Seedling
Quite similar to that of Scolymus hispanicus. Cotyledons elliptic large, 16-22 x 8-10 mm, short-stalked, with rounded apex, glabrous. Primordial leaves rosette-shaped, simple, lanceolate to elliptic, toothed with broad soft indentations and long spines. Leaves and petioles hairy. The hypoctyled axis is short and thick. Plantlet of a shiny green.
Adult plant
Scolymus grandiflorus is a thorny perennial, which can reach 50 cm in height. Stem erect, simple or little branched, strongly winged, with continuous spiny wings, pubescent. Leaves simple, sessile, deeply pennatifid, the linear cauline ones, little embracing but decurrent, the base extending in spiny foliaceous wing along the stem. The upper leaves forming an involucre at the base of the capitula, with pubescent underside. Capitula sessile in leaf axils or along terminal axis, or pedunculate terminals, large (10)12-20(21) mm in diameter (twice the diameter of capitula of S. hispanicus). Involucre formed of 1-3 involucral outer leaves oval, lanceolate with acute, mucronate spiny apex and margin with long coarse spiny teeth and linear oblong inner bracts mucronate, in 2-3 rows. Florets all yellow ligulate with ligule up to 3 cm long, short bi-tridentate at apex. Achenes 3.5-5 mm, strongly compressed dorsally, intimately enclosed in the scales of the receptacle, surmounted by a pappus of 2-5 stiff, smooth setae.

Scolymus grandiflorus can be confused with S. hispanicus and S. maculatus.
S. maculatus can be distinguished by the presence of 5 involucral leaves around the flower head and achenes without pappus, a whitish stem with continuous spiny wings
S. hispanicus is distinguished by 1-3 involucral leaves around the flower head, a flower head of 6-10 mm diameter and a pappus of scabrous bristles at the top of the achenes, a whitish green stem with interrupted wings
S. grandiflorus is distinguished by 1-3 involucral leaves around the flower head, a flower head 12-20 mm in diameter, a pappus of hairless bristles at the apex of the achene and a green uninterrupted winged stem.
