OUTDOOR PLANTS IN GREENHOUSE 125 of its fragrance. Large plants may be obtained by pro-pagating from cuttings in the autumn and growing them along under warm conditions. I have obtained standard plants four feet high, with bushy heads, by adopting this method, but quite respectable plants may be got from spring 'propagation. Six-inch pots will be quite large enough in which to flower them. Good varieties togrow in pots are Lord Roberts and. Madame de Bussey. Kochia Tricophylla.—Offen called the mock cypress, this is a very pretty foliage plant which towards autumn changes to a beautiful reddish tint.

Lobelias.—Both double and single, they make very pretty edging plants in the greenhouse if grown in 3-inch pots. They may be rooted in spring and potted up in April or May. I prefer the double form for this purpose. In the following spring these plants are useful for pro-viding cuttings for the beds and borders. Some very promising plants I have even moved on to 6-inch pots and they have amply repaid the trouble. Mignonette.—Success with mignonette cannot be guaranteed. A system which has brought me more success than any other is to make up some good soil containing plenty of mortar rubble and fill some 5-inch pots to within an inch of the rim. The space thus left is filled with fine sandy soil such as is used for seeds and cuttings. In this the seeds are sown and put into a cold frame and shaded until germination. The seedlings are thinned early, and in due course, when the plants have grown a few inches and are going away strongly, a move is made into 7-inch pots in which fine stuff for the con-
