Common salsify (Tragopogon porrifolius) is another wildflower or noxious weed introduced from Eurasia. Also called oysterplant, this salsify closely resembles the yellow salsify (Tragopogon dubius) in my last post, with the main difference being common salsify is purple while yellow salsify is, well, yellow. Common salsify also tends to grow in moister habitats than its yellow cousin and its root is considered less bitter and fibrous, making common salsify more palatable. I have never eaten common salsify so cannot comment on its edibility. This plant was photographed in an empty lot in Ashland OR (Jackson County).
