Heliopsis parvifolia is a North American species of flowering plant in the family Asteraceae, known by the common name Mountain oxeye.[1] It is native to northern Mexico from Baja California east to Tamaulipas and south as far as Aguascalientes, as well as the southwestern United States (southern Arizona, southern New Mexico, western Texas).[2][3][4]
Heliopsis parvifolia is a perennial herb up to 80 cm (31 in) tall, spreading by means of underground rhizomes. The plant generally produces 1-5 flower heads per stem. Each head contains 6-19 bright yellow ray florets surrounding 40 or more yellowish-brown disc florets. The fruit is an achene about 5 mm (0.20 in) long. [5]
