Acer truncatum, the Shantung maple, [2] Shandong maple, or purpleblow maple, is a maple native to northern China, in the provinces of Gansu, Hebei, Henan, Jiangsu, Jilin, Liaoning, Inner Mongolia, Shaanxi, Shandong, Shanxi, and to Korea. [3]

It is a medium-sized deciduous tree growing to 15 metres (49 ft) tall with a broad, rounded crown. The bark is smooth on young trees, becoming shallowly ridged with age. The leaves are opposite, palmately lobed with five lobes, 5 centimetres (2.0 in) to 12 centimetres (4.7 in) long and 7 centimetres (2.8 in) to 11 millimetres (0.43 in) broad, with a 3 centimetres (1.2 in) to 10 millimetres (0.39 in) petiole; the lobes are usually entire, but occasionally with a pair of teeth on the largest central lobe, and the margin is often wavy. The petiole bleeds a milky latex when broken. The flowers are in corymbs, yellow-green with five petals 5 millimetres (0.20 in) to 7 millimetres (0.28 in) long; flowering occurs in early spring. The fruit is a double samara with two winged seeds, the seeds are disc-shaped, slightly flattened, 13 millimetres (0.51 in) to 18 millimetres (0.71 in) across. The wings are 2 centimetres (0.79 in) long, widely spread, approaching a 180° angle. The bark is greenish-grey, smooth in young trees, becoming shallowly grooved in mature. [3] [4] [5] It is drought and heat resistant. [6]

It is closely related to, and often difficult to distinguish from, Acer amplum , Acer cappadocicum , and Acer pictum subsp. mono , which replace it further south and west in China, and in Japan. From Acer cappadocicum it is best distinguished by the shoots which turn brown by their first winter, not remaining green for several years. [5] From Acer mono (syn. A. pictum auct. non Thunb.) it is best distinguished by the larger, thicker (less flattened) seeds. Acer truncatum is very unusual among maples in showing hypogeal germination. [7]

Cultivation and uses

Shantung maple is grown as an ornamental plant in Europe and North America. [4] [5]

A number of cultivars have been selected, including 'Akikaze Nishiki' with variegated leaves, 'Fire Dragon' with very bright autumn colour. [4] The cultivar 'Keithsform' (Norwegian Sunset) is a hybrid between Acer truncatum and Acer platanoides (Norway Maple). [8]

<span class="mw-page-title-main">Maple</span> Genus of flowering plants

Acer is a genus of trees and shrubs commonly known as maples. The genus is placed in the soapberry family, Sapindaceae, along with lychee and horse chestnut. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, Acer laurinum, extends to the Southern Hemisphere. The type species of the genus is the sycamore maple, Acer pseudoplatanus, the most common maple species in Europe. Maples usually have easily recognizable palmate leaves and distinctive winged fruits. The closest relatives of the maples are the horse chestnuts. Maple syrup is made from the sap of some maple species. It is one of the most common genera of trees in Asia. Many maple species are grown in gardens where they are valued for their autumn colour.
