Summary
Polymnia canadensis, commonly known as Whiteflower Leafcup, is a perennial herb that is native to rich woods, thickets, and forest clearings of Eastern North America. It typically grows to a height of 2-4 feet and a width of 2-3 feet. The plant is characterized by its variable leaf shape, with deeply lobed leaves at the lower part transitioning to simpler leaves higher up. The small, inconspicuous flowers bloom in late summer and are often overshadowed by the large, attractive foliage. The sap is clear, sticky, and has a pleasant fragrance.
Whiteflower Leafcup is valued for its foliage and is used in shaded garden areas, woodland gardens, and naturalized areas. It is a low-maintenance plant that adds texture and greenery to part-shade gardens. While it prefers medium moisture, it requires well-drained soils and can tolerate a range of soil types, from clay to loam. It is not commonly afflicted by serious diseases or pests, but can occasionally suffer from leaf spots. This plant is not known for aggressive roots or invasiveness. It is important to note that Whiteflower Leafcup can spread by self-seeding and may require control to prevent unwanted naturalization.CC BY-SA 4.0
