Growth happens so quickly this time of year. Little bumps unfurl until they are leafy ferns.
In forests, people pick the early fern shoots known as fiddleheads (usually the ostrich fern). They are quite tasty. They have to be cleaned well and then cooked thoroughly. As only the tightly furled shoots are edible, harvest season is short.
Here's a link to Fiddlehead recipes as well as information about picking them (I let mine grow and buy fresh fiddleheads at the grocery store).
