Hieracium venosum


Hieracium venosum is a species of hawkweeds in the dandelion tribe within the sunflower family. It is widespread and common in south-central Canada and the eastern United States. Its common name comes from the fact that environments it is found in are typically also a home to rattlesnakes.
Hieracium venosum is a hairy herb up to 45 cm 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. It is a perennial that blooms from May to September, and prefers shady conditions with dry, sandy soil.
