Sweetgale is a delightful Wisconsin native plant at home in moist to wet areas along wetlands, bogs, marshes, streambanks, and low-lying areas. An underused shrub with many benefits, Sweetgale has pink catkins in spring, followed by small, greenish-yellow to brown nutlets that persist into winter. In addition to fixing dinitrogen, Sweetgale provides great coverage and food for birds. To set fruit, one male must be present for every three females is required.
