Horticulture

What do you get combining abundant water from the Umpqua River and warm sunny days with cool nights? A wonderful place to grow high quality tree fruit, winegrapes, berries and melons. Our mild winter temperatures also allow gardeners to grow a wide variety of ornamental plantings. Most of the 100 Valleys of the Umpqua have either a zone 7 or 8 USDA plant hardiness rating.
