The flowerheads are seated at the end of the stem or in the limbs of the higher leaves, and are arranged in a spike, which are subtended by two or three leaflike bracts.
Each flowerhead is circled by an involucre that consists of many spine-tipped bracts of usually between 9 and 15 mm long, in several rows, the outer papery and shorter than the inner ones, which are leaflike in consistency and have a white papery margin.
These surround the common floral base (or receptacle), which is mostly 13–18 mm in diameter conical in shape and is set with ovate papery bracts called chaff or paleae.
Inplanted are dorsally compressed cypselas, each enclosed by a palea, the outer rows higher than the inner ones.
There are three to seven pappus bristles on top of the cypselas in the centre, three to five with bordering the involucre.
The yellow to yolk-yellow, strap-like corolla is usually 25–37 mm long, ends in five teeth, and does not carry black hair.
Flowers are present from May to July.
