A striking tree, the leaves of Betula pendula 'Royal Frost' are a rich, dark purple that pops against the white bark. These contrasting features beautifully enhance each other and were achieved by pairing, 'Whitespire' with 'Crimson Frost'. This is an exciting, relatively new variety that was cultivated in 2006.
The foliage is brightest when grown in full sun although grows well in partial shade. The leaves turn yellow-orange in Autumn, making Betula 'Royal Frost' one of the best Birches for variety of colour. It has an upright, spreading habit and can grow to approximately 7 metres in height and 4 metres in width after 20 years.
Seasons of interest: Spring, Summer, Autumn, Winter
Bark: White bark
Foliage: Dark purple leaves turning yellow-orange in autumn

Planting Advice for Betula 'Royal Frost' Trees
Our pot grown 'Royal Frost' Purple Birch trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.
Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree.
Unless it's a multi stem form, we recommend planting Purple Birch trees with a stake and tie kit to ensure the roots are well anchored - instructions are in the planting guide. Finish by watering generously around the base.
Aftercare Advice for Betula 'Royal Frost' Trees
Purple Birch require a good watering regime for a couple of years to establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. Unlike many species, Birch prefer wet soil than dry. Irrigation kits make it easier.
Keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard. To keep the white bark looking its best, you can wash it using water and a sponge.
Pruning Advice for Betula 'Royal Frost' Trees
Established Purple Birch trees do not require pruning and they do not take well to hard pruning. Hard pruning increases light penetration which in turn results in increased soil temperature and decreased moisture levels. Simply remove the lateral shoots to maintain a clear trunk and prune any diseased or damaged branches. Pruning should be carried out in late summer to mid-winter. Purple Birch trees bleed heavily at all other times of the year, especially late winter.
