An evergreen bush of dense habit, usually 3 or 4 ft high, sometimes much taller. Leaves mostly in a cluster towards the end of the shoot, aromatic when crushed, usually 3 to 4 in. long, 34 to 114 in. wide, pale or yellowish green, narrowly obovate or oval, thickly specked beneath with transparent glands; leaf-stalk short, stout. Flowers in terminal panicles 2 to 3 in. long, male and female flowers normally on different plants, fragrant, 13 in. across; petals usually four, sometimes five, dull white. Stamens four or sometimes five in the male plant, absent or very much aborted in the female. Fruits globular, or depressed at the top like an orange, bright red, 13 in. wide. Bot. Mag., t. 8038.

Native of Japan, the Ryukyus and the Philippines, with variants as far North as Sakhalin and the southern Kuriles; perhaps also of China and Formosa. Cultivated at Kew as long ago as 1838, this species did not obtain any general attention from horticulturists until it was introduced from Japan by Fortune in 1861 to Standish’s nursery. It received a First Class Certificate when exhibited in fruit in 1864, and was then named S. oblata by Moore, under the impression that the plant now known as S. reevesiana was the true S. japonica. But the acclaim with which the Japanese skimmia was first greeted faded away when it was found that the plants sent out did not bear the expected beautiful fruits. A few knowledgeable gardeners were aware of the dioeciousness of S. japonica but it was not until Dr Masters published his study of the skimmias in 1889 that it came to be generally realised. Even Charles Noble, Standish’s former partner, confessed in a letter to Masters that he had never had fruits off his “S. oblata” and had never heard of male plants, though they had been available, as S. fragrams and S. fragrantissima, for many years before ‘Foremanii’. – See below, under .cv. ‘Fructo-Albo’. – under this name Messrs Hillier offer an attractive white-fruited clone of dwarf habit.


It later emerged that the plant in question must have borne hermaphrodite flowers in that year, since no other skimmia was in flower with Standish at the same time. In later years it bore only female flowers, but in the meantime another plant of the original batch had flowered, which was male and was named S. fragrantissima in 1867. The origin of the male plant named S. fragrans by Carrière in 1869 was not stated, but some of the plants brought from Japan by Fortune were auctioned by Standish in autumn 1864 and it must have been one of these that the nurseryman William Bull exhibited as S. fragrans in the following year.

So far as is known, no plant of S. japonica is constantly hermaphrodite but it is likely that most females produce a few flowers in which the stamens are fertile. The mere presence of stamens in female flowers is of no significance, since close examination will show that these usually have abortive anthers.

From the Supplement (Vol. V)

See Philip Brown’s survey, referred to above, for numerous cultivars of this species which he has found in gardens but which are not at present in general commerce, though stocks are being built up by one nurseryman and will be released in due course. Some of these are already in cultivation at Kew.

† cv. ‘Bronze Knight. – Put into commerce by Messrs Waterer, this is a male clone with flowers similar to those of ‘Rubella’, but with glossier, dark green, more sharply pointed leaves.

cv. ‘Nymans. – Philip Brown considers this to be the best berrying clone for general planting.

cv. ‘Rubella’. – An improvement on this is ‘Ruby Dome’, not yet in general commerce, which will also serve as a good pollinator for ‘Nymans’. Producing little pollen, ‘Rubella’ is not satisfactory for this purpose (op. cit., pp. 243-4).

cv. ‘Veitchii. – It is very likely that plants in commerce as ‘Foremanii’ are really the true ‘Veitchii’.

S. × foremanii – The original account (1881) of the breeding of this skimmia could be misinterpreted. Knight gave the parentage of the original cross as S. japonica × S. oblata. But at that time the first name was in general use for S. reevesiana, which had been mis-identified as S. japonica by Lindley and others, while S. oblata was the name applied to the true S. japonica. However, it is arguable that the name S. × foremanii, although accepted by Rehder, is not properly established, being unsupported by any description. There is therefore much to be said for taking up the next available name for S. japonica × S. reevesiana, which is S. × rogersii Masters, and this is the name used by Brown in his study.

The hybrid cultivars raised by Rogers at the Chandlers Ford nursery were propagated, but cannot now be identified. The two clones distributed by Messrs Hillier as ‘Rogersii’ and ‘Rogersii Nana’ derive from plants raised by that nursery from the original Rogers’ clones in the 1920s. The first is a low-growing female with undulated leaves and a large, many-flowered, rounded inflorescence. The name ‘Rogersii’ for this clone is obviously incorrect, implying as it does that it derives from the original Rogers cross described by Dr Masters. Brown uses for it the name S. × rogersii ‘Nana Femina’. The other Hillier clone (‘Rogersii Nana’) is a male of dwarfer habit, less twisted leaves, and rounded heads of solid-white flowers. The cultivar ‘Helen Goodall’ is of interest as an example of a self-sown, first generation hybrid between the two species (Brown, op. cit., pp. 234-5).


A free-fruiting female clone, first exhibited from Nymans in 1934. Leaves mostly oblanceolate, obtuse or bluntly pointed; petioles tinged with red.


See under S. × foremanii.


