Primulaceae (Genus comprising from seventy)
A genus comprising from seventy to eighty species of mostly hardy, alpine, perennial, rhizomatous herbs, natives of Europe and temperate Asia, a few American, one or two found in the mountains of Java, and one in the frigid region of South America. Flowers white, pink, purple, or yellow, umbellately or verticillately racemose, very rarely solitary, involucral-bracted, ebracteolate; calyx tubular, funnel-shaped, or campanulate, often inflated or angular, with five persistent lobes; corolla hypogynous, infundibuliform or hypocrateriform, with a short or elongated tube, and a limb of five flat or concaves, spreading or incurved, imbricated lobes. Leaves all radical, usually obovate-spathulate, rarely orbicular and long-stalked, entire, toothed, or rarely lobed. The various beautiful Auriculas have been derived from P. Auricula. Five of the species are natives of Britain, and include the well-known common Primrose (P. vulgaris), Cowslip (P. officinalis), and Oxlip (P. elatior), of our meadows and woods. The species described in the following pages are hardy, except where otherwise stated.
Primulas are charming and exceedingly useful plants, adapted collectively for various decorative purposes and positions under glass, and also in the open air. In them are represented great diversity of habits and growth, some being very dwarf and slow growing, while others develop and flower as large plants in a comparatively short time. Many of the hardy species are excellent subjects for sunny positions on rockwork; but some that are rare should receive special attention, or be kept in pots in a cold frame. Primulas of any description may be successfully grown in pots, if kept in the proper positions and temperatures which the several species and varieties require. The hardy ones may be kept in cold pits or frames throughout the summer, such as those with a north aspect; in winter, they must also be kept cool, and allowed to rest. Damp is one of the greatest enemies to hardy Primulas in winter, but still their roots must never be allowed to become too dry. All the small alpine species and their varieties should have their crowns kept well above the soil, and be maintained in position by placing pieces of sandstone on either side. This provision against damping applies to those grown in pots, in the open border, or on rockwork: it is always advisable to support the--in many instances, tiny--plants in this way. Varieties of the hardy Primrose are well adapted for naturalising in woods or shady places along with the common sort. A quantity of plants for this purpose may readily be raised from seed, a good strain of which should be secured.
Propagation of the species of Primula is most generally effected by seeds. The varieties of any section seldom reproduce themselves true from seed, and these have therefore to be propagated by cuttings or divisions. Careful division sometimes affords a method of increase amongst rare species when seeds are not procurable, and also more frequently amongst others that are commoner. Seeds of the hardy species are best sown, soon after they are ripe, in shallow pots or pans of light soil; the seeds should be thinly covered, and the pots placed in a cold frame, and kept shaded. When the seedlings appear, they should be placed near the glass, and, in due course, pricked out, or inserted singly in small pots of soil similar to that in which the seeds were sown. P. japonica, one of the finest, strong-growing species, succeeds well in pots for greenhouse decoration, and also when planted on rockwork or in the open border. The seeds of this species should be sown when ripe, and the plants, when raised, grown on to flower the second spring following. As they are very vigorous, rich soil and rather large pots should be provided for them after the first winter has passed. If the flowers appear on plants within a year after the seed has been sown, it is not so desirable as when they can be kept back until starting time, after two winters have passed. P. japonica never requires any fire-heat; all the leaves die down in winter, when the pots may be stored in a cold frame, and kept moderately, but not quite, dry. P. obconica, a pretty and very popular plant, is best adapted for pot culture; it flowers, more or less, in a cool greenhouse or conservatory, nearly all the year. Propagated, in spring, by carefully-made divisions, and by seeds. Another Primula well suited for pot culture in greenhouses is P. cortusoides Sieboldii, of which there are several beautiful varieties, all worthy of more extended culture than they at present receive.
Perhaps the best-known Primula is that which is very generally and extensively cultivated for greenhouse and room decoration from autumn till late in spring, namely, the Chinese Primrose (P. sinensis). Of this beautiful and popular species, there are single and double varieties, but plants of the former kind are more easily grown, and more frequently seen in gardens, than are those of the latter. These Primulas are always most acceptable in winter, when their bright and cheerful flowers appear to best advantage, and suggest the return of spring; at the latter season, however, the plants attain their greatest degree of perfection. To keep a succession of the single ones in flower, the first portion of seed should be sown in March, for growing plants in preparation for the ensuing autumn, and other sowings should be made in April, May, and June. Shallow pans are best for the seed; they should be well drained, and filled with light soil, composed chiefly of leaf mould, with a little loam and sand. The surface may be slightly pressed, to make it even, and the seeds must only be very lightly covered; the pans should then be placed in a warm frame or pit, and kept shaded. A pane of glass, laid over the top of each pan, will prevent rapid evaporation, and watering need not then be frequently practised until germination takes place. The young plants should be left in the seed-pans or pots until ready to pot off singly, unless any of them show signs of damping, in which case they are best pricked off at once in new soil, about 1in. apart, and kept shaded for a few days. In about a fortnight, a cold frame will be the most suitable place, as the plants must be kept near the light, and have plenty of air while growing, to insure what is most essential--a compact, sturdy habit. As the soil in small pots becomes filled with roots, shift on into others 5in. in diameter, a size sufficiently large for Chinese Primulas to flower in. For the final potting, an open and rather rich soil is necessary, consisting of two parts loam to one each of well-decayed manure and leaf mould, a little charcoal or sand being added to insure porosity. The pots should clean, well drained, and perfectly dry when used. Ventilation, watering, and shading, are the principal points requiring attention in the general management. Throughout the summer, a slight shading, or screen from the sun's rays, is necessary through the hottest part of the day: a thick or continuous shading is more injurious than beneficial. Liberal supplies of water are required in summer; but towards autumn, and in the winter, it must be carefully administered. A light, airy house, where the plants may be kept near the glass, is best for these Primulas, when in flower, during the winter or spring; and a temperature of from 50 deg. to 55 deg. is better, at that period, than a higher one. In potting, the plants should be inserted so that their bases just touch the soil when the work is completed; the crowns must not be buried, but, if situated too high, they are always tumbling about afterwards.
