Overview

Australia’s classic dwarf bottlebrush: naturally compact, mounding and dense, with blue-green/grey-green foliage and abundant crimson-red brushes. Flowers mainly late spring–summer, with spot blooms in autumn. Ideal for neat low hedges, borders, mass planting and pots; tough and bird-attracting.
