Plant in bulk with 1,800 Japanese White Birch ‘Whitespire’ (Betula platyphylla var. japonica) seeds. This fast-growing, hardy deciduous tree is prized for its striking white bark, graceful branching habit, and brilliant golden-yellow fall foliage.

Native to Manchuria, Korea, and Japan, this pyramidal tree typically reaches 40–50 feet tall with a 15–30 foot spread. Its bright white bark provides exceptional winter interest, while delicate spring catkins appear before the foliage fully develops. Thin spreading branches and slightly pendulous branchlets give it an elegant year-round silhouette.
