Maintenance

Versatile plant that will grow in fields, wet meadows, ditches, roadsides, pond edges, streams. Because Winged Loosestrife is naturally found in wet meadows, it is a good plant for the lower slopes of rain gardens or the dry fringe. Winged Loosestrife (Lythrum alatum) grows in a dense ball almost like a short shrub. Plant it with other late summer blooming natives. Not to be confused with the invasive Purple Loosestrife (Lythrum salicaria) Propagation: Seed.

Comments

Petals have a darker purple mid-vein and resemble the texture of wrinkled tissue paper. Winged Loosestrife is beneficial to hummingbirds, long-tongued bees, green metallic bees, bee flies, butterflies, and skippers.
