Last spring I purchased a healthy Caltha palustris in a one gallon pot from Scioto Gardens, a nursery that specializes in native plants. I planted my new purchase in the back corner of our 1/4 acre lot, in an area where water collects during rain events. This turned out to be the perfect location- I now have a dozen seedling marsh marigolds surrounding the parent plant.
If you're thinking that these flowers look more like buttercups- you must have a sharp eye for botany. The marsh marigold is in the plant family Ranunculacae along with the buttercups.
If you'd like your own marsh marigold, head to Scioto Gardens. If you're content with viewing one if Ohio's mist spectacular displays of this species, visit Fowler Woods State Nature Preserve in Richland County.
