The attractive, rich, golden-yellow flowers of this Daisy-like perennial appear in May and June in moist meadows and thickets, and in swamps. It is strikingly clean cut and beautiful. The slender, usually smooth, upright stalk is hollow and sparingly leafy. It is angular and twisting in growth, and rises from one to two and a half feet in height, solitary or tufted, from a strong-scented root. The lower leaves are long stemmed, and are long, rounding, heart-shaped, with scallop-toothed edges. Those on the stalk are partly clasping, and are lance-shaped and deeply cut and notched. The foliage is smooth and thin, and together with the stalk is often stained with purple. The flower heads have many tiny, deep yellow, star-shaped florets, that are closely tufted with a flaring fringe of from eight to twelve short, recurved deep yellow ray flowers, loosely set around and just below them. The ray flowers are finely grooved, and their tips are slightly notched. They are all set in a deep, smooth yellow-green cup, and several heads, perhaps a dozen, are comfortably gathered in a somewhat flat-topped terminal cluster. The roots are used in medicine. Senico is derived from the Latin, Senex, an old man, and refers to the silky white hairs that succeed the flower. This Ragwort is found from Canada to Florida, and Texas.
