Restoration and Conservation
Marsh cinquefoil tolerates cold latitudes and excels in ponds and lake marshes. The foliage at the surface and rooted stems can stabilize soil and slow down water. It is an attractive plant excellent to use for home water features, and the flowers provide nectar for bees and other pollinators.
Different parts of the plant have been used by Native Americans. The Chipewa/Ojibwe tribes used the roots in a decoction as an antidiarrheal and to treat stomach cramps. Alaskan tribes used the dried leaves and drank them as tea (no medicinal purpose, just as a cup of tea).
