Bed 137 in the Garden showcases many species of wattle.

Because this is a rare and endangered species it deserves to be grown much more in cultivation. It is restricted to remnant bushland on shale-derived soils and gravelly clay in western Sydney. Does not readily set seed, but suckers freely from the roots. This was one of the first Australian acacias cultivated in Europe, being grown at Malmaison near Paris in the garden of the Empress Josephine.

Grown in the USA where it is used as a cut flower.

A very ornamental species which will brighten any garden in mid winter.

Propagate from seed or suckers.

Will grow in full sun but prefers semi-shade. Appreciates water during dry periods.

Tolerant of frost.

Not known to be weedy.

Not presently available from the Growing Friends.
