Safety Overview
1.Erigeron Speciosus — Introduction & Highlights
Erigeron speciosus, commonly known as Aspen Fleabane, Showy Fleabane, or Oregon Wild-Daisy, is a resilient perennial herbaceous plant belonging to the Asteraceae family, specifically the Astereae tribe. Native to a vast expanse of western North America, its distribution ranges from British Columbia and Alberta in Canada down through the western United States (excluding California) and into a disjunct population in Baja California, Mexico. This robust plant typically forms a bushy habit, reaching heights of 1 to 2 feet, adorned with broad, ovate leaves that often feature serrated edges and a vibrant green hue.
Its erect stems branch out, culminating in clusters of showy, daisy-like blossoms, characteristic of the fleabane genus. Aspen Fleabane thrives in diverse habitats, from dry to wet meadows, big sagebrush communities, and quaking aspen woodlands to openings within coniferous forests, often found at elevations between 2,000 and 11,220 feet (600-3,420 meters). It exhibits remarkable cold tolerance during the growing season and prefers full sun exposure.
The plant adapts well to a variety of well-drained soils, including sandy, gravelly, and clay-loam types, with a preference for calcareous or non-calcareous soils with a pH between 6.6 and 7.2. Its ability to tolerate varying soil conditions and cold temperatures underscores its hardiness and widespread presence in mountainous and intermountain regions.
