Rapidly growing, the Royal Frost birch matures to a height of 40 to 45 feet with a canopy spreading up to 20 feet. This winter deciduous tree develops an elegant, upright pyramidal form, showcasing striking white exfoliating bark. Its deep burgundy foliage emerges in spring, transitions to a rich blackish-purple throughout summer, and transforms into a vibrant deep red in autumn. In early spring, it produces subtle pendent catkin flowers that add to its seasonal beauty.
