Browallia.—Very handsome half-hardy annuals; will grow readily from seed in any garden soil, but prefer a sandy one. They bloom in July. Height, 2 ft.
Brussels Sprouts.—For a first crop sow early in March, and in April for succession. Transplant as soon as ready into deeply-trenched, well-manured soil, about 2 ft. apart. Hoe well, and keep clear from weeds. For exhibition and early use sow in a greenhouse, or in a frame over a gentle hotbed, about the middle of February; prick off into a cold frame, gradually harden off, and plant out in May.
Bryanthus Erectus.—A hardy evergreen shrub, which will grow in any soil if the situation is shady and damp. It thrives without any sunshine, but will not endure the constant dropping of moisture upon its leaves from trees. Cuttings strike readily. April is its flowering time. Height, 1 ft.
Budding.—Budding consists in raising an eye or bud from one part of a bush or tree and transplanting it to another part, or to any other plant of the same species. The process is not only more simple and rapid than that of grafting, but many leading nurserymen contend that a better union is effected, without the risk of dead wood being left at the junction. It may be performed at any time from June to August, cloudy days being most suitable, as the buds unite better in wet weather. It is chiefly employed on young trees having a smooth and tender bark. Of the various systems of budding, that known as the Shield is probably the most successful. Make a small horizontal cut in the bark of the stock, and also a vertical one about an inch long, thus forming an elongated T shape. Next select a branch of the current year’s growth on which there is a well-formed leaf-bud. Pass a sharp knife 1/2 in. above the bud and the same distance below it, taking about a third of the wood with the bud. If in the process of detaching it the interior of the bud is torn away it is useless, and a fresh bud must be taken. Now hold the bud in the mouth, and with as little delay as possible raise the bark of the stock with a knife, insert the bud, and bind it on with raffia. When the bud begins to grow the binding must be loosened. To prevent the shoots being torn away by the wind a stake may be tied on to the stock, and the new shoot secured to it by means of raffia. Fruit trees are sometimes budded close to the soil on stocks 1-1/2 ft. in height. The buds are rubbed off the stock as soon as they appear, but the stock is not cut away until the following spring.
Buddlea.—Half-hardy, tall, deciduous greenhouse shrubs, delighting in a loamy soil mixed with peat. They may be grown out of doors during the summer, but need the protection of a house in winter.
Bugloss (Anchusa).—This showy plant, bearing large blue flowers in June, may be increased by division of the roots into as many plants as there are heads, from slips, or from seed sown in the open border in spring. It is popularly known as Ox-Tongue.
