Swamp Milkweed is a lovely, large perennial that gets stunning bunches of pink/purple flowers almost all summer long. This plant loves wet soils, normally found along streams, in wetlands, and wet meadows. While it loves wet soil, it is worth noting it can handle drought once established, and will tolerate clay soils and is very deer resistant. The single most important thing about this plant is its wildlife value. It is an absolutely crucial plant for Monarch and Queen butterflies, and is invaluable to native bees, hummingbirds, and all butterflies as a nectar source. If you want butterflies galore, this is the plant for you! In fall, It gets a very interesting seed pod, offering interesting winter interest. The pods are commonly used in dried flower decorating. These plants look especially lovely as a grouped/naturalized planting.

Shipping Information

At Direct Native Plants, we take many precautions to make sure your plants will arrive in the best condition possible.

Our perennials are grown in a 4” quart-sized pot. These plants are then cut back to fit our packaging, placed in a protective clamshell container (made from recycled materials), and then shipped to you in a cardboard box. PLEASE NOTE: Perennials can be shipped in bundles up to 6. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Trees and shrubs are grown in a 7” tall container (referred to as a 1-gallon pot), and depending on the species will be between 12” and 36”. We bag the root section of these plants to prevent them from drying out in transit and ship them in a tall cardboard box. PLEASE NOTE: Trees and shrubs can be shipped in bundles up to 4. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Direct Native Plants now ships via FedEx. Orders ship out Monday through Wednesday of each week, and depending on how close you are to our nursery in Maryland, shipping will take anywhere from 1-4 business days.
