Dyers Woad
Dyers Woad PNW0384   Colonists introduced this tall, bluish green plant, used as a source of blue dye since the 13th century. It is unpalatable to livestock, and is a noxious weed in Washington, Oregon, California, Idaho, and Utah. Photos of yellow-flowered plants, rosettes, fruits and seeds aid in identification. Biology, ecology, and cultural control are discussed.
