Why Plant Swamp Milkweed?

The monarchs applaud your choice! You may choose Swamp Milkweed for its intricate, rosy pink flowers that give off the delicious scent of vanilla, but monarch butterflies view this Spirit as a life-giving host plant. Milkweed leaves are the only thing that monarch caterpillars eat. Fritillaries, swallowtails, and many other gorgeous butterflies may also visit its blossoms to sip its sweet nectar. Hummingbirds may zoom in for a drink, too. Plant Swamp Milkweed within view of your deck or patio, so you can enjoy watching the aeronautics of all the winged creatures that come to visit this special plant.

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 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.

How To Plant 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!

How To Prune

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 Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our big trees, sizes XL and bigger, require expert delivery and care, that means our extra-large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care. We deliver your trees and plants directly to you. Ask Bower & Branch about planting services – we'd be happy to assist in installation.

*For Big trees and Shrubs, Size XL and bigger: Review our Seasonal Shipping Timelines and Policy here.

Your trees and plants are grown across the United States at various Bower & Branch Growers. Depending on your location, your plant orders may be shipped from various locations. Please expect orders with multiple items to be delivered over a number of days as a result. Orders made up of numerous items or selections will not arrive at your home on the same day.

Shipping Delays:

From time to time, Bower & Branch Growers may determine to delay order shipment based on various factors for plant health. Weather in your region, as well as, where your plants are grown, is always considered when shipping. Extreme weather conditions may delay some or all of your order. Bower & Branch allows our Growers to make final shipping decisions based solely to benefit your trees and plants’ health and success.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
