The Garden Under Glass

120 THE GARDEN UNDER GLASS Good varieties of tulips for growing in the greenhouse are : Mon Tresor, Proserpine, Couleur de Cardinal, Rose Gris de Lin, Thomas Moore, Tournesol, Keizerskroon ; and the early varieties, Duc von Thol. A few Darwin or May-flowering tulips might well be tried in pots if space be available, but it would not do to force them very early. Among narcissi we should include the old English double, as also the various forms of Phoenix, Golden Spur, Emperor, Sir Watkin, Princeps and Autocrat. A few also of the polyanthus forms might be included, such as Grand Monarque. The sweet-scented jonquil will be most appreciated. Good hyacinths may be bought more cheaply in their colours than in named varieties, and considering the great price asked for hyacinths I would certainly advise this course. Irises, crocuses and snowdrops are not offen grown in pots, but when they are the same kind of treatment may be afforded them. It must not be forgotten that after forcing most of these bulbs become available for the outside gården, and on that account they should be carefully dried off and be planted out during the summer or autumn, so that if they are somewhat expensive at first they serve a purpose, with few exceptions, for more than one year.
