Showy Monarch Butterfly Host Plant, turn your plain landscape into a gorgeous habitat for butterflies! The Swamp Milkweed (Asclepias incarnata) is a native perennial that makes it easy! Milkweed's fragrant, bright pink, and white pom-pom blooms are composed of many dozens of small flowers.

You'll love the wildflower clusters in summer! Look closely to study each five-petaled true flower with its range of colors from pink to mauve into white. Smell their sweet and spicy honey-scented fragrance, too. They'll perfume your yard and boost your mood like "living aromatherapy"!

This native choice supports beneficial pollinators and butterflies with nutrient-rich nectar for several months as midsummer heats up. The garden will dance with these visitors, and every minute brings a rewarding experience for mindful watchers. Swamp Milkweed are very important host plants for Monarch caterpillars. Watch for Monarch chrysalis hanging below the undersides of the long, lance-shaped leaves.

Swamp Milkweed does take its time leafing out in spring, but once it gets going the six-inch, lance-leaf foliage will fill out your plant nicely. This native Milkweed is hardy throughout USDA growing zones 3 to 6 and grows up to 4-5 feet tall and 2-3 feet wide. There are no significant insect or disease issues with the Swamp Milkweed either! The white milky sap inside the leaves and stems is bitter and avoided by deer and rabbits, but loved by beneficial insects!

Planting and Application:

Swamp Milkweed is an attractive, herbaceous perennial that would be perfect for those difficult, low spots in your yard, as it thrives in moist conditions. You can easily incorporate this helpful plant as a lively addition to your perennial borders. Use them in planned Rain Gardens to help filter potentially polluted water runoff from roofs and streets.

This moisture-loving selection develops into a uniquely valuable "must-have '' for your Butterfly Garden! If you love butterflies, it's a great way to attract them, and Monarchs are especially fond of Milkweed. It is often planted specifically to encourage Monarchs in a region. Plant several in drifts through the center of your plantings.

Prepare to be thrilled and amazed at the amount of "flying flowers'' that you'll see working these tiny flowers over each day. Butterflies, moths, and beneficial pollinators cherish these nectar resources! Give kids and garden visitors a delightful tour through our natural world. Nature Hills is so pleased to offer this special clump-forming perennial...along with many other native wildflowers.

Milkweed contains natural compounds like cardenolides, which protect the baby caterpillars from being eaten by birds. You'll love seeing the cute black, white, and yellow caterpillars munching away on your plants!

If you grow your own food as part of an Edible Landscape, you'll definitely want to grow Swamp Milkweed near your Victory Garden to encourage pollinators to come explore your vegetables and orchards.

After the flowers have faded, Swamp Milkweed forms eye-catching four-inch pods that are a favorite of young and old alike. Once ripe, they'll split to release the brown seeds...using silky white plumes to catch the wind and reach new destinations.

These pretty blooming perennials shouldn't be considered weeds. Sticks and stones! Sure, they perform really well and can spread here and there in your yard, but you can control their self-seeding and spread by cutting off the pods before they split open. Dry them for gorgeous seasonal arrangements that last all winter long as an effective, charming method of size control! 

Others encourage their growth and spend happy moments blowing their seeds to new parts of the yard. Your friends may beg you for some of the pods, too!

Wildcrafters and homesteaders can research an amazing variety of uses. In its various stages, Milkweed pods are used as a nematode insecticide, as an adhesive, and even as a poison ivy treatment.

#ProPlantTips for Care:

As its name implies, erect-branching perennial Swamp Milkweeds love moist, swampy conditions! They'll also adapt to well-drained areas with consistent moisture. You'll get the best performance with a planting site in full sun because Swamp Milkweed needs at least six hours of sunlight a day.

Ideally, they love a place that stays a bit damp. Why not decorate the area around your drain spout or create a Rain Garden with their help? This water lover needs a consistent schedule of water all season. Add a three-inch layer of mulch to cover the root system and reduce surface evaporation.

Please leave the stalks standing overwinter, as they provide valuable shelter, then cut down the stalks to an inch high in early spring.
