About this plant
Lysimachia punctata, commonly known as yellow loosestrife, brightens the summer garden with clusters of golden-yellow, star-shaped flowers that bloom profusely from early to midsummer. The blooms grow in whorled tiers along upright stems, creating a vibrant column of color that contrasts beautifully with the plant's lance-shaped, dark green foliage. The cheerful yellow flowers add warmth to borders and make a great addition to wildflower or cottage-style gardens.
Native to parts of Europe, Lysimachia punctata thrives in damp meadows and along streambanks, adapting well to garden settings that mimic these conditions. Its vigorous growth and ability to spread make it an excellent choice for naturalized areas or for creating a dense ground cover in larger garden spaces. Its colorful display and hardy nature add a dynamic presence to garden designs, providing seasonal interest and supporting pollinators drawn to its sunny blooms.

Design tip
Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
