Brachycome (_Swan River Daisy_).--Beautiful little half-hardy annuals bearing cineraria-like flowers that open well in the border in summer. If well watered in autumn and removed to the greenhouse they will continue to bloom during early winter. Sow the seed as for ordinary half-hardy annuals in rich, light mould, covering them sparingly. Bloom in May. Height, 6 in.
Bravoa Geminiflora (_Twin Flower_).--This hardy bulbous plant bears lovely racemes of coral-coloured flowers in July. A rich loam suits it best. Height, 1 ft.
Briza (_Quaking Grass_).--There are several varieties of this ornamental hardy annual grass. Briza Gracillis is slender, and very pretty both in a green and dried state. Briza Maxima bears large and handsome panicles. Each variety should be sown in pots, or on a sheltered bed out of doors, early in spring. Height, 1 ft.
Broccoli.--Requires a heavy, deep, rich soil, and liquid manure during growth. For earliest crop sow thinly in beds early in March, giving a little protection if necessary. Successional sowings should be made to the end of June, to produce a constant supply till Cauliflowers are ready. Transplant, when large enough to handle, about 2 ft. from each other. Keep the ground free from weeds, and earth the plants up as they advance in growth. Sow Purple Sprouting Broccoli in May for late spring supplies.
Brodiaea Coccinea.--Handsome plants for rock-work or the border. On a dry, light, sandy soil, with plenty of sunshine, their gorgeous spikes of brilliant scarlet flowers are very attractive in May. The bulbs may be planted in November, and left undisturbed.
Broom.--Hardy shrubs thriving in almost any soil. Cuttings will strike if planted in sand under glass. (_See also_ "Genista" _and_ "Spartium.")
Broussonetia Papyrifera.--A very effective deciduous shrub, with large, curiously-cut leaves. It likes an open soil, and is propagated by cuttings. February is its blooming time. Height, 12 ft.
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.
