Noteworthy Characteristics

Succisella inflexa, sometimes commonly called devil’s bit, is an upright herbaceous perennial that features globular, Knautia-like, white flowerheads from July to September atop naked stems rising to 30” tall over a spreading clump of long, narrow, green leaves. Each flower head resembles a pin cushion subtended by a ring of bristly involucre bracts. This plant is native to moist to sometimes wet fields, meadows, forest clearings and waste places in Europe, but has escaped gardens and naturalized in parts of North America from Quebec and Ontario south to Michigan and Pennsylvania. Genus name is a diminutive of the genus Succisa which was once included in the closely related genus Scabiosa. Synonymous with Scabiosa inflexa.

Genus name comes from the Greek word succise meaning cut off in reference to the plant roots which appear to be cut off at their ends.

Specific epithet comes from the Latin word inflexus meaning bent inward.

‘Frosted Pearls’ flowers emerge light pink turning white with a slight tinge of blue as they mature.


No serious insect or disease problems.


Not commonly cultivated. Mixes well with ornamental grasses and large-leaved hostas. Good for massing in moist informal areas.
