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]
