Ailanthus altissima

Tree of Heaven

One type of these Asiatic natives, Ailanthus altissima, is widely grown. It grows quickly to 60 feet high in the worst conditions, tolerating city pollution, drought and moist soils. It also resists insect problems. The chubby branches are covered in leaves made of 15 to 30 dark green leaflets that smell unpleasant when crushed. Blooms in large clusters of small yellow flowers. Plant female trees, since male flowers smell awful. Winged seeds self-sow readily, so remove unwanted starts and suckers. Prune in spring. Water during long dry spells.
