What does it look like?

  • Deciduous (occasionally semi-evergreen) open, multi-stemmed shrub up to 3m tall.
  • Stems are bluntly angled, clad in tufts of easily removed soft, woolly hair and becomes lax when long.
  • Thin, willow-shaped leaves are usually hairless above, white or hairy grey underneath, and finely toothed.
  • Distinctive, dense, cone-shaped hanging clusters made up of many fragrant purple or white flowers, from December to February, with orange insides are followed by seed capsules.
