''Fatsia japonica'' (fatsi, paperplant or Japanese aralia; syn. ''Aralia japonica'' Thunb., ''A. sieboldii'' Hort. ex K.Koch) is a species of flowering plant in the family Araliaceae, native to southern Japan and South Korea. It is an evergreen shrub growing to tall, with stout, sparsely branched stems. The leaves are spirally-arranged, large, in width and on a petiole up to long, leathery, palmately lobed, with 7–9 broad lobes, divided to half or two-thirds of the way to the base of the leaf; the lobes are edged with coarse, blunt teeth. The flowers are small, white, borne in dense terminal compound umbels in late autumn or early winter, followed by small black fruit. The name "fatsi" is an approximation of the old Japanese word for 'eight' (''hachi'' in modern Japanese), referring to the eight lobes. In Japan it is known as ''yatsude'', meaning "eight fingers". The name "Japanese aralia" is due to the genus formerly being classified within a broader interpretation of the related genus ''Aralia'' in the past. It has been interbred with ''Hedera helix'' (common ivy) to produce the intergeneric hybrid × ''Fatshedera lizei''. ==Cultivation and uses== It is commonly grown as an ornamental plant in warm temperate regions where winters do not fall below about -15°C. ''F. japonica'' have been shown to effectively remove gaseous formaldehyde from indoor air.
