Description
Erigeron aequifolius is a small perennial herb growing a hairy, glandular stem up to about 20 centimeters (8 inches) tall from a woody caudex and taproot. The small leaves are equal in size and evenly spaced along the stem. The inflorescence is a usually solitary flower head at the tip of the stem. The head contains many yellow disc florets surrounded by a fringe of ray florets which are white when new and turn blue as they dry. The fruit is a tiny achene with a pappus of bristles.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250066544 Flora of North America, Erigeron aequifolius H. M. Hall, Univ. Calif. Publ.
