description
Vegetative characteristics
The mock cornflower grows as a perennial herbaceous plant that reaches heights of 40 to 60 centimeters. The stems are branched and spread-ascending. The leaves are narrowly lanceolate, the lower leaves are undivided, the central ones pinnate and coarsely hairy, the upper ones smaller and with entire margins.
Generative characteristics
The 5 to 15 cm inflorescence stalk is leafless in the upper area and hairy like a cobweb at the end. The cup-shaped inflorescence has a diameter of 5 to 7 centimeters. The egg-shaped flower head cover measures 7 to 20 × 10 to 15 millimeters and is egg-shaped. The standing in five to seven rows bracts are blackish on the fine serrated edge and at the top, the outer long have a 1 to 3 mm, projecting mandrel. The base of the flower head is covered with long hair. The flower heads only contain tubular flowers . The marginal, sterile tubular flowers have dark purple to purple, 23 to 25 millimeters long, fused petals that end in 10 to 15 millimeters long, widely spread corolla lobes. The inner, fertile tubular flowers have fused petals 13 to 14 millimeters long that end in corolla lobes 5 to 6 millimeters long.
The flowering period extends from July to August.
The light gray-brown, barrel-shaped achenes have a crown-shaped pappus made up of several rows of non-grown, 1 to 2.5 mm long, unevenly toothed scales, the outer ones being shorter and narrower than the inner ones.
The number of chromosomes is 2n = 34.
