Ragwort, the Common, Groundsel, Sbggram, or St. James's Wort ; Senecio Jacobaca, L. a native perennial plant, growing in meadows, pastures, and on road-sides; and flowering from July to August.

Where this troublesome weed abounds, it is with great difficulty extirpated. The best method hitherto discovered, appears to be either that of plucking it up by the roots, after the ground has been moistened with showers ; or folding it closely with sheep in the winter season ; so that the heavy rains may contribute to its destruction. If the former plan be adopted, it is recommended to pile up the plants thus pulled and cleansed from earth ; to burn them ; and scatter the ashes on the ground ; or, if this cannot be conveniently done, to leave them to rot on, and manure, the soil; as the rankness and stench of this weed prove it to be possessed of saline and fertilizing properties.—Farther, it is said to be more pernicious in meadow, than in pasture land ; for, in the latter it only tends to exhaust the soil ; while, in the former, it communicates to good hay a disagreeable effluvia, and deprives it of its sweet flavour.

If gathered before the flowers expand, and employed in a fresh state, the ragwort imparts to wool a fine green, though not permanent colour. But, if woollen cloth be previously boiled in alum-water, and then in a decoction of these flowers, a beautiful deep yellow shade will be produced. — Dam bouRney states that, by a decoction of the flowers and stalks while in blossom, the wool previously steeped in a solution of bismuth, acquired a very permanent olive-brown colour, displaying a beautiful golden shade.—When young, horses and cows eat this weed ' but, after attaining its full size, when the stems are a yard high, it is refused by every species of cattle.
