Loading... Please wait...A native to Western Australia, the Woolley Bush or Adenanthos grow very well in cool to temperate regions of Australia. The Silver Streak variety grow to 3m tall by 2m, creating a dense soft foliage screen. The shrub can be cut into a hedge, and looks best if pruned once a year. The small red flowers are not much of a feature as its soft grey foliage, which really does feel like wool.
