The tender Oxalises or Wood-Sorrels, are deserving of more attention from those who have sunny frames or unheated greenhouses, or even a sunny window, where these flowers can open, for all are sun-lovers. They like a light, rather sandy soil and may be planted in autumn or early spring about two inches deep. They are too numerous to detail, but I may name the following as all worth growing, although the list might be considerably extended. Arenaria, violet-purple; articulata, mauve; Barrelieri, yellow; elegans, purple; hirta, red; valdiviensis, yellow; variabilis, white or red; and versicolor, white and red. Those named among the hardy bulbs can also be grown under glass.
Although generally grown as greenhouse bulbs, the Phædranassas, or Queen Lilies, may be grown in mild districts as frame bulbs, by cultivating them in rather heavy soil, keeping them as dry as possible in winter, and covering the glass of the frame with some canvas or a mat. Some succeed with them in the open, but they there need a position below a south wall and to have some protection in times of severe frost. They are also suitable plants for the greenhouse, where they can be grown in pots and rested in winter. They have umbels of pretty, reflexed flowers, and grow about one and a half feet high. The most suitable for frame cultivation are chloracea, yellow, and sweet-scented; schizantha, vermilion, yellow, and green; and ventricosa, yellow. They may be planted in spring about five inches deep in a frame, or six inches if in the open.
Although the two Pancratiums named below are hardy in the milder parts of these islands, it is more prudent to treat them as plants which need frame cultivation throughout the greater portion of Britain. A warm, sunny border under a south wall is the place for them in the open garden, and in frames it is desirable to give them a similar position. They should be planted with the neck about a foot deep in the open and two or three inches less when in a frame. They belong to the Amaryllis family and have charming white flowers. The hardiest and most easily grown is P. illyricum, but P. maritimun has finer flowers. They like a light soil, and plenty of water while in growth.
