Each Spring, I visit some of the wetlands of the Indiana Dunes National Lakeshore in search of plants and animals. Of particular interest are ferns; more specifically, fiddleheads. Before the fern fronds appear, they develop in a circular roll, and slowly unroll to form a frond. These rolled up fronds are called fiddleheads, and look similar to their namesake, although I assume, the end of a violin was patterned after the fern.
No two are exactly the same, and they don't stay rolled up for very long. What amazes me is that each of the tiny leaves of the fern is an almost exact match to the unrolled fern frond. So, the fern is comprised of fronds that are comprised of fronds. Look closely and you'll see what I mean. A sure sign that winter is over.