A bushy shrub to about 4 ft high. Leaves darkish green, elliptic to oblanceolate, mostly 3 to 4 in. long (to 5 in. in some seasons), acute or subacute at the apex (rarely obovate and obtuse); petioles dark red. A male clone. Flowers very fragrant, pink in the bud, borne in a fine panicle about 3 in. long and 2{1/2} in. wide at the base; peduncles and rachis deep bronzy red, rendering the inflorescences conspicuous long before the flowers expand. Petals and stamens four (S. rubella Carr.; ? S. intermedia Carr.; S. reevesiana f. rubella (Carr.) Rehd.; S. japonica ‘Rubella’, Journ. R.H.S., Vol. 87 (1962), p. 328).This skimmia was introduced to France from China in 1865 by Eugène Simon and to Britain before the end of the century. Its taxonomic position is uncertain, but it seems to agree better with S. japonica than with S. reevesiana, under which it was placed by Rehder. In flower, ‘Rubella’ is the finest of the skimmias, and received an Award of Merit in 1962. It needs a half-shaded position and will flower from every terminal bud even under a dense canopy, provided the soil is not too rooty. There are other males in commerce. One, sent out as ‘Fragrans’, may not be the skimmia originally named S. fragrans but it is a fine ornamental, dwarfer than ‘Rubella’, with unusually glossy leaves and also differing from it in having no trace of a red infusion in any part.

var. repens (Nakai) Ohwi

S. repens Nakai

A northern and montane variant of dwarf stature, sometimes prostrate. Cultivated plants perhaps referable to this variety are erect growing, but with small leaves and of dense habit.


As described by Carrière in 1874 this had very thick and leathery leaves, oval or obovate-elliptic, roundish at the apex, to about 4 in. long and 2 in. wide. Female. This may have been introduced by J. G. Veitch, who was in Japan at the same time as Fortune, but no reference has been found to a Veitchian introduction. ‘Veitchii’ has been said to grow 4 ft high and 6 ft wide, but no authentic plant has been seen.All these forms are easily increased by cuttings, and for the purpose of obtaining fruits one male need only be grown to, say, six females. In order to secure a crop of berries it is advisable to fertilise the flowers artificially. It is necessary, of course, to transfer the pollen from the male to the female, and this is usually done by taking some fluffy material (a rabbit’s tail or camel-hair brush is often used) rubbing it over the male flowers as soon as the pollen is loose, and then dusting over the female flowers with it (the latter are easily recognised by the prominent ovary and stigma, and the abortive stamens). In some districts bees or other insects will do the business themselves, but it is safer to do it by hand. S. japonica grows well in the neighbourhood of towns, but does not, in my experience, fruit freely there, even with artificial fertilisation.S. × foremanii Knight – Sometime in the 1870s the Scottish nurseryman Foreman made a cross between S. japonica and S. reevesiana at the Eskdale Nurseries, Dalkeith. Only one female was raised, and this he pollinated with the best of the male seedlings. The resulting second generation hybrid was exhibited at the Spring Meeting of the Caledonian Horticultural Society in 1881 and received a First Class Certificate (Florist and Pomologist 1881, p. 70).There can be no doubt about the hybridity of the 1881 S. foremanii. But seven years later Foreman staged an exhibit at the R.H.S. Show, December 11, 1888, consisting of numerous pot-grown skimmias of his own raising, these too called S. Foremanii and awarded a First Class Certificate. But the parentage of these was given by the raiser as ‘S. oblata [S. japonica] × S. fragrans’, which, if correct, meant that he had simply fertilised a female S. japonica with pollen of the same species. This prompted a reader of the Gardeners’ Chronicle to ask ‘Did you ever hear of a “hybrid” between a bull and a cow ?’ Dr Masters, who was investigating the skimmias at this time, suspected hybridity in the specimen sent to him by Foreman, largely on the grounds that some of the fruits were obovoid. He described this skimmia as having yellow-green oblanceolate or lanceolate leaves about 3 in. long and {3/4} in. wide, tapered at each end, with reddish petioles; inflorescence many-flowered; berries scarlet, depressed-globose or pear-shaped (Gard. Chron., Vol. 5 (1889), p. 553). Despite his suspicions, Masters placed this skimmia under S. japonica as ‘Foreman’s Variety’. He seems to have been unaware of the earlier account of the undoubted hybrid mentioned above, otherwise he might have interrogated Foreman more closely. Whether any of the Foreman skimmias have been perpetuated vegetatively up to the present time it is impossible to say. Judging from cultivated plants and herbarium specimens, Foreman’s name has been or is associated with three or four different skimmias, none of which agree with Masters’ description. One characteristic of Foreman’s variety (F.C.C. 1888) was that the flowers were as numerous in each panicle as in male forms and consequently just as well-scented as well as producing very large trusses of fruit (up to forty or so berries in each), when fully fertilised.The account of Foreman’s exhibit published in the horticultural press prompted W. H. Rogers of the Red Lodge Nurseries to inform Masters of a new skimmia that he had raised about 1877, when his “S. oblata”, i.e. S. japonica, fruited for the first time. His letter, quoted by Masters, is somewhat obscure, but it appears that the plants he sent out as S. Rogersii were seedlings of the fruiting S. japonica, not a clone. The plant of which he sent a spray to Masters was, however, almost certainly a hybrid between S. japonica and S. reevesiana and accepted as such; the fruits were coloured as in the latter species, but squarish and depressed at the top (Gard. Chron., Vol. 5 (1889), p. 553). The flowers were described by Masters as structurally hermaphrodite, which merely means that the organs of both sexes were apparently fully developed, not that the plant was actually self-fertile. As in the case of Foreman’s skimmia, the plants under the name ‘Rogersii’ are not uniform. The name S. × foremanii var. rogersii (Mast.) Rehd. is based on the plant described by Masters.
