Lemon bottlebrush is a dense, evergreen shrub native to the rocky slopes of southeastern Australia and Tasmania, where it thrives in windswept, exposed terrain. Growing 5 to 12 feet tall with a spread of 3 to 10 feet, this hardy shrub produces distinctive cylindrical, bottlebrush-shaped flower spikes up to 4 inches long that emerge in late spring to early summer. Its narrow, grey-green leaves are accented by soft pink new growth, and it tolerates everything from poorly drained clay to drought conditions, making it remarkably adaptable for gardeners in zones 7 through 10.

The cylindrical flower spikes that give this plant its name are genuinely striking, appearing in shades that complement the grey-green foliage perfectly. It performs equally well in boggy, poorly drained soils or in dry conditions once established, which means you're not locked into one particular garden scenario. Prune after flowering fades and you'll encourage a denser, bushier form that works beautifully as a hedge or specimen shrub.
Lemon bottlebrush excels as a flowering hedge, where its dense upright growth habit and showy late-spring flower spikes create both structure and visual interest. Its ability to handle wind, heat, and poor drainage makes it particularly valuable for difficult sites where many ornamental shrubs struggle.
