n Harvesting Wild Edibles for wild edible plants provides “ Foraging opportunities to be attentive to your surroundings. Whenever we slow down enough to really see a plant, to take in its form or fragrance, that’s when we are likely to see the most amazing caterpillar, or find a warbler’s nest hiding in the thicket. For me foraging is as much about keeping my senses honed, my observational skills sharp; and in touch with the wilder, perhaps more primal part of myself, as it is about adding fresh, nutritional, and very local food to my diet.
”
Considerations for Harvesting Wild Edibles Be respectful! Harvest judiciously, leaving some for other people, and for wildlife. Get permission if harvesting on other peoples’ property. Acquaint yourself with the poisonous plants in your area,
especially those that may resemble something you may wish to harvest. Be especially cautious with members of the carrot family. Wild carrot (an edible) may resemble poison hemlock and water hemlock both can be deadly.
Make sure you positively identify any plant before eating any part of it. Just because it’s
“natural” doesn’t mean it’s safe.
Learn which parts of the plant you can eat. Many plants have
poisonous and edible parts. Some like poke accumulate toxins as they mature. Read up before eating up!
Know how to safely prepare your harvest before you eat it. For
example, elderberries should be either cooked or made into wine before consuming.
Consider the area where you are harvesting. How safe is it?
Has the area been sprayed with herbicides or pesticides? Is the plant growing in polluted water or soil? Busy road sides are often contaminated.
Don’t eat too much of any new food. Some people are
extremely allergic to certain foods, and wild foods are no exception. Most allergic reactions are mild, but if you tend to have lots of food allergies your chances may be greater for an adverse reaction, including a serious one.
Don’t eat wild edible plants if you are pregnant or taking medications. Plants are
“chemical factories” and to be on the safe side, it’s best not to risk some unexpected chemical interactions.
Don’t rely on only one person, one book or one website for your knowledge about wild edible and poisonous plants. Enjoy the research and the search!
Don’t rely on common names when doing your research on plants you plan to harvest.
While you don’t need to start speaking “botaneze’ you will want the plants you investigate to be the same plants throughout your research.
Be cautious when presenting wild edibles around children.
Harvesting wild edibles can provide fun and food for the family, but be aware that very young children may not be able to make the important distinctions between similar looking plants.
Don’t assume something is safe to eat just because you watch some little animal eat the plant.
Many animals can handle toxins that we can’t.

n Harvesting Wild Edibles Curly Dock
(Rumex crispus)
Edible parts:
Young leaves and shoots, cooked as you would chard or kale; and (milled) seeds, which are similar to amaranth.
Harvest time:
Leaves and shoots spring and early summer. Seeds in fall and winter.
Where found:
Gardens and disturbed areas.

n Harvesting Wild Edibles Daylily
(Hemerocallis fulva)
Edible parts:
Buds, flowers (fresh or dried), tubers. I like stir-frying the buds and serving them over rice. A dash of soy sauce, sesame seed oil and hot chili oil are great options. Garnish with a fresh blossom!
Harvest time:
Buds and blossoms, mostly in June and July. The small tubers can be harvested any time the ground isn’t frozen. I recommend cooking them as you would very small potatoes.
Where found:
Roadsides, old farms and gardens. Beware that those on roadsides may be contaminated with sprays or automobile exhaust.

Elderberry
(Sambucus canadensis)
Edible parts:
Flowers, ripe berries cooked in jams and jellies or fermented (not raw). Do not mistake this plant for either water or poison hemlock, which are both very toxic! The flower heads of both look superficially similar.
Harvest time:
Flower clusters for making fritters and for elderflower “champagne” in early summer. Berries, late summer.
Where found:
Old gardens, edge of woods and thickets and country roads.

Lamb’s-quarters
(Chenopodium album)
Edible parts:
Cooked young leaves and shoots. Remove any tough stems or large, tough leaves. The leaves have a gritty white layer that cooks off quickly in a bit of water. Use as you would cooked spinach — in quiche, perhaps.
Harvest time:
Spring and summer, for as long as you find tender leaves.
Where found:
Gardens and other places with disturbed soil, construction sites, etc.

Lamb’s-Quarter Salad Gather about 12 cups of lamb’s-quarters (wild spinach) leaves and growing tips. Pick through this harvest to remove tough stems and any spoilage. You should have 6–8 cups of lamb’s-quarters. Place these in a large colander and rinse well with cold water. Bring approximately ½ cup of water to boil in a medium saucepan. Add a pinch of salt and toss in the greens and stir. The leaves should turn bright green. Cook just 2 or 3 minutes, until tender. Lift greens from pan with a slotted spoon and toss them in a bowl of ice water to stop the cooking. Gently squeeze the liquid from the leaves (save for soup stock if you like) and place this lovely green mass of leaves in a medium bowl and add dressing.
Dressing:
Whisk together the following ingredients and adjust to taste. 1½ t ablespoons fresh lemon juice or rice vinegar 2–3 teaspoons soy sauce 1–2 tablespoons sweet chili sauce ¼ cup light olive oil ¼ teaspoon toasted sesame seed oil Drizzle some of this dressing over the cooked, drained and cooled leaves. Add toasted crushed peanuts. The greens will cook down considerably. This should be a nice side dish for 2.
