Genus of mainly deciduous but also evergreen trees and shrubs, that comprises more than 140 species. Cultivated mostly for the colour of their foliage and their autumn interest. The leaves are mainly lobed or compound and always arranged in an opposite and decussate phyllotaxy on branches.
Latin name: Acer griseum
They require full sun or slightly shaded sites and humus-rich, well drained soils, neutral or slightly acid soils for a better autumn colour.
Planted as specimen trees, or in groups and rows.
The typical species are propagated with seeds that germinate with difficulty at a temperature
of 15-18 οC (59-64 οF), after cold stratification, while the cultivars are propagated by grafting on the typical species.
Deciduous tree with a spherical crown and dark green foliage that turns a vivid red colour in autumn. It features a heavily exfoliating, reddish-brown bark, that makes it highly ornamental.
