A deciduous shrub up to 10 or 15 ft high; young shoots usually without down but sprinkled with pale warts. Leaves oval to ovate, pointed, more or less wedge-shaped at the base, 2 to 6 in. long, half as much wide, dark green, glabrous or slightly downy above, pale and downy (sometimes very much so) beneath, ciliate; stalk 1⁄4 to 1⁄2 in. long. Panicles erect, terminal, up to 8 in. long and 5 in. wide, rather loose; flower-stalks reddish, more or less downy, sometimes glabrous. Flowers pale lilac-pink, white inside, with a fragrance resembling, but not so strong as, that of common lilac. Corolla-tube about 1⁄2 in. long with four lobes spreading sufficiently to give the flower a diameter of 1⁄3 in. Calyx cup-shaped, reddish, 1⁄16 in. long, truncate or slightly toothed, glabrous or downy. Seed-vessel shining, spindle-shaped, 2⁄3 in. long, not downy. Series Villosae. Bot. Mag., t. 8739.
Native of W. China; first described in 1891 from material collected by Prince Henri d’Orléans the previous year. It had been collected a year previously by A. E. Pratt, but did not reach cultivation until 1904, when Wilson introduced it from W. Szechwan to Veitch’s nursery at Coombe Wood. This sending was named S. alborosea by N. E. Brown. In 1908 Wilson again collected it in W. Szechwan and of part of his material Schneider made a new species, viz., S. wilsonii, and identified the remainder as S. tomentella; they are now regarded as one species, the differences consisting chiefly in the degree of pubescence.
In all its forms S. tomentella is very handsome and, like others of the Villosae group, valuable in coming into flower in June after the common lilac and its varieties are past. The often very densely downy undersurface of the leaves is distinctive.

Editorial Note
Treated by Bean as Syringa sweginzowii.
A deciduous shrub up to 12 ft high, with slender, glabrous, purplish-grey young shoots. Leaves of thin texture, ovate-lanceolate or oval-lanceolate, often long and slenderly pointed, sometimes more abruptly pointed, the base tapered or almost rounded, 2 to 4 in. long, 1 to 2 in. wide, dark green and glabrous above, paler and hairy on the chief veins beneath, ciliate; stalk 1⁄4 to 1⁄2 in. long. Panicles terminal, erect, usually 6 to 8 in. long, opening in June, sometimes supported by lateral ones; flower-stalks mostly glabrous, purplish. Flowers fragrant, pale rosy lilac, white inside the corolla lobes. Corolla 1⁄3 in. long, slender-tubed; lobes spreading; anthers yellow, inserted near the top. Calyx truncate or with shallowly triangular teeth, glabrous, purplish. Seed-vessel 1⁄2 in. long, pointed, smooth, shining. Series Villosae.
Native of China; first named in 1910 from a cultivated plant in a private garden near Riga; it must, therefore, have been introduced to Europe early in the century, if not before. It was collected in Szechwan by Wilson for Messrs Veitch in 1904, and he found it again in August 1910 at Sungpan, in the northern part of the same province. It is a very hardy, charming lilac of graceful habit which first came into notice in this country through being exhibited by the Hon. Vicary Gibbs at Westminster on 8 June 1915, when it received an Award of Merit. Messrs Lemoine sent out a lilac which they called ‘S. Swiginzowii superba.’ Except that it has panicles somewhat larger than ordinary, such as might be developed under very good cultivation, it does not seem to differ from the type. The species is akin to S. villosa, but has thinner, smaller leaves and a more slender corolla tube, from which the anthers do not protrude.
The still little-known form of this subspecies described as S. tigerstedtii Harry Sm. was introduced by Prof. Harry Smith of Uppsala in 1934 from W. Szechwan, China. It is a medium-sized shrub bearing erect panicles of very pale pink flowers with a fragrance likened by the collector to that of carnations, but more spicy (H. Smith in Lustgården, Vol. 28–9, pp. 105–10 (1948)). It was introduced to Britain about 1954 and is available in commerce. Its name commemorates C. G. Tigerstedt, owner of the Mustila Arboretum in Finland.
subsp. yunnanensis (Franch.) Jin Y.Chen & D.Y.Hong
Common Names
Yunnan Lilac
Synonyms
Syringa yunnanensis Franch.
