The fresh blossoms and succulent stems of buckwheat have been applied in Europe for the purposes of dyeing wool, &c. The infusion, by the addition of preparations of bismuth and tin, produces a beautiful brown color. From the dried flower bundles, different shades of green are obtained. The Siberian species of wheat, in particular, yields a fine yellow, which upon boiling the wool still longer in the dye, changes into a golden tint, and at length becomes a beautiful yellow.

The best yellow, however, is made by boiling quercitron bark - yellow oak bark - with a small portion of sulpha muriate of tin.
