It is native to northeastern [[Asia]], from [[Sakhalin]] and [[Japan]] west to southwestern [[China]]. <br /> <br /> 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 1 cm long. The [[leaf|leaves]] are alternate, in appearance similar to a large [[Fatsia]] or [[sweetgum]] leaf, 15-35 cm across, palmately lobed with five or seven lobes, each lobe with a finely toothed margin. <br /> <br /> 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.<br /> <br /> The [[flower]]s are produced in late summer in large [[umbel]]s 20-50 cm across at the apex of a stem, each flower with 4-5 small white petals. The [[fruit]] is a small black [[drupe]] containing 2 [[seed]]s.<br /> <br /> ===Cultivation===<br /> It is cultivated as an [[ornamental plant|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 -40°C. Some concern has been expressed in the northeastern [[United States]] that it is becoming an [[invasive species]] there, seeding freely into natural woodlands.<br /> <br /> {{commons|Kalopanax septemlobus}}<br /> [[Category:Araliaceae]]<br /> [[Category:Invasive plant species]]</div>
