Description and Growing Information

ID CharacteristicIt has very attractive deep green foliage, cream coloured ball shape flowers, with red and spirally pods.
ShapeUpright and wide spread.
LandscapeA specimen or street tree.
PropagationEasily propagated by seed. Place in boiling water for 12-24 hours, (allowing the water to cool during this period), sow before the seeds dry out. The boiling water softens the seed coat and allows quick germination which can vary from 1-4 weeks. Seeds may be sown at any time of year, although spring sown seeds seem 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. For cuttings collect half-ripened lateral shoots and stick in a mix of equal parts sand and peat/compost, place in a heated greenhouse under moist shade; cuttings are slow to root. 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 understock the following spring.
