Greek Valerian (Jacob’s Ladder)
Cynoglossum virginianum, also known as the wild comfrey, is a plant native to North America. It is also sometimes called the blue houndstongue. The drooping, tubular, pink flowers of Common Comfrey are a familiar sight to many gardeners. Sometimes considered a 'weed', this hairy plant can be used as an organic fertilizer and a form of slug control.
