Hulsea heterochroma, commonly known as redray alpinegold, is a species of flowering plant in the family Asteraceae.
It is native to the Southwestern United States and California. It grows in chaparral, yellow pine forests, and open habitats between 3000feet-9000feetft (-ft) in elevation.[1]
Hulsea heterochroma is an annual or perennial herb growing thick, leafy green stems to heights sometimes over one meter (40 inches). The toothed leaves are 10 to 20 centimeters (4-8 inches) long. Leaves and stem are covered in glandular hairs.[2]
The leafy inflorescence produces many flower heads also completely covered in small glandular hairs. The green, lance-shaped phyllaries are over a centimeter (0.4 inch) long. The center of the flower head is filled with many yellow disc florets, while the edge is fringed with 28–75 narrow, thready red-orange to reddish pink ray florets each up to a centimeter (0.4 inches) long.
The fruit is a hairy achene 6 to 8 millimeters (0.24-0.32 inches) long.
