HARDY ANNUALS .-See also:Annual See also:plants are those which grow up from See also:seed, See also:flower, ripen seed, and See also:die in the course of one See also:season—one See also:year. They are useful in the mixed See also:garden, for though in some cases they are of See also:short duration, many of them are possessed of much beauty of See also:hue and elegance of See also:form. Annuals may be divided into three classes: the hardy, which are sown at once in the ground they are to occupy; the See also:half-hardy, which succeed best when aided at first by a slight hot See also:bed, and then transplanted into the open See also:air; and the See also:tender, which are kept in pots, and treated as greenhouse or See also:stove plants, to which departments they properly belong. Some of the more popular annuals, hardy and half-hardy, have been very much varied as regards See also:habit and the See also:colour of the See also:flowers, and purchases may be made in the seed shops of such things as See also:China asters, See also:stocks, See also:Chinese and See also:Indian pinks, larkspurs, phloxes and others, amongst which some of the most beautiful of the summer flowers may be found. The hardy annuals may be sown in the open ground during the latter See also:part of See also:March or beginning of See also:April, as the season may determine, for the See also:weather should be dry and open, and the See also:soil in a See also:free-working See also:condition before See also:sowing is attempted. In favourable situations and seasons some of the very hardiest, as Silene pendula, Saponaria, Nemophila, Gilia, &c., may be sown in See also:September or See also:October, and transplanted to the beds or See also:borders for very See also:early See also:spring flowering. Those sown in spring begin to flower about See also:June. The plants, if See also:left to flower where they are sown, should be thinned out while See also:young, to give them space for proper development. It is from having ample See also:room that pricked out transplanted seedlings often make the finest plants. The soil should be See also:rich and See also:light. The half-hardy See also:series are best sown in pots or pans under See also:glass in mil& See also:heat, in See also:order to accelerate germination. Those of them which are in danger of becoming leggy should be speedily removed to a cooler See also:frame and placed near the glass, the young plants being pricked off into fresh soil, in other pots or pans or boxes, as may seem best in each See also:case.

All the plants must be hardened off gradually during the See also:

month of April, and may generally be planted out some See also:time in May, earlier or later according to the season. The class of tender annuals, being chiefly grown for greenhouse decoration, should be treated much the same as soft-wooded plants, being sown in spring, and grown on rapidly in brisk heat, near the glass, and finally hardened off to stand in the greenhouse when in flower.
