features
The hairy teasel is a biennial plant that reaches heights of 60 to 120 centimeters. It is upright and branched. Both stems and leaves are more or less hairy and prickly. The leaves are fused at the base. The lowest are long-stalked, ovate, usually with entire margins and sometimes have two smaller leaflets . The upper leaves are ovate-elliptical , short-stalked and often tripartite .
The white or yellowish-white colored flowers are arranged in a dense, spherical, cephalic inflorescence , which has a diameter of 2 to 2.5 centimeters and nods before opening. The bracts are bristly ciliate and long pointed. The bracts are a little longer than the flowers.
The flowering period extends from July to August.
The number of chromosomes is 2n = 18.
ecology
The hairy teasel is a hemicryptophyte . The pre-male flowers open one after the other in concentric zones; they are pollinated by insects (preferably bumblebees ).
