Product Description

Description: Semi-deciduous to deciduous tree up to 30m tall with an open rounded to spreading crown with feathery light green foliage and characteristic green bark. Its spines are straight and paired. Flowers are round, bright yellow and sweetly scented, appearing between September and November. The pod is a small, straight, brown and dehiscent (splitting when mature).

Features of Particular Interest: The lemon – green powdery slightly flaking bark is its most distinguishing feature. The bark peels off in huge thick pieces leaving sculptured patterns on the trunk. The flowers and pods attract monkeys, insects and insectivorous birds. It is extremely fast growing.

Height and Spread: 12m, sometimes reaching 15m, spread 5-8m.
