The colours have bsen wonderfully improved of late years, and now the flowers are in many cases as large as those of the sinensis type. Primula Kewensis Another primula which every reader must try, because it possesses a colour hitherto unknown among indoor primulas, is the above. It is yellow and flowers freely, tier over tier, with untiring energy. Like the P. obconica and most other forms of primula, it lends itself to division. To trust wholly to division, however, usually means in time a loss of vigour. Cool treatment following precisely on the lines of P. obconica will suit this beautiful primula. Primula Sinensis Like its variety, stellata, known best as the star primula, this is a gorgeous plant, but more fastidious and requiring more heat than the foregoing; not, be it remembered, that they require much heat. That is not so ; for during the summer months they can well be accommodated in a cold frame and during winter a temperature of 50° will suffice. From February to June the seeds may be sown in a warm temperature. About the germination there is seldom any difficulty. I prefer to see the young plants pricked off into boxes, and only potted singly when they begin to crowd each other. Any good open soil will suit them, provided it be not old potting soil, for they certainly deserve good loam, fresh leaf-soil, and something in the way of manure. A fault with these primulas is that they
