About
Betula ermanii 'Daleside' is a deciduous tree known for its ornamental value. This cultivar exhibits a conical growth habit and features smooth, creamy-white bark that peels away in layers from the trunk and branches. The leaves are oval, toothed, and dark green, transitioning to yellow in the fall. In spring, it produces elongated green catkins that mature to a yellowish-brown as the leaves unfurl.
