FIG. 279. BRIZA MINOR, showing Habit and small Panicle of Flowers.
B. minor (small).* Little Quaking Grass. fl., spikelets triangular, seven-flowered; glumes longer than the flowers; panicle with hair-like branches. June and July. l. pale green, short, narrow. h. 8in. England (but very rare). An exceedingly pretty little annual or perennial grass. SYNS. B. gracilis and B. minima. See FIG. 279. (S. E. B. 1775.)
B. spicata (spiked). A recent introduction from Brazil, described as being very graceful and quite distinct, having erect spikes about 8in. in height.
BROADCAST. A method of sowing seeds by means of the hand, scattering them over the surface of the ground as equally as possible. It is now superseded, for the majority of garden and field crops, by drilling, which not only economises the quantity of seed used, but greatly facilitates subsequent weeding and thinning out.
BROCCOLI (Brassica oleracea botrytis asparagoides). A cultivated variety of the Cabbage, having the young inflorescence condensed into a fleshy, edible head (see Fig. 280). To grow this popular vegetable successfully, it is necessary to have rich soil of a good depth, in an open situation, where the plants can have plenty of sun and air to keep them sturdy. They succeed the autumn Cauliflower, and are in season from November till May.
Soil. In preparing ground for Broccoli, trench, in the autumn, to the depth of from 1½ft. to 2ft., and during the process work in a liberal dressing of rotten farmyard manure. Ground which has carried a crop of Celery is very suitable for the strong-growing kinds, as, by planting where the Celery rows have been, the necessity of trenching is, to a great extent, obviated. Smaller kinds, however, need to be planted closer in order to obtain a profitable crop.
Cultivation. At the beginning of May, prepare seed beds on a south border, and sow the earlier and sprouting kinds. The later varieties would, perhaps, be best sown in April, but they must not be put in early and allowed to remain too long in the seed bed. Sow thinly, to get the plants as sturdy as possible; and, to prevent clubbing, work in a little soot or wood ashes on the surface of the beds. Care must also be taken to pick off the club excrescences at planting time, should there be any, and to destroy the grub inside. Clubbing is not so frequent in ground which has been well trenched, and where the plants are not allowed to suffer from drought. Showery weather should be selected for transferring them to their permanent quarters. If it is desired that they should succeed potatoes, they may be planted between every two alternate rows, and the latter crop can be removed when ready. Broccoli succeed best where the ground is firm, and not recently dug or manured. Planting with a crowbar is preferable to digging the ground afresh. If grown by themselves, a distance of from 2ft. to 3ft. should be allowed between the rows, and an equal distance from plant to plant. Some of the early varieties will, in favourable seasons, follow the later Cauliflowers, while the latest will not be fit for use until the following spring. The heads should be cut as soon as they are large enough; they will keep good for a week in a cold place, while a day or two might open them too much if allowed to remain on the plants. Broccoli which have to stand the winter are liable to injury from severe frosts, and some method of protection is necessary. Two plans are recommended for both large and small gardens, and either or both may be adopted, as found convenient. The first is to apply a covering of fern or other dry protective material, not using too much, but giving sufficient to break the rays of the sun, which, perhaps, do as much harm as the actual frost. The other plan is to take up the plants as soon as the flowers can be seen, and lay them in under a hedge or wall until required for use. In sheltered positions, or where there are trees to break the force of the wind, the covering with dry litter during severe weather will generally be found sufficient; still, a little precaution in lifting will frequently save a valuable crop. Broccoli should never follow a crop of any other kind of cruciferous plants, particularly Cabbage.
FIG. 280. BROCCOLI.
Sorts. Veitch's Self-protecting Autumn, Purple and White Cape, Grange's Early White, and Snow's Winter White. These are the best for autumn and mid-winter supplies. A good selection for spring and late purposes is Mitchinson's Penzance, Knight's Protecting, Cooling's Matchless, Purple Sprouting, Model, Willcove, Leamington, and Cattell's Eclipse.
BRODIÆA (named after J. J. Brodie, a Scotch cryptogamist). SYN. Hookera. ORD. Liliaceæ. Pretty, slender, hardy, or in some positions only half-hardy, bulbs. The flowers are usually borne in large clusters or umbels; the prevailing colour is blue; coccinea is, however, an exception, the flowers being scarlet. The scape is usually straight and slender, but strong. Leaves from two to four in number, enveloping the part of the scape beneath the surface, and procumbent thereon. Most of them are of easy culture in rich sandy loam; if grown in pots, a mixture of loam, leaf soil, and sand, suits them well. Increased freely by offsets, which should be left undisturbed with the parent bulbs till they reach a flowering state, when they may be divided and replanted in autumn.
