Calocephalus brownii – Silver Bush, Cushion Bush

Calocephalus brownii has a few names that you may recognise a little better, this gorgeous silvery plant is also called silver bush, cushion bush, Calocephalus silvercalos, whimsy silver and even Silver thread plant! It’s proper latin name however is Calocephalus brownii syn. Leucophyta brownii, which is the one we really should all remember. The form of this silver leaved plant is that of a wispy silvery white foliage, small bushing plant which is soft to the touch. The stems grow fairly thick, and it shows small yellow flowers, however most gardeners grow just for the foliage, which looks amazing when planted next to brighter foliage such as Heucheras or darker ornamental grasses. This plant is native to the South coast of Australia, so does best in a well draining soil, full sun, little water and basically left to its own devices. It performs well in low quality soil, and doesn’t need to be given fertiliser.  Generally only lasts a few years, so treat it as such. 

Calocephalus brownii indoors – this plant can be grown indoors with well draining soil and a bright sunny position. Calocephalus red is occasionally for sale, although not as frequently.
