Along the sides of railroads and edging the sandy woods, everywhere from Maine to the Gulf, in its season, great bunches of lupine may be seen, patches of blue in the midst of the pretty, conspicuous leaves. (Name from lupus, a wolf, because these plants were thought to consume the fertility of the soil.)