A deciduous shrub up to 12 ft high, of rather erect, slender habit; young shoots minutely downy or glabrous, reddish, thinly but conspicuously warty. Leaves oval, oblong-lanceolate or narrowly obovate, tapered at the base, pointed, 11⁄2 to 31⁄2 in. long, 3⁄4 to 11⁄2 in. wide, dull green above, glaucous beneath, glabrous on both surfaces but margined with minute hairs; stalk reddish, 1⁄2 to 3⁄4 in. long. Panicle terminal, up to 8 in. long and 6 in. wide, flower-stalks minutely downy. Flowers fragrant, opening in June. Corolla pale pink, becoming almost white, 1⁄4 to 3⁄8 in. long, 1⁄4 in. across the spreading lobes; anthers yellow, reaching the mouth of the tube. Calyx glabrous, cup-shaped, with very small teeth, reddish. Seed-vessel smooth or with a few warts, 2⁄3 in. long. Series Villosae.
Native of Yunnan, China; first named in 1891 from specimens collected by Delavay; first introduced to this country by Forrest when collecting for A. K. Bulley, 1904–7. It is a pleasing lilac with the same smooth, pale, almost glaucous under-surface of the leaves seen in the Himalayan lilac S. emodi, which species is, however, distinct in its much larger leaves and in the anthers being more protruded. Plants grown at Kew and Aldenham as S. yunnanensis appear to fit the type in every way except that the panicles are quite glabrous.
'Alphonse Lavallée' Lemoine, 1885
Large flowers, lavender blue shaded with pink, from purple buds. One of Victor Lemoine’s first double lilacs, now uncommon.
'Ambassadeur' Lemoine, 1930

'Andenken an Ludwig Späth' ('Souvenir de Louis Spaeth') Späth, Berlin, 1883
Flowers deep wine-red, holding their colour well, borne in slender trusses about 1 ft long. Vigorous, spreading habit. Although nearing its centenary, this lilac has maintained itself against all rivals, and remains one of the most popular of all. A.G.M. 1930.The use in Britain of the French name for this lilac is inappropriate, as was pointed out by the Royal Horticultural Society in 1930. It was suggested that the name might be anglicised to ‘Souvenir of L. Spaeth’ (Journ. R.H.S., Vol. 55, p. 279).
'Audrey' (Prestoniae) Preston, 1927
Trusses conical, dense, about 9 in. long and wide. Flowers light magenta pink outside, almost white within. A.M. 1939.

Flowers large, violet-purple, fading to a bluer tone. Trusses large, not dense.
'Capitaine Perrault' Lemoine, 1925
Flowers large, in wide trusses, rosy mauve. Useful for prolonging the season as it is one of the last to flower.
'Charles Joly' Lemoine, 1896
Flowers dark reddish purple paling to a whitened plum-purple, the recurved segments showing the paler undersides. Erect habit.
'Charles X'
This cultivar, put into commerce in the 1830s, probably derived from the old purple lilac, and was raised in France. What is believed to be the true clone is still offered by nurserymen; it has magenta-purple flowers in conical trusses.
'Clarke's Giant' (Hyacinthiflora) Clarke, 1948
Flowers mauvish pink on the inside, pale lavender outside, about 1 in. wide, in very large, loose trusses. Erect, vigorous habit. A.M. 1958.

'Congo' Lemoine, 1896
Flowers deep purplish red in the bud, paling somewhat when open to a rich lilac-purple, in large, open clusters. Compact habit.
