The Garden Under Glass

THE BEST FLOWERING PLANTS 93 when they should be brought inside. Until this time no flower buds may be allowed to develop. It will be well into October before a füll display of bioom is obtained, but this should last until the end of January. With the old cut-back plants flowering in the summer and the young plants in the autumn and winter we get quite a surfeit of geraniums. Varieties are very numerous, and most of them good. If I must mention a few I would give Ville de Poitiers, Raspail, Hermione and Denmark as doubles, with Dryden, The Ghost, St Louis, Carmania, Gertrude Pearson, The Sirdar and Dr Rothera as singles. Ivy-Leaved Pelargoniums These are more extensively used for outside, but when well growii they form a good feature in the greenhouse. It is essential that they be kept sturdy or they will not flower well. For the amateur’s greenhouse the best form for growing them is undoubtedly in baskets. This is best done by planting two or three well-established plants in each basket and tying them along the outside until it becomes completely furnished. Cuttings rooted early in the year will form useful flowering plants for the autumn. They look well when grown as standards or columns, especially if arranged in a mass with dwarfer plants be-neath. I do not recommend ivy-leaved geraniums for the greenhouse wall, as they do not flower during the winter. In the matter of soil, pinching and housing the culture may follow on the lines recommended for zonals. Scented-Leaved Geraniums These are not largely grown but a few may usually be seen in the amateur’s greenhouse. I have found that the
