Red Maple Overview

Acer rubrum is a bushy, medium to large, deciduous tree species in the Sapindaceae family. The Latin word 'rubrum' means 'red' and in this context, refers to the fantastic autumn colouration of this Acer's leaves - its common names including Red Maple and Scarlet Maple, amongst others. It is a low maintenance, architectural tree that has many sub-species. This hardy (down to -20C) tree forms a rounded to open crown and it can typically reach 30m in height. Clusters of tiny, red flowers appear in spring, followed by lobed, dark green leaves which have a pale blue-white underside. Foliage is arranged oppositely on branches, and the 5–10cm long and wide leaves have serrated edges. Acer Rubrum likes a sheltered position in full sun and needs well-draining soil for optimal growth. It also prefers an acid soil, which helps to maximise its autumn colour.
