Isopogon formosus growing at UCSC Arboretum

Isopogon formosus

An upright evergreen shrub that grows up to 6′ tall and 4′ wide. Crowded along the stem, the dark green divided leaves are 1 to 2 inches long with rounded segments and sharp tips and look a bit like tiny green deer antlers – new growth is somewhat reddish and slightly hairy. Rounded heads of showy, purplish-pink flowers with yellow styles cluster at the terminal ends of branches during the late winter and spring with oval cones produced after bloom. May not have too many blooms.

Isopogon formosus is generally found growing close to the coast.

Cultivation Notes

Best in full sun in a well-drained soil with only occasional irrigation. It is a drought tolerant plant but also sensitive to phosphorus so be careful about fertilizing this plant. Hardy to about 20 degrees F. Light pruning can improve shape of plant but be careful not to prune into hard wood as hard stems are not likely to resprout. This plant is not often browsed by deer.
