This plant is a weed of national significance as it has the potential to threaten heritage-listed parks across all regions of Australia. It is widely grown in gardens and is considered a major weed in many areas because of its ability to seed and regenerate in bushland. There are various coloured forms available with flowers from white through yellow to red. Species forms are invasive colonisers. There are sterile cultivars available that do not set viable seed but these can easily be confused with naturally occurring varieties. It is safest not to grow any form of this plant in the garden.

Ornamental low shrub of about 1 m and a similar spread with soft grey–green leaves and dark–red bottlebrush flowers in warmer months. It is reasonably fast-growing and responds well to regular light trimming after flowering to keep it compact and shapely. Like all bottlebrushes, it will attract nectar-feeding birds and small mammals into the garden.

A medium to fast-growing attractive rounded shrub with grey-green leaves. In the garden it may reach a height of about 1.5 m and a spread of 1 m or more. It produces masses of crimson flowers in cooler months that will attract birds into the garden. Reasonably hardy and frost tolerant.

An appealing, sprawling, ornamental shrub that produces large white flowers in profusion over the hotter months. It is an excellent low screening plant, to 2.5 high by 1.5–3 m wide. While it is quite hardy and drought tolerant when established, it may suffer from frosts when young, so some protection in early years is advisable. When grown in poorly drained soils, it may develop some yellowing of the foliage. This can be overcome by improving drainage or planting into raised beds. Pruning will keep it shapely and compact.
