DENDROLOGY

Detailed explanation-1: -Fern leaves are also known as fronds. When leaves first emerge they are often tightly coiled and called fiddleheads since they resemble the very top part of a fiddle instrument. The fronds arise from an underground stem known as a rhizome.

Detailed explanation-2: -Fiddleheads. As new fronds emerge, generally in the spring, they unroll, these unrolling fronds are called fiddleheads.

Detailed explanation-3: -What Are Fiddleheads? In April, young ferns sprout from wet soil, appearing bright green against the decaying leaves. These are fiddleheads, so-called because the very tops-furled tight when young-look like the tuning end of a fiddle.

Detailed explanation-4: -Fiddleheads, an early spring delicacy throughout the Northeast and Canadian Maritime Provinces, are the young coiled fronds of the ostrich fern (Matteuccia struthiopteris). Nearly all ferns have fiddleheads, but not all fiddleheads are edible.
