Whorled Loosestrife Flowers in Open Woods

Late May to early June is the blooming time for Whorled Loosestrife, Lysimachia quadrifolia in Pennsylvania, in particular South-central PA. These delicate loosestrife plants are about two feet tall and have lance-shaped leaves in whorls. You can find them flowering in open woods, at the edges of fields and along hiking trails.

Flower buds project well over the whorled leaves, one flower for each leaf.

Whorls have typically four leaves and flowers but on the mountain ridge here we often see whorls of five. More rarely plants will have whorls of three. Photo above taken 31 May 2010.

  1. I thought I had found the plant I was looking for when I saw your picture on Images when I Googled “vine with whorled leaves” but then found it is a tall plant. The plant I saw is a creeping ground vine that has whorled leaves spaced about 2 inches apart. It is mid August in Montana and the flowers are gone but in their place are several tiny fluffy seed pods that seem to come out of the center of the whorl. I can send a picture if that would help you identify this plant. I’m at a loss.

    Thank you.
