Product Description

"As the name suggests Swamp Milkweed can take wet conditions, but it can handle moderate water as well. There are multiple cultivars due to the plant being bred by the cut flower industry. To my delight I saw it being sold in Munich, Germany as a cut flower in all the train stations. It has a broad native range in the U.S. from Colorado to the East Coast. Swamp milkweed has no underground runners and will not spread to other areas of the garden." — Bobby Gendron

Growing Instructions: Start Swamp Milkweed seeds outdoors in late November. Pick a location with full sun and prepare soil for good drainage, if needed. Plant seeds 1/8" deep and 18” apart, using 3 seeds per hole. Water once, and then allow the winter rain and/or snow to provide moisture until the spring. The seeds will germinate 10 - 20 days after the danger of nighttime freezing has past. Once the seedlings reach 1", thin out so you have individual plants spaced 18” apart. Water regularly allowing the soil to go nearly dry between each watering. Fertilize monthly in the summer with a general purpose fertilizer. If you prefer to plant the seeds outdoors in the spring, read our detailed instructions on cold moist stratification.
