Yellow Loosestrife

Lysimachia punctata

Yellow loosestrife (Lysimachia punctata) plants form a bushy, fast-spreading clump of green leaves, with loose spikes of bright-yellow starry flowers appearing in early to mid-summer. The flowers rise above whorls of light green serrated leaves. Yellow loosestrife is native to central Europe and Turkey, and this perennial has vigorous rhizomes that reach 36” in height and 12-18” across. It also self-seeds to form large colonies. Contact may cause skin irritation or an allergic reaction.
