About Tree of heaven
Ailanthus excelsa, commonly known as Tree of Heaven, is a fast-growing deciduous tree native to Asia. It reaches great heights with a straight trunk and a broad canopy, ideal for large open spaces where its shade is welcome, although its use in gardening is controversial due to its invasive nature. Its compound leaves are very large, and its discreet flowers give way to very decorative reddish winged fruits.
Native range
China and northern Vietnam
Care tips
This tree is extremely adaptable and tolerates a wide range of conditions, contributing to its success as an invasive species. It prefers full sun and well-drained soils, although it adapts to poor and compacted soils. Watering is crucial in its early stages, but once established, it is very drought-tolerant. Avoid planting it near structures or in small gardens due to its large size and aggressive suckering ability.
