    Why plant Audubon® Native Swamp Milkweed?

    You probably know about the link between milkweed and monarch butterflies, but did you know milkweed is good for birds, too? Swamp Milkweed is one garden-worthy species that serves our feathered friends in important ways. This stately native Spirit attracts many insects—not just monarchs—that in turn attract insectivorous birds. Swamp Milkweed in particular draws aphids, which is not at all a bad thing if you’re a warbler, finch, sparrow, or chickadee! In addition, hummingbirds may sip from the flowers, and all sorts of birds use the downy-soft “silk” to line their nests. A boon to wildlife on six legs AND on two!

    Milkweed was a hero in World War II. When Japan occupied the Indonesian island of Java, the Allies lost their access to tropical Kapok Trees, which provided the buoyant stuffing for life preservers. Resourceful engineers looked to the Common Milkweed and the Swamp Milkweed instead, which produce little silky floss parachutes to carry their seeds through the air. The floss served as an excellent substitute for Kapok fibers, and American schoolchildren were recruited to gather Milkweed pods for the war effort. It is estimated that 11 million pounds of Milkweed were gathered for the troops!

    How to use Audubon® Native Swamp Milkweed in the landscape?

    As you may have guessed by the name, Swamp Milkweed enjoys a site where it can receive plenty of moisture. It’s perfect for a rain garden or for that low spot in your yard that always seems to stay soggy. However, it does just fine in regular garden conditions, too.

    What is the definition of Native?

    “In the United States, a native plant is defined as one that was naturally found in a particular area before European colonization. Native plants are the foundation of a region’s biodiversity, providing essential food sources and shelter for birds, especially those threatened by the changing climate. Since native plants are adapted to local precipitation and soil conditions, they generally require less upkeep, therefore helping the environment and saving you time, water, and money.” – The National Audubon Society

    How To Plant Audubon® Native Swamp Milkweed

    Grow Swamp Milkweed in full sun for best results and irrigate regularly. Do not let it dry out. Plants will be tall and lush in wet soil, a bit shorter and more compact in average conditions. One problem that may affect Swamp Milkweed is aphids feeding on the new growth. Simply knock them off with a jet of water from the hose. Do not use pesticides on or near this monarch butterfly host plant! Cut plants back in late fall or any time before new growth appears in the spring. Swamp Milkweed is late to emerge, and it’s a good idea to mark its location before it goes dormant for the winter, so you remember where it is.

    How To Water

    Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water slowly and thoroughly. Watering needs may be altered due to extreme weather conditions. Remember, Swamp Milkweed likes lots of water.

    How To Fertilize

    Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late year. Continue this for three years to get your plant well established.

    How To Prune

    Each fall, just before winter sets in clean up the previous years foliage and compost it. Be sure your perennials are mulched well for winter protection. Two inches of an organic mulch will do the job. Consider leaving the plant debris in place through the winter and doing your clean up on the weather warms in the spring. While it doesn't make things neat and tidy, the debris provides overwintering protection for insects, their eggs and pupae including our native Viceroy butterfly.
