The internet is a wonderful thing. I was looking to identify a New England wildflower, and by following a series of links, I ended up at a site all about foraging, that is, hunting for food. With supermarkets and processed foods, we've gotten away from some of the nutritious "natural" foods that may be growing in our own backyard. The site, Josh's Journal: New England Natural History and Foraging, is a wealth of information!
In the section devoted to foraging, New England Wild Edibles Monthly Guide, you can find out what may be available to hunt and gather now in May. Dandelions, garlic-mustard tops, and violets are just three of the items you'll find outside today.
Here are three books in our collection that would be a good place to start your foraging adventures:
Richardson, Joan. Wild Edible Plants of New England: A Field Guide: Including Poisonous Plants Often Encountered. [581.6 RIC]
Rothman, Julia. Nature Anatomy: The Curious Parts & Pieces of the Natural World. [508 ROT]
Zachos, Ellen. Backyard Foraging: 65 Familiar Plants You Didn't Know You Could Eat. [641.303 ZAC]
We have a number of other edible wild plant guides in the 581.6 section.
