The orange-coloured flowers and grimy stem will always keep this attractive Hawkweed from becoming confused with any of the yellow-flowered species. It has become naturalized here, and came from Europe. The generic name is derived from the Greek, hierax, a hawk, because the ancients thought that these birds sharpened their eyesight by feeding on these plants. The slender, round, grooved stalk rises from six to twenty inches from a rosette of leaves. It is quite naked, excepting for one or two small stemless leaves, which it bears near the ground. Its green colour is obscured by numerous, dull brownish hairs with which it is begrimed. The long oval, tufted leaves are narrowed at the base, and are toothless. They are covered with long, whitish hairs. The flower head is composed of numerous short, yellow-centred, orange-red, five-toothed, overlapping, strap-shaped florets that curve outward from the centre. The green cup is covered with the dark hairs. Several heads are rather closely grouped on short stems in a terminal cluster at the top of the stalk. Grim the Collier is a popular English name for this Hawkweed and applies to the general grimy or sooty appearance of the stalk. It is found in fields, woods, and along roadsides, from June to August, from eastern Canada to Pennsylvania.
