Milkweed Swamp

Swamp Milkweed is a tall, showy perennial native to Ontario. In summer, clusters of fragrant pink to mauve flowers appear and attract bees, butterflies, and other pollinators. It is also an important larval host plant for Monarch butterflies and is one of the more commonly used milkweeds for egg-laying.

Swamp Milkweed grows best in full sun with moist to wet soil and is especially well suited to rain gardens, pond edges, and other damp locations. Despite its common name, it also grows well in average garden conditions as long as the soil does not become excessively dry. It has a more clump-forming, controlled habit than Common Milkweed, making it well suited to regular garden beds.
