Native river rose

Many gardens have a shady, sometimes moist spot and it’s often hard to find a plant that will thrive and flower in such conditions. The native river rose (Bauera rubioides) will grow beautifully in this type of environment. A dense, occasionally sprawling shrub from 30cm to 1.5m high, depending on the variety, the river rose has deep green trifoliate leaves that are closely attached to the stems. It has small bell-shaped flowers that vary from white to mid- or deep pink, with a mass of yellow stamens in the centre. Peak flowering is in spring, with spot-flowers at other times.

The river rose makes a great border or background shrub that also functions as a weed-suppressing groundcover. And it looks good in a medium to large container, such as a half wine barrel. I saw a stunning display at Inala Jurassic Garden on Bruny Island in Tasmania, where a variety called Trial Harbour was growing as a border plant, producing eye-catching pink blossoms down to ground level.

The river rose’s low habit, combined with its attractive flowers and foliage, make it a versatile option from a design point of view. It blends with a range of native and non-native plants, working particularly well with species with broader dark green leaves and purple to pink flowers such as small to medium-sized mint bushes (Prostanthera spp.), and complemented by groundcovers such as fan flowers (Scaevola spp.) and native daisies (Brachyscome spp.).

This very adaptable plant can be found in the wild from Queensland to Tasmania. Its common name is an indication of its natural habitat, where it faces a variety of conditions, from seasonal waterlogging to dry spells. So, while it prefers moist soil, the river rose will also tolerate extended dry periods. It is a good indicator plant that will wilt when it needs moisture and perk up after watering. Its dense habit means it rarely, if ever, needs pruning and a yearly handful of low-phosphorus native plant food will help maintain peak flowering the following year.

This is a largely trouble-free plant in the garden with no serious pests or diseases.

In addition to the species type, there are a number of beautiful cultivars, including ‘Candy Stripe’, which has pink flowers with a white centre, and several double-flowered forms. Look for them at native nurseries and online plant outlets.
