Herb, annual or biennial, 10-150 cm high, with taproot. Flowering stems erect, sulcate, hollow, often glaucous and tinged red or purple, glabrous or sometimes glandular at the uppermost nodes, unbranched or weakly branched. Lower cauline leaves oblong or narrowly obovate, 6.0-30.0 cm long, 2.0-12.0 cm wide, usually pinnatisect, pinnatipartite or entire, spinose or entire, petiole-like attenuate with a winged petiole; terminal lobe deltoid or nearly circular; lateral lobes 4-6, oblong, obtuse or acute. Middle and upper cauline leaves amplexicaul and auriculate with acute or obtuse, entire or denticulate auricles, glabrous, glaucous on both surfaces. Synflorescence paniculiform or corymbiform, with 5-15 heads. Peduncle 0.5-2.5 cm long, glandular, floccose or glabrous. Heads with more than 100 flowers. Involucre at flowering campanulate, 8.0-12.0 mm long, at flowering 6.0-10.0 mm in diameter; involucral bracts glandular or glabrous, margin scarious; outer involucral bracts narrowly deltoid, 3.0-5.0 mm long, 1.5-2.0 mm wide; inner involucral bracts linear-ovate, up to 12.0 mm long, 2.0 mm wide. Corolla ligulate, yellow or less often white; tube c. 7.0 mm long, thinly woolly towards apex; ligule c. 6.0 mm long, 1.0 mm wide. Anthertube c. 2.5 mm long; apical appendages obtuse. Style c. 12.0 mm long; branches c. 1.2 mm long. Achenes narrowly obovoid in outline, strongly compressed, c. 3.0 mm long, 1.0 mm wide, scabridulous, wrinkled transversely, pale brown, with 3 longitudinal ribs on each face. Pappus white, up to 7.0 mm long, flexible, remotely scabridulous or barbellate.

Sonchus oleraceus is considered to have evolved through natural crossing of S. tenerrimus (x = 7, 2n = 14) and S. asper (n=9, 2n=18).A,B

Chromosome numbers

The chomosome number of 2n = 32 has been explained as allotetraploid, resulting from hybridisation between x = 7 (S. tenerrimus) and x = 9 (S. asper) progenitors.
