Beck's water marigold is an aquatic or wetland perennial that produces bright yellow daisy-like flowers from July through September. This plant requires consistently wet conditions and is best suited for pond edges, rain gardens, or naturally soggy areas where few other plants will thrive.
In an HOA neighborhood

Works well in: backyard only.
