Lance-leaved Loosestrife has burgundy to maroon delicate foliage appearing in spring. The small but plentiful yellow blossoms appear in early spring and continue throughout the summer, making an attractive crown to the dark foliage. Lysimachia lanceolata var. purpurea is a subtle but tough native ground cover, spreading by rhizomes in both full sun and light shade. The expanding patches of Lance-leaved Loosestrife function as weed suppressors.
