Kalopanax septemlobus (2 to 3ltr)

Kalopanax septemlobus (2 to 3ltr)


Kalopanax septemlobus has a highly exotic appearance with spiny trunk and exotic lobed leaves.


This purchase is to reserve a specimen of 1-2ft in height into into 3rd season with a trunk girth of 1-2cm in a 2ltr root ball.


Kalopanax septemlobus, common names castor aralia, tree aralia, and prickly castor oil tree, 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 in Chinese, eumnamu in Korean, and harigiri in Japanese.


The tree grows to 30 metres tall, with a trunk up to 1m  in diameter. The stems are often spiny, with stout spines up to 1 centimetre long. The leaves are alternate, in appearance similar to a large Fatsia or Liquidambar (sweetgum) leaf, 15–35 centimetres 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 20–50 centimetres 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.


The tree, despite its tropical looks, is very hardy, tolerating temperatures down to at least −40 °C (−40 °F). The plant grows very quickly at first, however slowing in growth rate when reaching around 40 years old.
