BREECH. Mostly hardy herbaceous perennials of vigorous growth and broad foliage, suitable for backgrounds of borders and subtropical effects. The acanthus leaf is one of the commonest of art forms. The ornamentation of the Corinthian column is said to have been suggested by A. spinosux. Height 3-4 ft.: spikes 1-1%ft. long;fls. dull white to rose or purplish. Mostly southern Europe.
