Poke Milkweed
Herbaceous perennial reaching 1-1.5 m tall. Features large, opposite leaves and loose clusters of white to pale pink flowers blooming in early to midsummer. Prefers moist, well-drained soils and partial shade to full sun. Less aggressive than other milkweed species. Important larval host for monarch butterflies. Suitable for woodland edges, meadows, and naturalized areas. Produces pods with silky-tufted seeds. All parts contain cardiac glycosides toxic if ingested.
Plant Details
Bloom Colour: White to Pale Green
Bloom Time: Early to Mid-Summer
Sun Requirements: Part-Sun to Shade
Moisture: Moist-Drained
Phenology: Stems emerge late May. Leaves fully developed by mid-June. Blooms July-August. Pods develop August, releasing silky-tufted seeds September-October. Dead stems often persist through winter.
Wildlife Value: Host plant for Monarch butterflies; nectar source for butterflies and native bees; seeds eaten by small birds; deer resistant
Habit Over Time: Creates loose, upright clumps that maintain clear boundaries. While it may self-seed, it does not spread aggressively through rhizomes. The tall stems provide good structure while allowing views through to background plants. Works well as an accent plant.
Height: Tall (3-5 feet)
