species of ornamental, tall or dwarf, hardy, perennial or 

 rarely annual herbs, natives of Europe, temperate Asia. 

 North America, Mexico, and Chili. Flowers blue, violet, 

 or white, generally showy ; calyx campanulate, five-fid ; 

 corolla shortly funnel-shaped, broadly campanulate, or 

 sub-rotate, with obovate lobes; cymes terminal, loosely 

 corymbose or sub-capitate. Leaves alternate, pinnatisect. 

 Rhizomes usually creeping, thick or slender. The best- 

 known species are described below. They are all 

 perennials, and are of easy cultivation in any good garden 

 soil, but flourish best in a deep, rich, and well-drained 

 loam. Propagated very readily by division.
