It grows in almost any soil, but best in a somewhat moist and rich one, and in shaded positions. The climbing or creeping branches do not flower; flowers are produced on erect, bushy branches, appearing on old, high-climbing plants only. Propagation* is by cuttings of half-ripened wood at any time of the year in the greenhouse or in frames, or, in more temperate regions, in the open ground in fall; gentle bottom heat will hasten the development of roots considerably; also increased by layers and by seeds which must be sown soon after ripening and germinate slowly, usually not until the second year. The slow-growing forms, especially the shrubby ones, are often grafted on cuttings of strong-growing varieties, as they do not grow readily from cuttings.

H. glomerulata, DC., belongs to the genus Brassaiopsis and its correct name is B. glomerulata, Hegel {B. speciosa, Decne. & Planch.). A glabrous tree, with large digitate lvs.; lfts. 5-7, oblong-lanceolate, stalked: fls. in long pendulous panicles consisting of long-stalked globular heads of small Ms. S. Asia. H.M. 4804. Gt. 12:411. G.M. 32:367.—H. himalaica. Tobler (H. helix aurantiaca, Andre). High-climbing: pubescence scaly, gray or yellowish, the scales with many rays: lvs. of the sterile branches pinnately lobed with 2-5 lobes or teeth on each side, those of the flowering branches oblong-ovate to oblong-lanceolate, cuneate at the base: fr. yellow. Himalayas. H.H. 1884:84. Var. sinensis, Tobler. Lvs. of sterile shoots entire or 3-iobed, of fertile branches elliptic or elliptic-oblong. W. China. H. japonica, Tobler (H. helix var. rhombea, Sieb. & Zucc.). Not high-climbing: scales of pubescence with many rays: lvs. elliptic-ovate to rhombic-ovate, those of the sterile shoots 3- or rarely 5-lobed, with broad middle lobe and small lateral lobes: fr. black, about 1/3 in. or less across. Japan, Korea- Alfred Rehder.
