Bocconia frutescens.—A vigorous-growing Mexican shrub, 3½ ft. to nearly 6 ft. high, with few and very brittle branches, large, sea-green, handsome leaves, and greenish flowers. Very effective when placed on grass-plats, either in groups, or as isolated specimens. It requires a somewhat warmer climate than ours to thrive well, though it is sometimes seen in fair condition in the London parks. A mixture of free sandy loam and peat, well-drained ground, and an airy position are necessary. Multiplied by sowing in a hotbed in spring, and may be placed out from June to the end of September. It is difficult to propagate it by cuttings.
*Brassica oleracea crispa.—A handsome kind of cabbage nearly 4 ft. high, with elegantly-cut arching leaves, the divisions of which are finely curled or frizzled. In autumn and winter it may be advantageously employed in the embellishment of winter-gardens, the leaves being at their best during that part of the year.
A still more striking subject is B. o. palmifolia, which attains a height of 6½ ft., and bears its leaves near the summit of the stem, having quite a palm-like appearance in the end of the summer and in autumn. This kind might be used with good effect in various positions, as its “cabbage” character is not so evident. The fact of their being cabbages prevents many people from using these really ornamental plants.
The variegated Kales have been much employed and with a very good result in the winter-garden at Wardie Lodge in Scotland and in other places: they lose their beauty early in spring. “To keep them dwarf and compact, and to bring out their fine colours,” say Messrs. Stuart and Mein, “we sow at the beginning of March thinly. After the plants are a moderate size, we transplant them into a poorish soil, in an open space of ground, but not too closely together. They remain there until they are wanted for use, when they are removed at any time to the winter-garden. We plant out into our beds in November, and keep the heads with their foliage close to the ground. We cut off all the lower rough leaves, leaving the rich-coloured head or centre, which in all weathers will be found to stand up neat and trim, even in bright frosty weather. As the plants are thus much reduced in size, they can be planted much closer in the beds. We may add that, as in other hybrids, worthless plants will occasionally make their appearance: these we discard. No plants should be selected for the beds except those showing pleasing shades of colour.”
Brexia madagascariensis.—A handsome shrub with a slender erect stem (which sometimes attains a height of 25 ft. or 30 ft. in its native country, but with us is seldom seen more than a fourth of that), clothed with alternate, leathery, long, rather narrow, light-green leaves, nearly or quite smooth at the margin. It is one of the tropical stove-plants that have stood well in the open air from June to early in October, but very few places can spare it for this purpose. It requires ordinary stove culture during winter and spring, and should only be placed out after having made a strong growth, and having that growth hardened off. Madagascar.
