Royal Frost® Birch
This birch has the best from both of its parents. From ‘Whitespire’ it inherited beautiful white bark and resistance to the bronze birch borer. From ‘Crimson Frost’ comes burgundy-red foliage. The combination of two colors makes this an outstanding specimen tree. Much faster growing than ‘Crimson Frost’.
