Most species have finely divided leaves (often aromatic) and clusters of daisylike flowerheads. Some have gray to nearly white foliage.Tanacetum balsamita
Native Europe to central Asia. This weedy, rhizomatous plant is grown for its sweet-scented foliage (used in salads and sachets) rather than its tiny daisies. Leggy stems reach to 3 ft. high; if these are cut back, the gray-green, finely scallop-edged basal leaves can make a nice edging for an herb garden. Divide clumps and reset divisions in late summer or fall.Tanacetum parthenium
Native to southern Europe and the Caucasus. Compact, leafy, aggressive, spreading by volunteer seedlings; once favored in Victorian gardens. Plants are covered in small yellow, white, or yellow-centered white daisies in summer. Leaves have a strong peppery scent that some people find offensive. Varieties range from 1–3 ft. tall.
To propagate, divide the clumps in spring; or sow seeds in spring for bloom by midsummer.
