Instructions
Step 1: Learn the ground rules
Agent action: Before identifying any plant, establish these non-negotiable principles. Skip this at your own risk.

RULE #1: 100% CERTAIN OR DON'T EAT IT. No exceptions. No "pretty sure." No "it looks like the picture." 100% positive identification or you walk away. The consequences of getting this wrong range from vomiting to organ failure to death.

RULE #2: USE MULTIPLE IDENTIFICATION FEATURES. Never identify a plant by a single characteristic. Use at least 3-4 features: leaf shape, leaf arrangement, stem shape, flower color and structure, smell, habitat, season.

RULE #3: KNOW THE DANGEROUS LOOKALIKES FIRST. For every edible plant, know what it can be confused with. Learn the dangerous plants BEFORE learning the edible ones.

RULE #4: START WITH THE EASY ONES. The 15 plants in this skill were chosen because they're common, easy to identify, and have no deadly lookalikes (or the lookalikes are obvious to distinguish). Start here. Stay here until confident.

RULE #5: LEARN FROM A LOCAL EXPERT. Books and apps get you started. A local foraging walk with an experienced guide teaches you more in 2 hours than a year of reading. Find one through: mycological societies, native plant societies, extension offices, community colleges, local foraging groups on Facebook/Meetup.

RULE #6: SUSTAINABLE HARVESTING.

Step 2: The 15 near-universal safe edibles
Agent action: Ask the user's location/climate zone first. Confirm which of these are present in their region before proceeding. All 15 are found across most temperate zones in North America, Europe, and parts of Asia/Oceania.

1. DANDELION (Taraxacum officinale) WHERE: everywhere. Lawns, fields, roadsides, cracks in pavement. PARTS: entire plant is edible — leaves (salad), flowers (fritters, wine), roots (roasted as coffee substitute) SEASON: spring for tender leaves, flowers in spring-summer ID: rosette of deeply toothed leaves, single hollow stem per flower, yellow flower, milky white sap LOOKALIKES: cat's ear (Hypochaeris) — also edible, so no risk

2. COMMON PLANTAIN (Plantago major) WHERE: lawns, paths, disturbed soil. One of the most common "weeds" worldwide. PARTS: young leaves (salad or cooked), seeds SEASON: spring-fall ID: broad oval leaves with parallel veins, grows in a rosette, tall flower spike with tiny flowers NOTE: not related to the banana-family plantain

3. WHITE CLOVER (Trifolium repens) WHERE: lawns, fields, everywhere grass grows PARTS: flowers (raw or dried for tea), young leaves SEASON: spring-fall ID: three round leaflets with white chevron marking, white spherical flower heads NOTE: red clover (Trifolium pratense) is also edible

4. CHICKWEED (Stellaria media) WHERE: gardens, lawns, disturbed soil, shady spots PARTS: entire above-ground plant (salad, sandwich green) SEASON: early spring and late fall (prefers cool weather) ID: small oval leaves in opposite pairs, tiny white flowers with deeply split petals (look like 10 petals but actually 5 split), single line of hairs along the stem (alternating sides) TASTE: mild, like lettuce

5. LAMB'S QUARTERS (Chenopodium album) WHERE: gardens, disturbed soil, agricultural edges PARTS: young leaves and tips (cooked like spinach — one of the most nutritious wild greens) SEASON: spring-summer ID: diamond-shaped leaves with irregular teeth, white powdery coating on young leaves, grooved stem NUTRITION: more iron, calcium, and protein than spinach

6. WOOD SORREL (Oxalis species) WHERE: forests, gardens, shady areas PARTS: leaves, flowers, seed pods (all raw — tart lemon flavor) SEASON: spring-fall ID: three heart-shaped leaflets that fold along the center crease, small 5-petaled flowers (yellow, white, or pink depending on species) NOTE: not related to sorrel (Rumex) — different plant family entirely CAUTION: high in oxalic acid. Eat in moderation (small amounts fine; don't make it your entire diet)

7. BLACKBERRIES / RASPBERRIES (Rubus species) WHERE: forest edges, roadsides, disturbed areas, hedgerows PARTS: berries (raw, jams, pies), young leaves (tea) SEASON: summer-early fall ID: thorny canes, compound leaves in groups of 3-5, white flowers, aggregate berries. Blackberries = fruit doesn't separate from core. Raspberries = fruit is hollow (separates from core). NOTE: there are no deadly berry lookalikes in this genus

8. ELDERBERRIES (Sambucus nigra / S. canadensis) WHERE: forest edges, stream banks, roadsides PARTS: berries (COOKED ONLY — raw are mildly toxic), flowers (fritters, cordial, tea) SEASON: flowers in spring, berries in late summer ID: compound leaves with 5-7 toothed leaflets, flat-topped clusters of tiny white flowers, clusters of small dark purple-black berries WARNING: raw berries cause nausea. Cook or dry them. CRITICAL: do NOT confuse with water hemlock or pokeweed berries

9. CATTAIL (Typha latifolia) WHERE: marshes, pond edges, ditches, anywhere with standing water PARTS: nearly everything — young shoots (spring, like hearts of palm), pollen (flour supplement), rhizomes (starchy, can be processed like potato) SEASON: year-round depending on part ID: tall (4-8 ft), flat strap-like leaves, distinctive brown cylindrical seed head ("corn dog on a stick") WARNING: do NOT confuse with iris (which grows in similar habitats and has similar leaves but no cattail seed head). Iris is toxic.

