There are plenty of mid-spring herbs and greens in season. We'll find mugwort, a tonics for the female reproductive system. Since I've learned these herbs, I've never suffered a monthly cramp!
We'll also be finding Asiatic dayflower, common mallow, lady's thumb, lamb's-quarters, and goutweed, all great for salads, sandwiches, and soups.
Pokeweed is another seasonal potherb. It's superb boiled in 2 changes of water (it's poisonous raw!). Flavor it with tamari soy sauce and garlic lightly browned in olive oil, as in Basic Pokeweed.
Common milkweed also needs to be boiled, but only once. It has a flavor all its own, and we'll it loves agricultural fields.
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 flowers and tops of garlic mustard, which taste like garlic, and jewelweed, a panacea for skin irritations that cures mosquito bites and prevents poison ivy rash.
