Most of the plants we commonly refer to as "weeds" are not native to the Pacific Northwest. They are immigrants from Eurasia, the "Old World," brought here by good intentions or by accident. These plants are generally fast growing, tough competitors, and will grow in a wide range of soils. Most of them seed prolifically and some have pernicious underground rhizomes. Some of our worst weeds include thistles, tansy ragwort, knapweed, bindweed, quackgrass, puncture vine, wild oats, Kentucky bluegrass (actually native to the Old World), cheatgrass and medusa-head wild rye.
