Aromatic perennial. Stems 30-150 cm, branched above. Leaves pinnatipartite to pinnatisect, glabrous to sparsely hairy, glandular-punctate; lower cauline leaves more than 5 cm, petiolate, oblong to oblong-ovate, the segments pinnatisect to pinnatilobed, linear-lanceolate to oblong-elliptical; upper cauline leaves similar but sessile. Capitula (5-)10-70(-100) in a dense, compound corymb; involucre 5-8 mm in diameter. Outer row of florets tubular, female, zygomorphic, 3-toothed, rarely shortly ligulate, or actinomorphic, 5-toothed, hermaphrodite; inner florets tubular, 5-toothed. Achenes 1 -2-1 - 8 mm, 5-ribbed, with scattered epicarpic, sessile, transparent, non-mucilaginous glands; pappus 0-2-0-4 mm. 2л = 18. Roadsides, river-gravels and waste places; extensively cultivated for ornament and as a pot-herb, and in some regions naturalized. Almost throughout Europe. All except Az BI Cr Sb; not native in Hb.

Plants with finely dissected leaves occur in Corse, Sardegna and Sicilia and are sometimes recognized as separate species or varieties. Their status requires further study.

T. funkii Schultz Bip. ex Willk. in Willk. & Lange, Prodr. FI. Hisp. 2: 102 (1865), described from a single collection from S. Spain (Sierra Nevada), needs further study. It is described as a much-branched, pubescent, caespitose annual with very small solitary capitula at the ends of branches.
