This is a hardy, annual, maritime plant, common to the seacoast of France and Great Britain. The root-leaves spread regularly from a common centre, are heart-shaped, fleshy, smooth, and glossy,—those of the stem sessile, oblong, and toothed on the margin; the stalks are numerous, and from six inches to a foot in height; the flowers are small, white, and produced in compact groups, or clusters; the seeds are small, oval, a little angular, and retain their vitality three years.
Soil, Sowing, and Cultivation.—It succeeds best in moist, sandy soil; and flourishes in shady situations. Sow the seeds in August, soon after they ripen, in shallow drills eight or ten inches apart; and, while the plants are young, thin them to five or six inches apart in the rows. The plants taken up in thinning may be transplanted, and new beds formed if occasion require. The growing crop should be kept free from weeds, and liberally watered in dry weather. In the following spring, the leaves will be fit for the table. Those plants not cut for use will flower in June, and the seeds will ripen in July. The seeds seldom vegetate well if sown late in spring, or during warm, dry weather.
Use.—The radical leaves are used as a salad, and are sometimes mixed with Cress. When bruised, they emit an unpleasant odor; and have an acrid, bitter taste when eaten. The plant is more generally used for medicinal purposes than as an esculent.
SNAILS.
Snail Trefoil. Medicago orbicularis.
From the south of Europe. It is a hardy, annual plant, with reclining steins, compound or winged leaves, and yellow flowers. The pods, or seed-vessels, are smooth, and coiled in a singular and remarkably regular manner. As they approach maturity, they gradually change to a dark-brown color; and, seen from a short distance, have the appearance of snails feeding on the plant.
The seeds are large, flat, somewhat kidney-shaped, of a yellowish-brown color, and retain their powers of germination five years. They are usually sold in the pods, but should be taken out before planting.
Sowing and Culture.—It is propagated by seeds, which should be sown in April or May where the plants are to remain. Sow in drills fifteen inches apart. The plants should be thinned out where they are too close, and kept clean from weeds; which is all the culture they require. They will blossom in July, and the seeds will ripen in autumn.
Use.—Though entirely inoffensive, no part of the plant is used for food. The pods resemble some species of snails in a remarkable degree, and are placed on dishes of salad for the purpose of exciting curiosity, or for pleasantly surprising the guests at table.
