A pollinator magnet!  Clump-forming perennial with branched stems bearing narrow, willow-like leaves.  Plants are topped with tight clusters of fragrant pink to mauve flowers that bloom June to July.  Flowers are followed by seed pods that split open when ripe releasing silky-haired seeds that are wind-dispersed.  Plants have deep tap-roots and are best left undisturbed once established.  Research indicates that, in gardens, Swamp Milkweed is best planted along perimeter and separate from other plants to increase visibility and accessibility to pollinators.  Tolerates clay soil.  Attracts butterflies, hummingbirds, native bees and beneficial insects that prey on pest insects.  Larval host to Monarch and Queen butterflies and Milkweed Tussock moths.

Planting tip: Swamp Milkweed is a heat-loving plant. Plants are slow to emerge in the spring and will bloom only sporadically in their first year. When planting, be sure NIGHT-time temperatures remain above 50 degrees F. Otherwise, plants may go into a second dormancy. Plant high so that the crown is above the soil line. Swamp Milkweed resents being transplanted and will drop leaves if stressed.