Cultivation and Pruning
The lilacs of this group need full sun or the lightest shade, and thrive best in areas where the summers are warmer than the average. To be obtained at their best they must be given generous treatment. Any soil is suitable except a very acid one, and a deep, stiff but well-drained loam is best of all. A chalky soil is very much to their liking, provided it is deeply dug and well fertilised. A mulch of compost or well-rotted manure helps them, and so too does a dressing of bone meal. They need a minimum spacing of 10 ft, and 15 ft is not too much. An important item in the cultivation of the finer lilacs is the removal of the flower-trusses as soon as they fade, so as to prevent the formation of seed, thereby concentrating the energies of the plant in the new growth and the succeeding crop of flower. This dead-heading may not be practicable once a plant has reached its full height, but should always be done when the plant is young. The lilacs need no systematic pruning, but in order to obtain fine trusses the weaker and superfluous shoots may be cut out at the same time as the old inflorescences are removed. But some modern sorts, especially those of the Hyacinthiflora group, are of vigorous and rather lax habit. These should have their branches shortened by about one-third after flowering, to stop them becoming too lanky. Isolated bushes – and a fine, shapely lilac is an admirable ornament for a lawn – should be trained to a single stem by removing all the lower buds and subsequently the lower branches. However, in North America, where borers are an insect pest, they are better grown on several stems, each arising from ground-level – the vigour and size of the plant being maintained by cutting out the oldest shoots in sequence. As the lilacs of this group form no terminal bud, and naturally fork their branches every year, some pruning and training is at first needed to get a tree-like example.Young lilacs should be treated with patience, as some years may pass before they produce trusses of the characteristic size, shape and colour. The flower-buds of newly planted lilacs should always be removed. Old plants that have grown out of shape or lost vigour respond very well to hard cutting, which should always be done in winter or early spring.
'Diplomate' Lemoine, 1930
Put into commerce at the same time as the similar ‘Ambassadeur’, this seems to be uncommon in the trade. The small flowers are slaty blue from deep rosy pink buds, freely borne in open trusses.
'Edith Cavell' Lemoine, 1916
Flowers large, from cream-coloured buds. Panicles large and rather lax.
'Edouard André' Lemoine, 1900
Carmine pink in the bud, opening rosy pink, in broad, open trusses.

Flowers semi-double, light pink, in long trusses; buds rich purple. A fine new variety, introduced to this country by Messrs Notcutt.
'Elinor' (Prestoniae) Preston, 1928
Flowers in dense panicles about 7 in. long, Magenta Rose in the bud, opening pale lilac-pink outside, pale violet inside. A.M. 1951; A.G.M. 1969.
'Esther Staley' (Hyacinthiflora) Clarke, 1948
Flowers vivid carmine-red in the bud, opening a pleasant shade of bright pink. Vigorous, erect habit. A.M. April 25, 1961. A.G.M. 1969.

'Etna' Lemoine, 1927
Buds dark claret-red, opening rich purplish red. Late.
'Firmament' Lemoine, 1932
Flowers near-blue, from pink buds, medium-sized. A charming lilac, in the same style as ‘Ambassadeur’ and ‘Diplomate’.
'Floréal' (Nanceana) Lemoine, 1925
Flowers in rather dense trusses about 10 in. long, light lavender-purple. A spreading shrub, flowering freely in May. Lemoine distributed it originally as ‘S. henryi Floréal’. Mrs McKelvey pointed out to him that as a hybrid between S. × henryi and S. sweginzowii it could not be regarded as a variety of the former, to which he replied: ‘Les catalogues d’horticulteurs n’ont pas la prétention d’etre des documents botaniques, et je ne désire pas changer ce nom.’ (McKelvey, The Lilac, p. 108).
'Fountain' (?Swegiflexa) Preston, before 1948
This is believed to be a cross between S. reflexa and the original clone of S. × swegiflexa, sent out by Messrs Hesse in 1935. If so, it is a back-cross and certainly seems to be near to S. reflexa. It makes a large bush, with drooping panicles of pink flowers in May.
'General Pershing' Lemoine, 1924
Flowers of variegated appearance, lilac-pink mixed with paler pink and light violet.
'Guinevere' (Josiflexa) Preston, before 1938
Trusses about 9 in. long and wide, conical, drooping at the tip. Flowers purple in the bud, opening lilac-purple and fading to a pinker tone. This is the type of S. × josiflexa.
'Hiawatha' (Prestoniae) Skinner, 1934
Flowers in rather short, broad trusses, deep reddish purple in the bud, paler on opening. Low, spreading habit. It is earlier flowering than the Prestoniae hybrids raised by Miss Preston herself. It is recorded that in selecting seedlings Miss Preston chose those in lighter shades, while Mr Skinner favoured the darker-coloured sorts.
'Isabella' (Prestoniae) Preston, 1927
Flowers pale lilac-purple outside, almost white within, in trusses about 1 ft long, dense. This is the type-clone of S. × prestoniae, described by Mrs McKelvey in her monograph and named by her in honour of Miss Preston. A.M. 1941.
