Swamp Milkweed Seeds

Swamp Milkweed – Flower Seeds

Description
Swamp Milkweed is a native perennial known for its fragrant clusters of soft pink to mauve flowers and its vital role in supporting monarch butterflies. Blooming in mid to late summer, it provides an important nectar source for pollinators and serves as a host plant for monarch caterpillars. Unlike common milkweed, Swamp Milkweed has a more refined, upright habit and thrives in moist soils. A beautiful and beneficial addition to pollinator gardens, meadows, and naturalized areas.

I'm getting a mixture of some pink plants and some white plants with this collection.
