Persicaria virginiana is a vigorous perennial native to Missouri. It typically forms a spreading foliage mound 2-3 feet tall and as wide or wider. Broad, oval, medium green leaves. Tiny, white to greenish-white, beady, jumpseed-like flowers on long, slender, wand-like stems appear in mid to late summer, but are not particularly showy. Sheathed stem joints are a distinctive characteristic of all plants in this genus. Synonymous with and sometimes also sold as Polyganum virginianum or Tovara virginiana. Variegated cultivars are more commonly grown for their showy foliage.
Variegata Groups plants are primarily grown for its bold, variegated foliage. Ovate green leaves (to 5" long) are attractively splashed with white.
