Betula pubescens (Downy Birch) Seeds
Zone 2 to 6.
Often confused with Betula pendula (silver birch) with which it shares the same geographic range, the Downy birch is native to the cooler climates of Europe and Asia.
The tree is upright with elegant, drooping branches. The leaf stalks are downy and this feature provides the tree with its common name. The downy birch can tolerate wetter soils than the silver birch. It thrives in cooler, northern areas and can be short lived in warmer climates.
Tree does best in a sunny site but do not let soil dry out too much.
