Clearweed is a member of the nettle family and it comes up all over the country. The easiest way to identify the plant is by the little white flowers that grow along its stem. There really isn't anything wrong with the plant but it is a weed that covers up other stuff in the garden. An interesting point about it is that it pollinates by the wind. So when the wind blows the seeds of the plant are blown about. You will typically find it growing in clusters because it is blown by the wind. Four butterflies feed on this plant including Milbert's Tortoiseshell, Polygonia Comma, Polygonia Interrogationis, and Red Admiral.
