Propagation
Sow seeds when ripe in situ or in a container and place in an open frame. Germination will occur during spring, prick out and pot up and place outside to harden off.

Botanic information
Leaf: The thin textured dark green ovate leaves have 3 to 5 lobes that are finely acuminate at the apex and during autumn turn clear gold-yellow or occasionally reddish before falling. This is a feature of the tree. 

Flower: The small yellow cyathiform flowers are arranged in conspicuous upright corymb that appears on bare stems during early spring.

Fruit: The samara are in pairs, joined at the base with membranous wings that are almost horizontal. They normally persist on the tree throughout winter.

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.
