CORN-MARIGOLD: A genus of the polygamia superflua order, belonging to the syngenesia class of plants; and in the natural method ranking under the 49th order, Compositae. The receptacle is naked; the pappus marginated, or consisting only of a border; the calyx hemispherical and imbricated, with the marginal scales membranaceous. There are 19 species, of which the following are the most remarkable: 1. The ferotinum is a native of North America. The roots of this plant creep far under the surface, and send up strong stalks more than four feet high, garnished with long sawed leaves ending in points. These stalks divide upward into many smaller; each being terminated by a large, white, radiated flower, which appears in the end of August or September. 2. The coronarium hath been long cultivated in the gardens on account of the beauty of its flowers. flowers. It grows to the height of three feet, with a single upright stalk divided into numerous branches, garnished with pinnated leaves, and crowned with elegant compound flowers of different colours and properties. The varieties are, single and double flowers of a cream colour; yellow; yellow and white; brimstone-coloured; fistular, or quilled; or those with finely jagged leaves, and flowers of all the above colours and properties. All the varieties begin flowering in July; the flowers are exceedingly numerous, and exhibit a constant succession of full bloom till November; and both single and double are succeeded by abundance of seed.

3. The putescens is a native of the Canary islands. It rises with a shrubby stalk near two feet high, dividing into many branches, which are garnished with pretty thick succulent leaves, of a greyish colour, cut into many segments. The flowers come out from the wings of the leaves, growing upon naked footstalks singly, which greatly resemble those of chamomile. There is a succession of flowers on the same plant for the greatest part of the year, for which it is chiefly esteemed. This plant will perfect seeds in Britain when the seasons are favourable.

Culture. The first kind multiplies very fast by its creeping roots, and will thrive in any soil or situation. The second may be raised in abundance from seed, either in a hot-bed or warm border, in the spring, for transplanting; also by cuttings and slips of their branches in autumn. The latter method is practised only for the propagation of the fine doubles, for an early bloom the following summer; and the best time to perform it is in September, or early in October. Cut off at that time a quantity of the robust side shoots, from three to six inches long, without flowers; divest them of the lower leaves, and plant many of them together in large pots, within an inch or two of their tops, and two or three inches apart, give some water, and place them in the shade during the hot weather: by the end of October they will be rooted, when the pots are to be removed either into a greenhouse or garden-frame, for the winter; but the latter is the most eligible, where they may enjoy the full air in mild weather, and have occasional shelter from frost. In April they may be transplanted singly into borders, and some in pots. The plants thus raised will flower a month or six weeks sooner than succeeding summer than those raised in the spring from seed; but as they soon become barren, it is proper to have always a quantity of plants raised from the seed. The third sort may be raised either from seeds or cuttings, but requires to be sheltered in the greenhouse in winter.
