Lady Fern
The Graceful Native Fern Every Minnesota Shade Garden Needs
Lady Fern (Athyrium filix-femina) is one of the most adaptable and beautiful native ferns for Minnesota shade — finely divided, bright green fronds form soft, arching clumps that bring a fresh woodland feel to any shaded bed. Tougher and more sun- and dry-tolerant than most ferns, it thrives in conditions that defeat fussier species. A reliable, deer-resistant choice for woodland gardens and shaded borders in Plymouth, Bloomington, and Shoreview.
