Template:Short description Script error: No such module "Unsubst". Template:Speciesbox
Kalopanax septemlobus, common names castor aralia, tree aralia,[1] and prickly castor oil tree,[2] is a deciduous tree in the family Araliaceae, the sole species in the genus Kalopanax. It is native to northeastern Asia, from Sakhalin and Japan west to southwestern China. It is called cìqiū (Script error: No such module "Lang".) in Chinese, eumnamu (Script error: No such module "Lang".) in Korean, and harigiri (Script error: No such module "Lang".; Script error: No such module "Lang".) in Japanese.[1]
Description
The tree grows to Script error: No such module "convert". tall, with a trunk up to Script error: No such module "convert". diameter. The stems are often spiny, with stout spines up to Script error: No such module "convert". long. The leaves are alternate, in appearance similar to a large Fatsia or Liquidambar (sweetgum) leaf, Script error: No such module "convert". across, palmately lobed with five or seven lobes, each lobe with a finely toothed margin.
The leaf lobes vary greatly in shape, from shallow lobes to cut nearly to the leaf base. Trees with deeply lobed leaves were formerly distinguished as K. septemlobus var. maximowiczii, but the variation is continuous and not correlated with geography, so it is no longer regarded as distinct.
The flowers are produced in late summer in large umbels Script error: No such module "convert". across at the apex of a stem, each flower with 4–5 small white petals. The fruit is a small black drupe containing two seeds.
Cultivation and spread
The tree is cultivated as an ornamental tree for the "tropical" appearance of its large palmate leaves in Europe and North America; despite its tropical looks, it is very hardy, tolerating temperatures down to at least Script error: No such module "convert".. The plant grows very quickly at first, however slowing in growth rate when reaching around 40 years old.
The tree has been found growing wild in several US states, including New Hampshire, Connecticut, and Maryland. It is viewed with concern by the US National Park Service[3] and the Maryland Department of Natural Resources.[4]
Culinary use
In Korea, young shoots, called eumnamu-sun, are often eaten as sukhoe (blanched dish).
