'Euonymus fortunei' from the website Trees and Shrubs Online (treesandshrubsonline.
The revision of Euonymus by Ma (2001) treats E. hederaceus, E. patens, E. kiautschovicus, E. gracilis and their combinations at other ranks in synonymy with E. fortunei, within which no infraspecific taxa are recognised, including the varieties treated Bean. (The Flora of Japan recognises the Japanese endemic var. villosus (Nakai) H.Hara.)
As is the case with other Euonymus species (compare E. hamiltonianus), this broad approach obscures a great deal of the horticulturally valuable variation reflected in Bean’s detailed discussions of taxa since brought into synonymy. Accordingly, we reproduce Bean’s texts largely unaltered, under their original nomenclature, pending a full, revised (and much needed) treatment of the entire genus, to be undertaken when funding allows.
The name E. fortunei, based on Elaeodendron fortunei (1863) is conserved over the earlier E. hederacea (1853).
In its typical state this species, closely allied to E. japonicus, is confined to the mainland of E. Asia, but the Japanese form described as var. radicans is more common in cultivation. The type variety differs in its leaves, which are elliptic to elliptic-ovate, 1 to 21⁄2 in. long, with the veins prominent beneath and also rather thicker in texture than in var. radicans and not so strongly toothed.
Leaves turning crimson-purple in the autumn and remaining so throughout the winter. This is a juvenile clone, of creeping habit, which occasionally develops into the adult form, becoming a large shrub. Said to be an improvement on it is ‘Dart’s Blanket’, raised in Holland.
Raised in Holland, and said to be an improvement on ‘Coloratus’.
Leaves small, grey-green with a golden edge that pales slowly to dull white. Spreading habit, to about 3 ft high. A very pleasing shrub for ground-cover, raised in the USA by Corliss Brothers.
Leaves roundish, to about 11⁄2 in. wide, with a silvery white edge. Erect habit to about 4 ft, becoming a climber when planted against a wall. Of the same origin as the preceding.
This is the adult state of var. radicans, taken off and rooted as so-called ‘tree’ ivies are. It is a low, spreading shrub with no inclination to climb; leaves 1 to 2 in. long, 5⁄8 in. to 1 in. wide, glossy. Flowers greenish, four-parted, five or more crowded at the end of a slender stalk; fruit orange-shaped, greenish white or tinged with red, 1⁄3 in. across; seed with an orange-yellow coat (Rev. Hort., 1881, p. 373, and ibid., 1885, p. 295, with figures).
Leaves shaped as in the preceding, edged with gold aging to creamy white. Raised in Canada.
This curious little plant – a var. radicans in miniature- was introduced from Japan by Prof. Sargent, and sent by him to Kew in 1893. Leaves dull green, with the veins picked out in a paler shade; 1⁄4 to 5⁄8 in. long, 1⁄8 to about 1⁄4 in. diameter; ovate, rounded at the base, blunt at the apex, margin slightly decurved and with a few shallow teeth; distinctly, but very shortly stalked. The whole plant, but especially the young shoots, is densely covered with minute warts. In a young state this plant forms low patches an inch or two high. Afterwards, if near a shrub, it will climb up its stems. When support of this kind is lacking it will form a little pyramid of its own branches, growing erect and clinging together. About 1938, Mr Ernest Brown (father of Mr George Brown, Assistant Curator at Kew) planted a piece of ‘Kewensis’ against the trunk of an oak and found that as it grew upwards it gradually developed into the ordinary juvenile state of E. fortunei var. radicans and pushed branches outwards and above the supporting trunk. But at the base of the trunk the plant was still of the original ‘Kewensis’ form (Gard. Chron., Vol. 108, 1940, p. 146). Eventually, in 1958, the aerial branches flowered. Material from Mr Brown’s plant, showing all stages of development, is preserved in the Kew Herbarium.
Main stems creeping, branchlets erect, to about 10 in. high. The original plant was found growing wild in Japan (The Plantsman, Vol. 4, p. 63 (1982)).
A very vigorous shrub-form of the species attaining 6 ft in height, raised in Canada. Because of its great hardiness, it makes a useful evergreen in regions with severe winters.
A juvenile form whose leaves have a central variegation of yellow. Raised in Canada.
Synonyms
Euonymus japonicus var. radicans Miq.
Euonymus radicans (Miq.) Siebold ex Miq.
Euonymus repens Carrière
A creeping, evergreen, glabrous shrub, rooting as it spreads over the ground, but when trained up house-fronts and such-like places reaching 20 ft or more high; branches minutely warty. Leaves oval or somewhat ovate, ordinarily 1⁄2 to 11⁄4 in. long, 1⁄4 to 5⁄8 in. wide; tapering about equally to the base and to the blunt apex, shallowly round-toothed, dark green and glabrous; stalk 1⁄12 in. long, warty. Flowers and fruits as in E. japonicus, but somewhat smaller.
Native of Japan. So far as I have observed, this euonymus never bears flowers or fruit in what we regard as its typical climbing or trailing condition. It appears to be like the ivy, and when it has arrived at the adult or flowering state alters the character of its growth, and instead of the shoots being slender and trailing they become erect and bushy, and bear flowers and fruit of the same character as those of E. japonicus; the leaves also become larger. As a garden shrub it is extremely useful; it thrives almost as well as the ivy in deep shade, and makes an admirable ground covering in sunny positions also. It may be used as an edging for paths, being of less trouble, although not so neat, as box-edging. It can be increased with great rapidity and ease by simply pulling old plants apart into small pieces and replanting; every bit will grow. In the New England States, where ivy is not hardy, this plant is used for covering the fronts of dwelling- houses.
This appears to be no more than a minor geographical variant, described from a specimen collected in the North Island of Japan near Sapporo and introduced to the Arnold Arboretum from the same area in 1876. It fruits freely and its adult leaves are broad-elliptic to roundish. What is usually seen under this name is the adult, bushy state, which can be made, however, to cover a fence or low wall if trained.
