Most roots are out of season, but burdock, an expensive detoxifying herb sold in health food stores, is an exception, and it abounds in human-disturbed areas throughout the farm. Instead of brewing it as a tea, it's so abundant, you cook the root like a potato.
We'll also be finding Asiatic dayflower, common mallow, lady's thumb, lamb's-quarters, and goutweed, all great for salads, sandwiches, and soups.
Sassafras root, the original source of root beer, stays in season all year. You use it for tea, for making root beer, and as a cinnamon-like seasoning. It grows in the woods, and in thickets.
Another tree we'll look for in the woods is the black birch tree. You can steep the twigs in hot water to make a fabulous tea, with anti-inflammatory properties similar to aspirin. Or thicken the tea with agar, season and sweeten it, and make black birch Jello!
We'll also hunt for the seeds of garlic mustard, which taste like garlic, and jewelweed, a panacea for skin irritations that cures mosquito bites and prevents poison ivy rash.
