Hieracium venosum (Robin’s plantain, rattlesnakeweed, or rattlesnake hawkweed) is a species of hawkweeds in the dandelion tribe within the sunflower family. It is widespread and common in south-central Canada (Ontario) and the eastern United States (from Michigan east to Maine and south as far as Florida and Mississippi).[3][4][5]

Hieracium venosum is a hairy herb up to 45 cm (18 inches) tall, with most of the leaves crowded around the base of the stem. One plant can produce as many as 20 flower heads, each with 30–45 yellow ray flowers but no disc flowers.[6]
