Erigeron tener is a North American species of flowering plant in the family Asteraceae known by the common name slender fleabane. [2] It is native to the western United States, largely in the Great Basin, in the states of California, Arizona, Nevada, Utah, Oregon, Wyoming, Idaho, and Montana. [3] [2]
Erigeron tener grows in open, rocky habitats. It is a perennial herb up to 20 centimeters (8 inches) tall, producing a large taproot and a woody caudex. It is surrounded at the base by narrow oval leaves up to 8 cm (3.2 inches) long, on petioles. There may be a few much smaller leaves along the stem. The inflorescence is made up of 1-3 flower heads per stem, each head lined with hairy, glandular phyllaries. The head contains 15–40 blue or purple ray florets surrounding numerous yellow disc florets. [4] [5]
