Adenanthos 'Silver Haze' (Silver Haze Woollybush) - A medium large upright growing shrub to 6 feet tall and nearly as wide, but that can be kept narrower by pinching and selective pruning. It has beautiful silvery soft gray needle-like foliage and small red flowers that peak out in spring. It looks similar to the form of Adenanthos x cunninghamii that we grow but is upright growing and is denser and hardier than Adenanthos sericeus.
Plant in full sun in a well-drained soil and give very little to occasional irrigation. Hardy to at least 28°F but ultimate hardiness has not been tested. Avoid fertilizers with Phosphorus. This should prove to be a good specimen plant or for use as an informal hedge that is good for attracting hummingbirds and other wildlife with foliage useful in cut flower arrangements.
This plant was first accessioned by the UC Santa Cruz Arboretum in 1998 as UCSC#98.7 and was beautifully planted in their Rock Garden. It was selected as a 2015 University of California Santa Cruz Arboretum Koala Blooms Australian plant introduction and we have been growing it ever since. See our Koala Blooms Page for a list of all of the introductions from the UCSC Arboretum.
