattle.
Information about Acacia longifolia displayed on this page is based on our research about it conducted in our library and gathered from reliable online sources. We include observations made of this plant as it grows in our nursery gardens and in other gardens that we have visited, as well as how the crops have performed in containers in our own nursery field. We will also incorporate comments that we receive from others about this plant when we feel it adds information and particularly welcome hearing from anyone who has any additional cultural recommendations that would aid others in growing it.
