Alice eastwood's fleabane is a California native perennial found in the northwestern bioregion in meadows and woodland openings at elevations of 1,300 to 2,200 meters. Flowering from June to September, this plant produces white to lavender-tinged flowers with ray flowers 10 to 15 millimeters long that often dry to a subtle lavender or bluish color. Growing 30 to 100 centimeters tall with few-branched stems emerging from a short, thick fibrous-rooted rhizome, the plant has a delicate spreading growth habit. Its basal leaves are oblanceolate with coarse teeth, covered in spreading hairs, while mid-stem leaves are lance-shaped and partially clasping the stem. The flower heads, arranged on long stalks, feature 45 to 80 ray flowers in clusters of 1 to 7, creating a distinctive and airy appearance.
