The flower heads have a width of 15 to 30 mm; they contain ray and tubular flowers. The bracts are pale, green or light brown and have membranous edges. The zygomorphic ray-florets are white and linear-elongated in shape. The radially symmetrical tubular flowers are yellow. The flowering period extends mainly from June to August. The achenes are pentagonal and have a crown-like pappus .

The number of chromosomes is 2n = 18 or 36.

Location and distribution
