Erigeron lassenianus is endemic to the high mountains of northern California, from close to the Oregon border south as far as northeastern Mendocino County and El Dorado County.[2][3]
Erigeron lassenianus is a member of the coniferous forest understory. It grows erect or in low patches on the ground, reaching a maximum height of about 35 centimeters (14 inches). Its blue-green hairy foliage grows in a basal patch and along the stem, the leaves long and straight to spoon-shaped and between 5 and 15 centimeters (2-6 inches) in length. Atop the few-branched stem is an inflorescence of one to several flower heads each 5 to 12 centimeters (2-5 inches) wide. The center of each head is packed with golden yellow to pinkish-orange disc florets. Some heads also have ray florets which may be lavender or pinkish.[4]
