Suitable for woodland edges, partially shaded gardens, and naturalized areas. Native to eastern North America.
Plant Details
Bloom Colour: Yellow
Bloom Time: Mid to Late-Summer
Sun Requirements: Part-Sun to Shade
Moisture: Dry to Moist-Drained
Phenology: Stems emerge May. Leaves fully developed by June. Yellow flowers appear July-August. Seeds mature September-October. Dead stems persist through winter.
Wildlife Value: Seeds heavily used by songbirds; nectar source for bees and butterflies; provides cover for wildlife; leaves eaten by deer
Habit Over Time: Forms extensive colonies through vigorous underground rhizomes, creating loose stands of upright stems that emerge singly or in small clusters rather than dense clumps. While it can spread assertively in favorable conditions, its open growth pattern allows other strong-growing plants to coexist between the stems. The rhizomatous spread can be quite rapid, so it's best used where it can be contained by barriers or equally vigorous neighbors.
Height: Medium to Tall (2-5 feet)
