K.rubicunda is a hardy garden plant which is not extensively cultivated except by Australian plant enthusiasts. The species deserves to to be more widely grown and, if given room to spread, will be a long lasting addition to gardens in temperate to tropical areas. It tolerates dry conditions and would be a useful plant for growing on a trellis or pergola. Propagation is easy from seed following pre-treatment to break the physical dormancy provided by the impervious seed coat. The seed retains viability for many years.
Cuttings strike well using firm, current season's growth.
