Botanic information
Leaf: The palmately lobed leaves expand into full size and have 7 to 11 serrated lobes and a red petiole. During autumn the leaves turn a brilliant red before falling. The buds are also reddish, valvate and pubescent at the base.

Flower: The small reddish crateriform flowers are arranged in an upright umbel that becomes pendulous as it matures during late spring.

Fruit: The samara are in pairs and joined at the base with membranous wings that are yellow-green turning reddish-brown with age. The wings are arranged almost opposite and the seed is dispersed by wind.

General information on pruning Acer species 
The Maples normally do not require regular pruning apart from damaged, diseased or dead wood removal and this should be carried out from autumn to winter. Pruning in late winter or spring may result in bleeding of the sap and should be avoided. Remove reverted branches in variegated trees and clean up split bark with a sharp knife and allow natural healing.
