About

Erigeron maguirei is a species of flowering plant in the family Asteraceae known by the common names Maguire daisy and Maguire's fleabane. It is endemic to Utah in the United States. It is a perennial herb growing up to 28 centimetres (11 inches) tall. It grows from a taproot and a branching caudex. The stems are densely hairy. The inflorescence holds one to five flower heads each with several hairy, glandular phyllaries. The head has up to 20 white, pink-tinged, or pink ray florets 0.6 to 0.8 centimeters long, and many yellow disc florets at the center.

This plant can be found in the San Rafael Swell and Capitol Reef National Park in Utah. It grows in cracks and crevices in the Navajo Sandstone in canyons, mesas, and washes. It springs up in cool, shady areas where enough organic material accumulates in cracks that it can take hold.
