Cultivars ĭue to its vigor and fall colors of yellows and bright reds, the size being a small tree of 6 metres (20 feet) wide by 6 m tall on average, it suits many for smaller landscapes and for planting under power lines. It is a nonnative invasive species in parts of northern America. It is also valued in Japan and elsewhere as a species suitable for bonsai. ![]() In the UK it has gained the Royal Horticultural Society's Award of Garden Merit. It is often planted as a shrub along borders. Planted on exceptional sites facing south west with consistent moisture and light loamy soils, this tree can grow 3 to 4 feet per year making it a fast grower. It is naturalised in parts of North America. It is the most cold-tolerant maple, hardy to zone 2. Cultivation and uses Īcer ginnala is grown as an ornamental plant in northern regions of Europe and North America. tataricum, which has matte, unlobed or only shallowly lobed leaves. Taxonomy Īmur maple is closely related to Acer tataricum (Tatar maple), and some botanists treat it as a subspecies A. The fruit is a paired reddish samara, 8–10 mm (0.31–0.39 in) long with a 1.5–2 cm ( 5⁄ 8– 3⁄ 4 in) wing, maturing in late summer to early autumn. The flowers are yellow-green, 5–8 mm (0.20–0.31 in) diameter, produced in spreading panicles in spring as the leaves open. The leaves turn brilliant orange to red in autumn, and are on slender, often pink-tinged, petioles 3–5 cm ( 1 + 1⁄ 4–2 in) long. The leaves are opposite and simple, 4–10 cm ( 1 + 1⁄ 2–4 in) long and 3–6 cm ( 1 + 1⁄ 4– 2 + 1⁄ 4 in) wide, deeply palmately lobed with three or five lobes, of which two small basal lobes (sometimes absent) and three larger apical lobes the lobes are coarsely and irregularly toothed, and the upper leaf surface glossy. The bark is thin, dull gray-brown, and smooth at first but becoming shallowly fissured on old plants. It is a small maple with deciduous leaves that is sometimes grown as a garden subject or boulevard tree.Īcer ginnala is a deciduous spreading shrub or small tree growing to 3–10 m (9.8–32.8 ft) tall, with a short trunk up to 20–40 cm (8–16 in) diameter and slender branches. dissertation.Acer ginnala, the Amur maple, is a plant species with woody stems native to northeastern Asia from easternmost Mongolia east to Korea and Japan, and north to the Russian Far East in the Amur River valley.

The shape is variable from a multi-stemmed to single trunked and can be successfully tailored to specific landscape requirements by pruning. It is more shade tolerant than most maples, giving it the potential for spreading into intact forests. Amur maple is a deciduous tree or large shrub in the Sapindaceae (soapberry) family. As a result, it may continue to spread from cultivation into a variety of habitats. Ecological Threat Due to the specie's small size, fragrant flowers and attractive fall foliage (particularly when grown in full sun), Acer ginnala is desirable as an ornamental tree and continues to be sold and planted. The seeds of Acer ginnala are dispersed primarily by wind with the help of winged samaras. Fruit The reddish fruit, which hang on the tree until late fall, have nearly parallel wings and are 0.75-1 in. These flowers, unlike those of most maples, are fragrant. Flowers The yellow-white flowers appear from May-June, after the tree has leafed out, and are borne in long-peduncled panicles. The fall color of the leaves is usually red, but some are bright yellow. This plant leafs out early in the spring. The margins of the leaves are doubly serrate. They are 3-lobed, with the terminal lobe elongated. Foliage The leaves are opposite and 1-3 in.
