    Nursery contributed plant descriptions

    C. sieberi is a compact shrub to about 3' and occurs naturally at high elevations in Australia. The leaves are needle-like and the flowers are like creamy to pale yellow bottlebrushes. This is a frost-resistant species and tolerates snow! Plant in a protected, sunny, well-drained location. Prune after flowering.

    Yet another very hardy bottlebrush, this from southeastern Australia, found growing along creek beds and tolerant of both wet and dry conditions. This fountain-like shrub with fine-textured, narrow leaves can be pruned to maintain a dense structure or allowed to grow to its expected height of 6 ft or so. This form has tight chartreuse, 'bottlebrush" flowers in spring, often repeated in summer. Best in sun to dappled shade. Frost hardy to upper USDA zone 7.

    Evergreen foliage and deep red bottle brush flowers are two important characteristics. Drought tolerance is the number one. Tough and easy.

    A cold hardy Aussie with 3" creamy-yellow bottlebrush flowers in early summer. This evergreen has a twisting picturesque habit that just gets better with age. Sun and drought tolerant and abhorred by deer. Occasional rebloom in fall. Lots of sun, good drainage.
