Estimated Native Range
Summary
Collinsonia canadensis, commonly known as Richweed or Stone-root, is a deciduous perennial herb native to rich, moist deciduous forests and stream banks in the Eastern United States. It typically grows up to 4 feet (1.2 m) tall and features large, ovate, sharply toothed leaves that are green in color. From mid to late summer, it produces terminal clusters of small, tubular, lemon-scented yellow flowers that are particularly showy due to their contrast with the dark forest understory during a season when few other plants are in bloom.
Richweed is valued for its aromatic flowers and its ability to thrive in shaded conditions, making it a suitable choice for woodland gardens, shaded borders, and naturalized areas. It prefers part shade but can tolerate full shade, requiring medium amounts of water and well-drained soil with rich organic matter. While not commonly used in cultivation, it has potential as a ground cover due to its foliage and fragrance. Gardeners should note that it can be slow to establish and may require patience. It is generally free from serious pests and diseases, but powdery mildew can occasionally be a problem in humid conditions.CC BY-SA 4.0