Double varieties of P. sinensis must be propagated by cuttings, but some of the semi-double forms reproduce themselves from seed. Old plants, after flowering, should be encouraged to start a little growth, when they may be cut up, and each division inserted as a cutting. Some cultivators surround the base of the stems with leaf mould, into which the roots grow, and, when the divisions are made, plants instead of cuttings are already fit for potting off. Double varieties require culture very similar to single ones after they are established, but they will bear a little higher temperature when flowering.
VARIETIES. Of P. sinensis there are several strains which receive separate names, but, for general purposes, distinct, fimbriated white and red varieties are, if kept separate, sufficient. A greater diversity can, however, be procured by purchasing or saving mixed seeds from good, large, fimbriated flowers. The strain is of great importance, as there are so many inferior ones. All vendors of seed, doubtless, endeavour to supply the best quality; but varieties degenerate so fast, and all the inferior ones produce seed so freely, that the reputed quality is not always to be relied on. P. s. filicifolia alba, filicifolia rubra, fimbriata alba, and fimbriata rubra, are those most commonly grown; other sub-varieties of fimbriata are: Alba Magnifica, Chiswick Red, Coccinea, Marginata, Meteor, Scarlet Gem, Village Maid, and Waltham White. Of double varieties, the old Double White is one of the best and most useful winter-flowering plants grown. There are a few double sorts with coloured flowers; they are very useful for cutting, but are not extensively cultivated.

Stems long, straggling, somewhat woody. California, 1884. A pretty rockwork plant.
P. tyrolensis (Tyrol). See P. Allionii.
P. variabilis (variable), of Goupil. A hybrid plant, which not unfrequently occurs wild in Britain, in company with its two parents, the Primrose and the Cowslip. It is often taken for the true Oxlip (P. elatior). P. venusta (charming). fl. purple; corolla thrice as long as the calyx; involucre much shorter than the pedicels; scape glabrous. April. l. ovate, dentate, serrate, or almost entire, glabrous on both surfaces. h. 3in. Hungary, 1833. (B. R. 1983.) P. veris (spring). A synonym of P. officinalis.
P. verticillata simensis (whorled, Simen).* fl. yellow; scape bearing two or three tiers or whorls of flowers, the stalks of which measure some 2in. in length; the whorls provided with spreading, leafy bracts, those in the lower whorls being the largest, measuring 4in. to 5in. long, and 1 1/2in. broad; corolla salver-shaped, with a tube nearly 2in. long, dilated at the upper extremity, the lobes notched. Spring. l. oblong-lanceolate, 8in. to 10in. long, covered with white, mealy powder, especially on the lower surface, irregularly dentate. h. 1ft. to 1 1/2ft. Abyssinia, 1870. A very desirable, greenhouse species. (B. M. 6042.) SYN. P. Courtii.
P. villosa (villous). A synonym of P. viscosa.
P. viscosa (clammy).* fl. rosy-purple, with a white eye, disposed in umbels on viscid scapes; corolla lobes cordate, gashed, the tube twice as long as the bell-shaped calyx. Early summer. l. obovate or sub-orbicular, with closely-set teeth, dark green, covered wtih gladular hairs, and viscid on both sides. k. 2in. to 4in. Pyrenees, 1768. A handsome species. See Fig. 286. (B. M. 14; J. F. A. v. App. 27; L. B. C. 182; R. G. 656.) SYN. P. villosa. P. decora is a slight variety of this species (B. M. 1922; L. B. C. 1480.) P. v. latifolia (broad-leaved). fl. violet, with mealy throat and calyx, fragrant; umbel from one to twenty-flowered. Early summer. l. obovate or oblong, sometimes 4in. long, and nearly 2in. broad, serrately toothed from middle upwards, ciliate, hairy on both surfaces. h. 4in. to 8in. Pyrenees, 1820. (Fl. Ment. 12; R. G. 122.) P. v. pedemontana (Piedmont).* fl. rosy-purple, with a yellowish-white eye, collected into a dense head, on scapes from 2in. to 4in. in height; throat of corolla not farinose. Spring. l. oblong or ovate, obsoletely repand-toothed, with fimbriated margins. h. 6in. Piedmont, 1826. (B. M. 5794.) P. vulgaris (common).* Common Primrose. fl. usually pale yellow, with a flat limb; calyx tube inflated, five-angled; lobes acuminate; umbels sessile, giving the appearance of being solitary. Spring. l. tufted, sessile. h. 3in. Europe (Britain). (Sy. En. B. 1129.) There are numerous garden forms of this species (frequently met with under the name of P. acaulis), a double-flowering one being represented.
