Crimson King is a popular purple-leaved form of the Norway Maple species Acer platanoides.

The pale green flowers tinged with red appear first in spring, closely followed by the large characteristic 5-lobed dark purple leaves.

The tree is attractive all year-round, but is particularly impressive in the autumn, when the leaves turn yellow and crimson (especially in areas with sunny days and cold nights).

Crimson King makes a striking tree on its own, and is also very effective when planted as a contrast alongside other maples with green foliage.

Leaves may not be present during winter, and we may prune some shoots to fit the delivery carton. Size may vary during the season and between batches. The container (if supplied) is only used for transporting the tree, which should then be planted out in the garden or in a much larger patio planter (not all species are suitable for patio planting).

How to grow

Crimson King is a fast growing maple, likely to reach 5m within 10 years and continuing to grow thereafter.

This is a versatile tree. It prefers an open sunny situation but will cope with some shade. It is a popular street tree, on account of its fairly upright growth and tolerance of polluted environments. It is also a good choice for cold or exposed situations.
