Overview

Acer rubrum is a medium to large, deciduous tree species in the Sapindaceae family. The Latin rubrum translates to red, this refers to the fantastic autumn colouration of its leaves, the common names Red Maple and Scarlet Maple reference this. This hardy tree forms a rounded 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, leaves are lobed and are broadly hand-shaped, they have serrated edges and measure between 5–10cm long and wide. It has a bushy habit and is hardy to -20 degrees Celsius, plant in a position of full sun for best results, in well-draining soil for optimal growth.
