Cutleaf Teasel

Dipsacus laciniatus

Summary 10

Cutleaf Teasel (Dipsacus laciniatus) is a biennial or sometimes monocarpic perennial forb native to Europe. The plant grows as a basal rosette for a minimum of one year then sends up a tall flowering stalk and dies after flowering. Length of time in the rosette stage depends on the amount of time needed to acquire enough resources for flowering to occur. Flowers are cream or white seated in dense woody heads with spiny, awned bracts at the base. The floral bracts are generally shorter than the head and wider than Common teasel. Fruits are a four-angled achene, containing a single seed. A single plant can produce over 2,000 seeds. Rosette leaves are conspicuously veined, vary from somewhat ovoid in young plants to large oblong leaves that are quite hairy in older plants. Stem leaves are simple, opposite, broad, feathering lobed, prickly, and clasp the stem forming cups.

Origin/Habitat 11

Cutleaf Teasel is native to Europe where dried flowerheads were used to raise the nap on woolen cloth and roots were believed to have medicinal properties. It prefers moist soil conditions with direct sun such as fens, riparian corridors, wetlands, irrigation ditches, swales, and roadsides. It can also tolerate drier upland sites such as dryland pastures, abandoned fields, meadows and woodlands, but is not as common there.
