A classic (typical) Ostrich Fern.
Classic Ostrich Fern shape and growth form. Note that this one is in standing water. They will grow in wet areas if the area is only wet for a while in the spring. This photo was taken at the end of May.
Nice patch of Ostrich Fern in a clearing in the woods.
Note how all the fronds/stalks grow from a single point - a black knob.
Here's a closeup view of this black knob. This is in mid-April, before the fiddleheads start to grow.
Ready to pick and eat. Ostrich Fern is common enough that its fiddleheads can be harvested for personal use without worrying too much about eradicating the species. Of course, prudence is always in order when harvesting any wild plants.
Too far gone to eat.
