Identification – Blacktip Ragwort
Small blacktip ragwort grows 5-60 cm (2-24 inches) tall with long basal leaves and yellow flowers. The flower is ray or daisy-like with a variable number of petals. Stems can be single or in a small cluster and often has a branched inflorescence with the flower cluster often being the same height. The phyllary or bract is black-tipped for which the flower is named. Leaves are petiolate, rounded or elliptic, and slightly toothed. Any leaves higher on the stem are much smaller than the basal leaves. Blacktip ragwort has a thick rhizome and coarse, spreading root with many branches.