'Jan van Tol' Van Tol, Boskoop, c 1916
Flowers snow-white, about 1{1/4} in. wide, in long, drooping panicles. Corolla-segments narrow, widely spaced. The result of a cross between ‘Marie Legraye’ and ‘Mme Lemoine’.
'Katherine Havemeyer' Lemoine, 1922
Flowers large, at first lavender-purple, fading to a pinker tone. Trusses dense, broadly pyramidal. One of the finest and most widely grown of lilacs. A.M. 1933. A.G.M. 1969.
'Kim' (parentage uncertain) Preston, before 1948
Flowers mallow-purple, in broad panicles about 10 in. long. A.M. 1958.
'Lamartine' (Hyacinthiflora) Lemoine, 1911
Flowers about 1 in. across, pinkish mauve, opening towards the end of April. A tall erect bush. This was one of a batch of hybrids between S. oblata var. giraldii and various cultivars of S. vulgaris raised by Emile Lemoine and put into commerce in 1911 (his father Victor Lemoine died in that year at the age of almost ninety). ‘Lamartine’ was planted at Kew in 1912, and received an Award of Merit when shown from there on April 26, 1927. According to the raiser himself, these hybrids did not prove popular with gardeners. Perhaps their lanky habit and early flowering told against them.
'Lucie Baltet' Baltet, before 1888
Flowers flesh-pink in open trusses. A charming lilac, now uncommon but represented in the Kew collection. Mrs McKelvey considered it to be ‘one of the loveliest of the single lilacs’.
'Maréchal Foch' Lemoine, 1924
Carmine-pink buds, opening pinkish mauve and ageing to lilac pink. Large, well-formed trusses. Its tall and narrow habit, as well as its early flowering suggests some Hyacinthiflora influence in its makeup, though, like the preceding, it is classified as a pure S. vulgaris.double pale flowers
'Maréchal Lannes' Lemoine, 1910
Flowers large, more or less double, in broad-based clusters, violet with an infusion of pink.
'Marie Legraye' Mme Legraye (?), before 1879
This old variety was once much used for forcing, and is the parent of many other whites. Flowers ivory-white from yellowish buds. Anthers conspicuous (considered to be a defect in a forcing lilac). Panicles rather narrow and lax.
'Massena'
Flowers with very concave lobes, deep reddish purple. Spreading habit. A.G.M. 1930.
'Maud Notcutt' Notcutt, 1956
Flowers flat, with broad segments, about 1 in. wide, well displayed in shapely trusses about 1 ft high, carried well above the foliage. Habit fairly upright. According to the raisers the cut sprays last well in water. A.M. 1957.
'Michel Buchner' Lemoine, 1885
Flowers pale rosy lilac, in tall trusses.
'Miss Ellen Willmott' Lemoine, 1903
Flowers opening from greenish buds, pure white, hose-in-hose, with broad lobes. Trusses long, open, pyramidal. A.M. 1917. It is usually listed in catalogues as ‘Ellen Willmott’.
'Mme Antoine Buchner' Lemoine, 1909
Flowers hose-in-hose, deep vinaceous purple in the bud, opening soft carmine-rose tinged with mauve. Trusses long and open. A lovely, softly multi-coloured lilac. A.G.M. 1969.
'Mme Charles Souchet' Lemoine, 1949
Flowers large, in broad trusses, near-blue, borne very freely. Possibly a derivative of the Hyacinthiflora group, as it flowers in early May.
'Mme F Morel' Morel, 1892
Flowers reddish purple in the bud, opening light violet-purple, in very large clusters.
'Mme Felix' Felix and Dykhuis, 1924
Flowers in shapely, erect panicles. Raised from ‘Marie Legraye’. A good lilac for forcing.
'Mme Lemoine' Lemoine, 1890
Flowers large, more or less hose-in-hose, in erect, compact trusses. Very free-flowering, even when young. A seedling of ‘Marie Legraye’, crossed with a double lilac. F.C.C. 1897; A.G.M. 1937.
'Monique Lemoine' Lemoine, 1939
Flowers hose-in-hose, in broad trusses. A.M. 1958.
'Mont Blanc' Lemoine, 1915
Flowers from greenish buds, very large, in unusually tall and broad conical trusses.
'Mrs Edward Harding' Lemoine, 1922
Flowers semi-double, purplish red, rather quickly fading to pink. Usually considered to be the best double red. Tall growing. A.G.M. 1969.
