Nipplewort is one numerous yellow, dandelion-like flowers, but its tall wiry stature - plants are commonly a metre tall and sometimes rather more - is a distinguishing feature as also are the small flowers and the nipple-like buds. The flower heads are arranged in loose panicle, each compound ‘flower’ comprises typicaly 8 to 15 pale-yellow rayed florets, which are often, although incorrectly, referred to as petals. Unlike other dandelion lookalikes, a Nipplewort flower head does not develop into a white pappus of parachute-like seeds. The fruits of this plant are yellowish- brown achenes typically 4mm long.
