The Tibetan Whitebeam Tree (Sorbus thibetica ‘John Mitchell’) is a mid-sized deciduous tree derived from traditional Whitebeams originating from western China and the Himalayas. Also known as, John Mitchell, this relatively compact tree reaches a height of 15-20 feet (with a 12-15 feet spread). Other varieties of Whitebeams can tower to 60-70 feet (and spread 50 feet wide).This variety is perfect for most informal gardens and makes a stunning focal tree, and can be grown successfully in zones 5 through 7.
This distinctive tree prefers nutrient rich, acidic, well-draining, moist soil. It benefits from full sun but can tolerate light shade. The tree produces white flowers from umbels in late spring amid green leaves with white underbellies, which produce rusty-brown inedible berries much later in the season. The berries are a favorite of wildlife, especially birds. In autumn, the leaves transform into glorious shade of gold, yellow and bronze.
Tibetan Whitebeam can be propagated by cuttings taken from softwood in summer. If pruning is needed, this should occur in early to mid-winter.
