Swamp loosestrife (Decodon verticillatus) is the perfect native plant to naturalize wet areas! This fast-growing, perennial sub-shrub will swiftly colonize open areas along banks of water. Growing 6-8 feet tall, swamp loosestrife has long, arching stems that gracefully bend over the ground or water. Each stem has whorls of crinkled, hot pink or rosy purple flowers with long stamens. In fall, the willow-like leaves of swamp loosestrife turn brilliant shades of orange, bronze, and red.
This wetland plant is both deer resistant and low maintenance. Swamp loosestrife is an excellent plant for filling in space along water features. Grow this wildflower next to ponds, streams, and in marshy areas. In mid-to-late summer, the flowers of swamp loosestrife offer nectar to bees and butterflies while the plant itself serves as a host plant for various native moths.
Swamp Loosestrife Care
Swamp loosestrife can be grown in full sun, partial shade, or full shade. This plant needs to be grown in wet soils; it cannot tolerate soils that dry out frequently. As an emergent plant, swamp loosestrife can be grown in shallow standing water (generally less than 12” of water). Plant this shrubby perennial in boggy soils with an acidic to neutral pH. Swamp loosestrife does not need fertilization.
If desired, prune back the flowering stems to the shrubby base of the plant in winter. Since swamp loosestrife can spread prolifically, care should be taken to ensure that it does not overtake surrounding plants. Swamp loosestrife can clonally propagate itself when the tips of its stems touch the ground or water. Trim back the stem tips to control the spread of this plant.
Swamp Loosestrife Spacing
Swamp loosestrife will quickly fill in space wherever it is planted. Plant swamp loosestrife about 6-8 feet apart to allow room for it to spread.

We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
