The VENETIAN SUMACH, R. cotinns, though a native of Southern Europe, is so hardy a shrub as not to be injured by the frost of our winters, and is a familiar plant in our gardens, being cultivated for the very singular and ornamental appearance of its elongated, feathery fruit-stalks, which, combined with its blue-green leaves, have led to its common name of SMOKE PLANT. Both root and stem have been used for dyeing a yellow, approaching to orange, the colour obtained being, however, somewhat fugitive. The leaves are largely used for tanning.
