A reasonably compact, deciduous, herbaceous perennial, producing deeply lobed, bright green leaves marbled in light green, on stems to 70cm (28in) high. Single slightly reflexed smokey purple flowers appear in spring. While best in sun to partial shade, it is also able to tolerate full shade, making it useful for using in the shady border
