Summary
Anemonastrum richardsonii, commonly known as Yellow Thimbleweed, is a perennial herb that is native to moist alpine meadows and subarctic regions across North America, particularly in the Northern United States, Canada, and Alaska. It typically grows to a height of 12 to 24 inches (30-60 cm) with a similar spread. This plant is characterized by its deeply lobed leaves and small, nodding, cup-shaped yellow flowers that bloom in mid to early June. The flowers are perfect, containing both male stamens and a central female pistil, and are followed by distinctive, thimble-like seed heads that persist into late summer.
Yellow Thimbleweed is valued for its early summer blooms and its ability to thrive in cooler climates. It is often used in wildflower gardens, borders, and naturalized areas where its cheerful yellow flowers can brighten up the landscape. While it prefers part shade, it can tolerate a range of light conditions from full sun to full shade, provided it has access to consistently moist soil. It is important to note that this plant requires soils with good moisture retention and does not tolerate drought well. Despite its preference for wetter conditions, it is relatively low maintenance once established.CC BY-SA 4.0
