The Garden Under Glass

THE BEST FLOWERING PLANTS 99 are inclined to toppie over if not correctly potted, while burying the crown will cause the leaves to damp at their base. I would ad vise that the soil be brought fairly well up to the crown, and as a further security that three short pegs be put around the plant rising only about an inch or two above the soil. Primula sinensis requires shading, but will succeed well in a cold frame in the summer if transferred to a warmer structure early in September. Careful watering, no syringing, plenty of space, a moist bottom, liquid manure after good root-hold, pinching out all flower buds till the end of August—these are the items of culture which need most attention. The stellata type flowers more con-tinuously than the older form. A stock of greenhouse plants can scarcely be deemed complete without primulas. Richardia Ethiopica This harsh name, so science has decreed, obscures the well-known arum or calla lily. This plant, indeed, is one which amateurs might well rejoice over, for, being fond of swampy surroundings, it cannot be injured by over-watering. It is a very adaptable plant, and may be grown in different ways. In some districts it is the practice to set the plants out in the open ground during summer and to di vide and pot them up in the early autumn. Others divide them at the time of planting out. Another method much favoured and found equally successful is gradually to dry off the plants after flowering and then to stand them in their pots in some odd corner till the autumn. This is the safer way and the method I recommend on that account, though growers of an experimental turn of mind may well try a few on the planting-out system. Let it, however, be said, by way of caution, that many good
