Northern adderstongue is a tiny, uncommon native fern that grows just a few inches tall in shaded woodland areas. This diminutive plant produces a single small leaf and a distinctive spore-bearing stalk that resembles a small tongue or spike.

In an HOA neighborhood

Northern Adderstongue takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Extremely small and easily overlooked
  • May appear as weeds or bare spots
  • Very uncommon and unfamiliar to most people

Wildlife value

As a fern, this species does not attract pollinators but may provide minor habitat value for small woodland creatures and soil invertebrates.

Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
