Whitespire Gray Birch (Betula populifolia 'Whitespire')

Whitespire Gray Birch (Betula populifolia 'Whitespire') is a compact, heat-tolerant birch known for its brilliant white bark, upright form, and resistance to bronze birch borer. Originally selected by the University of Wisconsin, this cultivar has gained popularity for its adaptability and low-maintenance performance. Unlike many white-barked birches, 'Whitespire' thrives in both cold and warm climates, making it a reliable choice for landscape designers seeking year-round interest and regional versatility.

Distinctive Features

'Whitespire' grows 30 to 40 feet tall with a narrow spread of 15 to 25 feet, forming a pyramidal to oval shape as it matures. Its smooth, chalk-white bark stands out beautifully against darker foliage and remains clean and attractive throughout the year. The foliage is a rich medium green, turning bright yellow in fall. Although commonly grown as a multi-stemmed tree, it can be trained as a single trunk specimen. This birch is widely appreciated for its durability and bright, upright character.
