Conval-laria majalis.
Clayey loam, near water, and where the noonday sun is intercepted by shade, suits it best.
Mr. D. Watts communicated a paper to the Regent's Park Gardeners' Society, in 1845, from which the following are extracts: - "Before planting, dig over and well break the ground about nine inches deep, then plant the roots about four inches apart, all over the surface of the ground, giving them a gentle press down with the thumb and finger, and then cover them about four inches thick with the same sort of soil. On forming new plantations of this plant, I select all the flowering buds from my stock of roots, which I plant by themselves, but in the same way as I do the others. If equal quantities of each can be had, there will be equal quantities of flowers for two or three successive seasons, after which they should be all taken up, the roots divided, and replanted in the same way. At the time of replanting, it will be requisite to leave a sufficient quantity undisturbed, for the purpose of lifting, for forcing during the winter months.
Pot them in thirty-two-sized pots, filled to within three and a half inches of the rim with rich loam, upon which the roots are closely placed, and then covered about two inches in thickness with equal parts of leaf mould and sand; they are then well watered, so as to settle the mould about the roots; place them on a shelf near the glass, in a moist stove, or forcing-house, the temperature of which may range from 65° to 75°, and take care that the soil does not become dry. When they are so far advanced that the plants show their heads of flowers, remove them into a warm green-house, still placing them near the glass, until as they advance in growth they are withdrawn by degrees into a shaded part of the house, from whence they are removed to the drawing room as required, their places to be immediately filled with others, which are similarly treated, and thus an ample succession will be kept up. Care and attention are requisite in lifting and selecting the plants for forcing; they require a minute examination to distinguish those that will flower from those that will not, the only difference being that the buds of the former are more round and short than those of the latter." - Florist's Journ.
