Summary

Hieracium albiflorum, commonly known as White Hawkweed, is a perennial herb native to a variety of habitats in western North America, including open woodlands, forest edges, meadows, and alpine zones, ranging from Alaska to Mexico and east to Manitoba and South Dakota. It typically grows at low to moderate elevations. This species reaches a modest height of 1-2 feet (30-60 cm) and spreads to a similar width. White Hawkweed is characterized by its clumping form and multiple flower heads, each with 6-25 white ray flowers resembling a dandelion but more prolific in bloom. The flowering season extends through summer, and the flowers are quite showy, attracting various pollinators.

White Hawkweed is appreciated for its adaptability to different environments and its role in supporting pollinators. It is often used in wildflower gardens, meadow plantings, and for naturalizing areas. In cultivation, it prefers well-drained soils but can tolerate a range of soil types, from dry to moderately moist. It thrives in full sun to part shade. While generally low-maintenance, it can become invasive in some conditions, spreading by both seed and rhizomes. Gardeners should be aware of its potential to spread and manage it accordingly.CC BY-SA 4.0
