Purslane, the Common, or Portulaca oleracea, L. is a tender exoticplant, which is annually raised either on a hot-bed, or warm border, for culinary purposes : it is propagated from seed, and forms an excellent ingredient in summer salads, but is improper in the winter, on account of its cold and moist nature. -The juice of this plant is sharp, and slightly saline, so that it produces laxative effects, when taken in sufficient quantity.—There are two varieties of the oleracea ; one having deep green, and the other, yellow leaves; both of which, however, are produced from the same seed.
