Tree of heaven
About This Species
Tree of heaven (Ailanthus, Varnish tree) is a deciduous tree that became popular in BC with gardeners for its rapid growth and interesting foliage. It is native to China and Taiwan. It produces by seed and by division and can sprout nearly anywhere – it is tolerant to a wide range of environmental condition. It is described as foul-smelling and now considered a weedy, invasive species that crowds out other plants.
How to Identify
Tree of heaven can reach between 20–30 m in height and 10–15 m in width at maturity. Bark is grey and lightly textured.
Flowers are small and white. Fruit is a showy red samara (like a maple’s “helicopter” like winged seeds).
Leaves grow to 50 cm and are divided into oval-shaped leaflets. In the fall, the foliage turns yellow.
