While this plant has some attractive visual aspects, in generally we recommend selecting an attractive native species instead that will better support local songbird, butterfly, and native pollinator populations. Our top recommendations for native shrubs that have pale silver or white foliage and are more valuable to include in a California landscape include brittlebush, white sage, and california sagebrush.
As its name implies, feathery cassia is a soft textured evergreen shrub growing 3-6 ft. tall and as wide. Foliage is comprised of finely divided gray-green leaves; intense yellow flowers cover the plant in mid winter to early spring.
Native to Australia, feathery cassia grows best in sunny locations on well drained soils and with low amounts of summer water. It tolerates cold to 20°F and can be clipped to maintain smaller sizes. Seedlings of feathery cassia can spread and grow aggressively in gardens.
