Kalopanax pictus
Kalopanax pictus (septemlobus), common name Prickly Castor Oil Tree, is a deciduous tree in the family Araliaceae, the sole species in the genus Kalopanax. It is native to north eastern Asia, from Sakhalin and Japan west to southwestern China. It grows to 30 m tall, with a trunk up to 1-1.5 m diameter. The stems are often spiny, with stout spines up to 1cm long. The leaves are alternate, in appearance similar to a large Fatsia or Liquidambar (sweetgum) leaf, 1535cm 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 2050cm across at the apex of a stem, each flower with 4-5 small white petals. The fruit is a small black drupe. It is cultivated as an ornamental tree for the 'tropical' appearance of its large palmate leaves. Despite its tropical looks, it is very hardy, tolerating temperatures down to at least -40C.
