I adore this plant, so delicate looking yet so low maintenance. Mine in planted in amended clay soil, receiving afternoon sun. I would describe it as a slow grower. Highly recommend.

An evergreen shrub from Australia.

Has silvery-green, pinnate leaves with linear leaflets that are covered in grey hair. Bears yellow, pea like, scented flowers. Pods are light brown and slender when ripe.

Flowers at various times all through the year if grown indoors.

Loves a well drained soil in sun. It needs a sheltered position as it can be easily damaged by frosts, especially when young.
