Abstract:
Oregon is a gardener’s dream. Our varied climates and mild conditions allow us to showcase a wide variety of plants from around the world. In fact, nursery crops are Oregon’s number one agricultural commodity.
Unfortunately, a few plants used in gardens and landscapes cause serious
ecological harm by ‘jumping the fence’ and spreading elsewhere. These
invasive plants can become serious problems that threaten water quality,
wildlife and our economy by crowding out native plants, changing stream
flows, increasing erosion, competing with crops or creating fire hazards.