'Olivier de Serres' Lemoine, 1909
Flowers light violet shading to a pinker tone, in large trusses. Strong growing, but not flowering freely when young.
'Paul Thirion' Lemoine, 1915
Flowers likened by Mrs McKelvey to large double violets in form, carmine in bud, opening rosy red, fading to lilac pink, in dense, broad trusses. Late flowering (after ‘Mrs Edward Harding’). A.G.M. 1969.II Hybrids of the Villosae SectionThe first crosses between members of the section Villosae were made in France late in the 19th century, and a few later by Lemoine (see under S. josikaea), but none of those that were put into commerce attained much popularity and only ‘Floréal’ is mentioned below. Those best known in Britain were raised in Canada and belong for the most part to the Prestoniae group (see S. × prestoniae) or to the similar Josiflexa group (S. × josiflexa, see under S. josikaea). The Prestoniae group is the larger by far of the two, with about 100 named cultivars, but the amount of variation in this group does not justify such a multiplication of names. Although the parentage of most is known, some of the later cultivars were raised from open-pollinated plants, and could therefore have more than two species in their parentage. The flowers of these lilacs, with the long, slender tube and narrow limb characteristic of the section, render the group as a whole very distinct from those deriving from the common lilac. This, and their privet-like scent, may account for the fact that they have not yet won general popularity. They are of easy cultivation in any good soil and attain mostly a height of 10 or 12 ft and as much in width. Unless otherwise stated they flower in June. They are easily propagated by cuttings.
'President Grévy' Lemoine, 1886
Flowers deep pink in the bud, opening lavender blue with a paler margin. Clusters large and pyramidal. A.M. 1892.single dark flowers
'Primrose' G Maarse, Aalsmeer, Holland, 1915
A sport from ‘Marie Legraye’, with primrose-yellow flowers. A weak grower. A.M. 1950.
Propagation
Most lilacs of this group can be propagated by means of half-ripe cuttings, or by soft-cuttings in a mist unit, but the young plants develop slowly. It is of more interest for the private gardener to know whether the plants he buys are on their own roots or grafted. Propagation by layering has long been practised by British growers and is gaining favour on the continent and in the United States. The advantage of having the plant on its own roots is obvious, but its price is inevitably higher than one that is grafted or budded. Plants on common lilac stock grow well and are said to give better blooms than ‘own-root’ plants, but the disadvantage is that, unless a watch is kept, the variety in time becomes overwhelmed by suckers; if it is not known in advance that the plant is grafted then the case is worse. With privet as the stock the scion does not grow so well nor last so long, if it has to rely for the privet’s roots for its sustenance, but plants produced by modern methods are supposed to be planted with the graft union well below the surface of the soil, the purpose of the privet’s roots being simply to sustain the plant until the scion has struck its own roots.The following selection comprises most of the common lilacs available in Britain, and all those that have received awards from the Royal Horticultural Society. The colours of the lilacs are notoriously difficult to describe, partly because they are impure, and none the worse for that, and partly because they change so much in hue and tone as the flower ages. Susan McKelvey, in her splendid treatment of this group, often devotes five lines to describing the colour of a single cultivar, using the Ridgway colour chart. But she admitted that these detailed specifications were intended only for verification, and stressed that tone, i.e., the degree of saturation, is more important than hue. In the following summary account, the cultivars, apart from the whites, are arranged in two colour-groups – those whose flowers are in the paler shades of near-blue, lavender and pinkish mauve, and those in which the colour is more saturated. The lilacs in the first group assort together amicably. The dark lilacs need more careful placing.single white flowers
'Réaumur' Lemoine, 1904
Flowers deep reddish purple, shaded with violet. Late flowering. Vigorous, bushy habit.
'Sensation' De Maarse, Boskoop, 1938
A remarkable lilac, quite unlike any other. The flowers a rich vinous red, edged with white, in tall trusses. A plant at Kew produces a branch-sport with white flowers.double dark flowers
'Souvenir d'Alice Harding' Lemoine, 1938
Flowers warm white, hose-in-hose, in tall trusses. Useful for its late flowering, at the end of May or in early June.single pale flowers
'Vestale' Lemoine, 1910
A fine, vigorous lilac, bearing its flowers in long, well-filled rigidly erect trusses. A.M. 1931.double white flowers
