About Winged Loosestrife: Though often confused with its more invasive cousin, this well-mannered wildflower is actually protected and hard to find in the wild. The genus name Lythrum means “blood,” referring to a folk belief that some species in this family could stanch bleeding wounds. The species name “alarum” means “winged,” since the stems of this plant have thin ridges or wings.
Winged Loosestrife Germination: Direct sow seeds in late fall; since they need light to germinate, plant them on the surface of the soil. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting. Keep the soil lightly moist until germination. This seed can also be started indoors 6-8 weeks before planting in the spring.
Growing Winged Loosestrife Seeds: Seedlings are extremely vulnerable to heat and drought, and also have trouble competing with weeds. Water them regularly, since this plant loves moist soil and even tolerates standing water. These blossoms attract hummingbirds, bees, and butterflies. Deer tend to avoid this plant.
Harvesting Winged Loosestrife: These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.
Saving Winged Loosestrife Seeds: After the flowers fade, a slender pod will develop. Since the tiny seeds easily blows away, shake the seed out of the pods as soon as they open. Store the seed in a cool, dry place.
