(Humulus lupulus) A high alpha acid bittering-type hop used for adding body and flavor to all styles of beer. No other vine is faster growing or more effective as an ornamental screen. Plants can grow up to 20 feet in one year when grown in a sunny location and are easily trained on a fence or trellis. Each year they die back to the crown in winter. In late summer they bear cone-like flowers that have a fresh, pine-like fragrance. The flowers are used in beer-making. Dark green, deeply lobed foliage is very attractive.
