Slowly unrolling each Spring, the ferns of Cowles Bog put on an interesting show for a few days while turning into full-length fronds. Once opened, the fronds hide any new fiddleheads, so this is the perfect time to see them.
What always intrigues me is how the center of the rolled up fiddlehead has groups of leaves that each appear to be miniature versions of full fern fronds. Only about the diameter of a nickel, these curled creations pack a dollar's worth of detail inside.
Cowles Bog is one of the few places I've come across where so many ferns can be seen in such close proximity. Hundreds of clumps are visible from the trail; I wonder how many are hidden from view.
