Fun Facts

Fringed Loosestrife is found in moist woodlands, wetlands, stream edges, and damp meadows. It produces tall stems with pairs of oval leaves and bright yellow, five-petaled flowers in early to mid-summer. Unlike the invasive purple loosestrife (Lythrum salicaria), this species is a beneficial native plant and is unrelated despite the similar common name. It prefers moist, rich soils and it works well in woodland edges and naturalized garden areas. It is best grown in consistently moist soil. It can tolerate some shade but flowers best with more sunlight.
