- Elegant white birch
- BBB resistant
- Durable
History shows that landscapers, designers, and homeowners can’t resist the allure of a white bark birch. AVALANCHE® birch will no doubt provide that same draw, combining exceptional smooth white bark with a ruggedness and durability that withstands challenging conditions and resists bronze birch borer. Bark starts out tan, takes on pink tones and then turns that bright, stunning white. Neat emerald green leaves develop golden fall color. Imported from Japan by Ohio’s renown Storrs & Harrison Company in the mid-late 1800s.
