What is Dryopteris Marginalis?

- Vase-shaped clump: This fern grows in a tidy, non-spreading clump, making it ideal for smaller gardens.
- Deeply cut fronds: The fronds are a beautiful blue-green color and have a lacy, divided appearance.
- Sori on margins: The reproductive structures (sori) of this fern are located along the edges or margins of the fronds, hence the common name “Marginal Wood Fern.”
