Pink swamp milkweed Leaves are long (up to 6 inches). Seeds are flat and brown with silky white hairs attached which come from pods, and split open when ripe. Seeds are dispersed when their silky hairs catch the wind.
Swamp milkweed occurs naturally in floodplain swamps, hydric hammocks, wet pine flatwoods and marshes. It typically blooms in summer and attracts many pollinators. It is a larval host plant for monarch, queen and soldier butterfly caterpillars. In my garden it grows in partial shade and sunny locations - both in pots and in the ground. Once established, it does well in regular Florida conditions. It goes dormant around late October-November. It may appear above ground not to be viable at this point. If the roots are still viable, the plant will come back from the roots. Sometimes it will even skip a year and come up the 3rd year and every year after that. Part of the native plant cycle.
