Acer cappadocicum (Cappadocian maple) is a maple native to Asia, from central Turkey (ancient Cappadocia) east along the Caucasus, the Himalaya, to southwestern China.[2][3][4][5][6]
It is a medium-sized deciduous tree growing to 20-30 m tall with a broad, rounded crown. The leaves are opposite, palmately lobed with 5-7 lobes, 6-15 cm across. The leaf stems bleed a milky latex when broken. The flowers are in corymbs of 15-30 together, yellow-green with five petals 3-4 mm long; flowering occurs in early spring. The fruit is a double samara with two winged seeds, the seeds are disc-shaped, strongly flattened, 6-11 mm across and 2-3 mm thick. The wings are 2.5-3 cm long, widely spread, approaching a 180° angle. The bark is greenish-grey, smooth in young trees, becoming shallowly grooved when mature.[2][3][5][6]
There are three varieties, sometimes treated as subspecies:[4][5]
- Acer cappadocicum var. cappadocicum. Turkey, Caucasus, northern Iran.
- Acer cappadocicum var. indicum (Pax) Rehd. (syn. var. cultratum (Wall.) Bean). Himalaya.
- Acer cappadocicum var. sinicum Rehd. Southwestern China.
The closely related Acer lobelii from southern Italy is also treated as a subspecies of A. cappadocicum by some authors.[5] The eastern Asian species Acer amplum, Acer pictum, and Acer truncatum are also very closely related, and often confused with A. cappadocicum in cultivation.[4]
Cultivation and uses
Cappadocian maple is grown as an ornamental tree in Europe. Many of the trees in cultivation show a strong tendency to produce numerous root sprouts, a character rare in maples.[2][3] The hybrid maple Acer × zoeschense shares this character and probably has Acer cappadocicum as one of its parents.[3]
The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:-
