AURICULA (Primula auricula) , an Alpine plant, which has been an inmate of See also:British gardens for about three See also:hundred years, and is still prized by florists as a favourite See also:spring See also:flower. It loves a cool See also:soil and shady situation. The florists' varieties are grown in See also:rich composts, for the preparation of which number-less receipts have been given; but many of the old nostrums are now exploded, and a more rational treatment has taken their See also:place. Thus Mr See also:Douglas writes (See also:Hardy Florists' See also:Flowers) : " There is no See also:mystery, as some suppose, about the potting, any more than there is about the potting material. The compost should consist of turfy See also:loam four parts, See also:leaf-See also:mould one See also:part, See also:sharp See also:river or See also:silver See also:sand one part, and a few bits of broken See also:charcoal mixed with it. The pots to be used should be from 3 to 41 in. in See also:diameter, inside measure; about I in. of potsherds should be placed in the bottom of each pot, and over this some fibrous See also:turf, from which the See also:fine particles of See also:earth have been removed. The old soil should be shaken from the roots of the See also:plants to be potted; and before potting cut off, if necessary, a portion of the See also:main See also:root. In potting See also:press the soil rather firmly around the roots." Auriculas are best grown in a See also:cold See also:frame mounted on legs about 2 ft. from the ground, and provided with hinged sashes. A graduated See also:stage formed of See also:wood battens 6 in. broad, with a rise of 2 in., should be fixed so as to take each one See also:row of pots, with the plants See also:standing at about 15 in. from the See also:glass; the spaces between the shelves should be closed, while the See also:top See also:board of the back and the front should be hinged so as to be let down when desired for See also:ventilation, the sashes, too, being movable for the same purpose, and also to afford facilities for examining and attending to the plants. This frame should See also:face the See also:north from May to See also:October, and See also:south in See also:winter. No See also:protection will be needed except in very severe frosts, when two or three thicknesses of See also:garden mats may be thrown over the glass, and allowed to remain on until the soil is thawed, should it become frozen. Auriculas may be propagated from See also:seed, which is to be sown as soon as ripe, in See also:July or See also:August, in boxes, kept under See also:cover, and exposed only to the rays of the See also:morning See also:sun.

When seed has been saved from the finer sorts, the operation is one of consider-able nicety, as it not unfrequently happens that the best seedlings are at first exceedingly weak. They generally flower in the second or third See also:

year, a few See also:good sorts being all that can be expected from a large See also:sowing. The established varieties are increased by taking off the offshoots, an operation performed at the See also:time of potting in July or the beginning of August. But some varieties are very shy in producing offsets. The See also:original of the auricula is a hardy perennial See also:herb, of See also:dwarf See also:habit, bearing dull yellowish blossoms. This and the commoner forms raised from seed, as well as one or two See also:double forms, are interesting hardy border flowers. The choice florists' varieties are divided into five classes:—the See also:green-edged, with the margins of the flowers green; the See also:grey-edged, with the green margins powdered with See also:meal so as to appear to be coloured grey; the See also:white-edged, with the mealy See also:powder so dense as to cover the green; the selfs, which have none of the green variegation of margin seen in the foregoing, but are of some distinct See also:colour, as See also:purple, maroon, &c., but have, like the preceding, a white See also:paste surrounding the See also:eye ; and the alpines, which resemble the self s in not having any green marginal variegation, but differ in having a yellow centre more or less dense. The individual flowers of the first three See also:groups of florists' auriculas show four distinct circles:—first the eye or See also:tube, which should have the925 J stamens lying in it, but sometimes has the See also:pin-headed stigma instead, which is a defect; second, the paste or circle of pure white surrounding the eye; third, the See also:body colour, a circle of some dark tint, as maroon or See also:violet, which feathers out more or less towards the edge, but is the more perfect the less it is so feathered, and is quite faulty if it breaks through to the See also:outer circle; See also:fourth, the margin, which is green or grey or white. These circles should be about equal in width and clearly defined, and the nearer they are to this See also:standard the more perfect is the flower. In the See also:group of selfs the conditions are the same, except that there is no margin, and consequently the body colour, which should be See also:uniform in See also:tone, extends to the edge. In the alpines there should be no paste or white surrounding the eye, but this space should be either See also:golden-yellow or creamy-yellow, which makes two subdivisions in this group; and the body colour is more or less distinctly shaded, the edges being of a paler See also:hue. There is besides a group of laced alpines, in which a distinct and See also:regular border of colour surrounds each of the marginal lobes.

The following is a selection of the best varieties cultivated in 1909:- Green-edged.—Abbe See also:
