Part of successfully growing a garden is knowing your USDA hardiness planting zone. USDA plant hardiness zones are the standard by which gardeners and growers can determine which plants are most likely to thrive at any given location. Some plants are able to survive outside of their hardiness zone, but can only survive for one growing season and are therefore considered annuals.
Oregon’s plant hardiness planting zones range from 4a, where winter temperatures can drop as low as -30 degrees Fahrenheit, to a hot 9a, where winter temperatures only drop to 25 degrees Fahrenheit.
