Helianthus niveus is a species of sunflower known by the common names showy sunflower and snowy sunflower. It is native to northern Mexico ( Sonora, Baja California, Baja California Sur) and the Southwestern United States (Southern California, Arizona, New Mexico, and West Texas). [3] [4]
Helianthus niveus is a taprooted annual or perennial sunflower growing to a maximum height over 1 m (40 in). The leaves are oval or lance-shaped, often with irregular lobes or teeth, and are covered in soft, white hairs. The flower heads are fringed with 13-21 bright yellow ray florets up to 2.5 cm (1 in) long surrounding a center of yellow to purple-red disc florets. [5] [3]
Habitat
H. niveus grows in sandy soils, most often in sand dunes. [6]
