Whitworth considers rushes (Juncus), sedges (Carex) and redtwig dogwoods (Cornus sericea) the core workhorses for wet winter and dry summer situations. She also finds that many Pacific Northwest native plants work well, especially those that naturally grow along the edges of streams and wetlands. Non-native plants that grow in similar conditions are also excellent choices. Many wetland plants multiply readily from seed, rhizomes (horizontal underground stems) or suckers (new shoots produced from roots or underground stems). That’s good news if you have limited funds for plants and lots of garden space to fill but bad news if your space is small. Select plants not just by appearance and cultural requirements but with an eye toward their reproductive nature and vigor.
