They occur in masses and provide a colourful display. After flowering, the hard seeds develop in small pods. D.tenuifolia is not well known in cultivation due to its rarity in nature. Propagation from seed is relatively easy following pre-treatment to break the physical dormancy provided by the impervious seed coat. The seed retains viability for many years.
Cuttings strike reasonably well using firm, current season's growth.
