Description and Growing Information
Flowering Period
MarchAprilMay
Shape
A spreading and suckering shrub or small tree.
Pests
May be infested with caterpillars, especially of the tortix moth (Cacoecimorpha pronubana). Also subject to attack by scale insects and red spider mites.
Habitat
Grows in sandy, coastal plains, but also in swampy sites and riverbanks to small, rocky hills.
Propagation
Easily propagated by seed placed in boiling water for 12-24 hours, (allowing the water to cool during this period) and then sown before the seeds dry out. The boiling water softens the seed coat and allows quick germination which can vary from one to four weeks. Seed may be sown at any time of year although spring sown seed seems to yield slightly more significant results. Once seedlings have produced their true leaves they may be pricked off into pots and transplanted according to growth rate. Cuttings may also work using half-ripened lateral shoots stuck in a mix of equal parts sand and peat/compost and placed in a heated greenhouse under moist shade; cuttings are slow to root. Selected plants can also be approached grafted onto A. retinoides seed raised stock that is 18-24 months old and about 30 cm in height. Once the graft has taken remove the top growth from the under stock the following spring.
