cinderella asclepias incarnata butterfly weed seeds

Asclepias incarnata 'Cinderella' (Swamp Milkweed) is an erect, clump-forming perennial prized for its brilliant clusters of vanilla scented, rose-pink flowers, which bloom continuously for weeks from midsummer to early fall. The flowers are a great source of nectar for butterflies, hummingbirds, bees, and other beneficial insects. Sitting atop upright branching stems, clad with stiff, lance-shaped, taper-pointed leaves, the colorful umbels give way to attractive seed pods in the fall, which persist into winter. When the seed pods open, they reveal seeds with long, silvery-white, silky hairs that look great in dried flower arrangements. A great choice for the flower garden and for natural settings.

Milkweed plants are critical to the monarch butterflies survival, whose population in North America has plummeted by 90% in the last 20 years. By planting milkweed in your own garden, you can help reverse the fortune of these beautiful insects!

The Facts:

“As the name suggests Swamp Milkweed can take wet conditions, but it can handle just moderate water. There are multiple cultivars due to the plant being bred by the cut flower industry. This cultivar, Cinderella Swamp Milkweed is a fuchsia and pink version that is stunning. To my delight I saw Swamp Milkweed being sold in Munich, Germany as a cut flower in 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 Cinderella Swamp Milkweed seeds outdoors in the spring after the danger of nighttime freezing has past. 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. Keep the soil evenly moist until the seeds germinate in 10 – 20 days. 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. To get a head start, seeds can be planted indoors in the late winter. Transplant outdoors after the danger of nighttime freezing has past.
