Riverbend Park ferns

stop and talkKit Sheffield led a ferns workshop last Sunday (yes, it’s been a busy week). We looked at a lot of ferns, some plants that don’t look like ferns but are, and of course some plants that aren’t ferns. We started at the Visitor Center, followed the river trail as far as Gladys Island and Carper’s Pond, then looped back via the Nature Center.

A few fern ID tips:

  • The first thing to look for is growth pattern: does this fern grow in a clump, or singly?
  • Look at the bottom pair of leaflets, for instance to distinguish Lady Fern from Hay-scented Fern. This is also useful for applying my “opposite Onoclea” rule.
  • Look for hairs in the axils (armpits) of Cinnamon Fern.

scourSomething that didn’t look like a fern for centuries, but is now considered to be one, based on fossil evidence: Scouringrush (Equisetum hyemale). Unfortunately for the quality of the image, the growth tips of this specimen have been deer-browsed.


rockyOne more fern, Rock Polypody (Polypodium virginianum). Cute name, cute fern!
