Erigeron pumilus (shaggy fleabane, vernal daisy) is a hairy North American species of perennial plants in the (daisy family). It is widespread across much of western Canada and the western United States, from British Columbia east to Saskatchewan and south as far as Oklahoma and the San Bernardino Mountains of California. There have been reports of the plant growing in Yukon Territory, but these were based on misidentified specimens. "Pumilus" means "dwarf", referring to the small size of this hairy little plant.
