About Dwarf River Wattle
Acacia cognata is a fast-growing shrub in the Fabaceae family, native to New South Wales and Victoria. It reaches around 1 m tall at maturity, with evergreen and golden foliage. Yellow flowers appear in spring.
Where to grow Dwarf River Wattle
Dwarf River Wattle suits warm-temperate, cool-temperate and Mediterranean climates and grows best in full sun and part shade or morning sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds.
Soil & planting
Most soils suit Dwarf River Wattle provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Dwarf River Wattle is happy on low water, so once its roots are down it needs little supplementary water. As an Australian native, feed it only with a low-phosphorus native fertiliser. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Dwarf River Wattle after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. Overall it is low maintenance.
Using Dwarf River Wattle in the garden
Dwarf River Wattle earns its place for a feature or specimen planting, pots and courtyard containers and a fast screen or informal hedge. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For a cohesive, low-care bed, pair Dwarf River Wattle with other plants that enjoy the same happy on low water and warm-temperate climate. Group three or five together for impact rather than dotting single plants through the garden. It combines naturally with other Australian natives in a habitat or water-wise garden.