10. WILD GARLIC / RAMPS (Allium species) WHERE: forests, moist woodland, stream banks PARTS: leaves, bulbs (use like garlic or onion) SEASON: early spring (ramps are one of the first spring greens) ID: broad, smooth leaves emerging from a bulb, strong garlic/onion smell when crushed THE SMELL TEST: if it smells like garlic or onion, it's an Allium. If it doesn't smell like garlic/onion, PUT IT DOWN. Lily of the valley (deadly) looks similar but has NO onion/garlic smell.

11. PURSLANE (Portulaca oleracea) WHERE: gardens, sidewalk cracks, disturbed soil, hot dry areas PARTS: stems and leaves (raw in salads or cooked) SEASON: summer ID: succulent (thick, fleshy) red stems, small paddle-shaped fleshy leaves, grows low to ground NUTRITION: highest omega-3 fatty acid content of any leafy green WARNING: spurge (Euphorbia) looks vaguely similar but has milky sap (purslane has clear sap) and thinner, non-succulent leaves

12. ROSE HIPS (Rosa species) WHERE: wherever wild roses grow — hedgerows, forest edges, fields PARTS: the fruit (the red/orange bulb left after the flower drops) SEASON: fall (after first frost they sweeten) ID: the small round or oval fruit of any wild rose. If the plant had roses, the hips are edible. USE: tea (slice open, remove seeds and hairs, steep), jam, syrup NUTRITION: extremely high in vitamin C (20x more than oranges by weight)

13. ACORNS (Quercus species) WHERE: wherever oaks grow (nearly everywhere in temperate zones) PARTS: the nut (after processing) SEASON: fall PROCESSING REQUIRED: acorns contain tannins that are bitter and can cause nausea. Leach the tannins: shell acorns, grind or chop, soak in water (change water repeatedly until bitterness is gone — takes several water changes over 1-2 days, or use running water). White oak group acorns have less tannin and leach faster. USE: flour (dried and ground), porridge, roasted

14. PINE NEEDLE TEA (Pinus species) WHERE: wherever pine trees grow PARTS: needles (for tea) SEASON: year-round (best in spring when needles are young) ID: needle-like leaves in bundles (fascicles). Confirm it's a true pine (Pinus genus) — needles come in bundles of 2, 3, or 5. AVOID: yew (Taxus — flat needles, not in bundles, red berries — EXTREMELY toxic). Norfolk Island pine and Ponderosa pine should be avoided by pregnant individuals. USE: steep a small handful of fresh needles in hot water 10-15 min. High in vitamin C.

15. STINGING NETTLES (Urtica dioica) WHERE: moist forest edges, stream banks, disturbed soil PARTS: young leaves and tips (COOKED — cooking neutralizes the sting) SEASON: early spring (harvest before flowering) ID: opposite serrated leaves, square stem, covered in fine stinging hairs HARVEST: wear gloves. The sting is immediate on bare skin. USE: cook like spinach (sauteed, in soups, as tea). Extremely nutritious — high in iron, calcium, and protein.

Step 3: Deadly plants to know
Agent action: These are the ones that kill or seriously injure. Knowing what NOT to eat is more important than knowing what to eat.

WATER HEMLOCK (Cicuta species):

POISON HEMLOCK (Conium maculatum):

DEADLY NIGHTSHADE (Atropa belladonna):

DEATH CAMAS (Zigadenus / Anticlea):

FOXGLOVE (Digitalis purpurea):

THE RULE OF UMBRELLA FLOWERS: Plants in the carrot/parsley family (Apiaceae) with umbrella-shaped white flower clusters include some of the deadliest plants on Earth AND some common edibles (carrots, parsley, fennel). Unless you are an experienced forager who can confidently distinguish these species, AVOID ALL wild plants with umbrella-shaped white flower clusters. This single rule eliminates the most common fatal foraging mistakes.

Step 4: The universal edibility test (last resort only)
Agent action: Include this for completeness but emphasize it's a survival-only protocol, not a foraging technique.

This is NOT a foraging method. This is a last-resort protocol for wilderness survival when you have no knowledge of local plants. It takes 24+ hours and may still fail for some toxins.

DO NOT USE THIS IF:

AVOID ENTIRELY (do not test):

THE TEST (8-hour minimum per plant part): 1. Test only one plant part at a time (leaf, stem, root, fruit) 2. Smell: crush and smell. Bitter almond = discard. Strong chemical smell = discard. 3. Skin contact: rub on inner wrist. Wait 8 hours. Any reaction (rash, redness, burning, numbness) = discard. 4. Lip test: touch to your lip for 15 minutes. Any tingling, burning, or numbness = discard. 5. Tongue test: place on your tongue for 15 minutes. Do not swallow. Any bad reaction = spit, rinse, discard. 6. Chew test: chew and hold in mouth 15 minutes. Do not swallow. Any bad reaction = spit, rinse, discard. 7. Swallow test: eat a small amount. Wait 8 hours. No negative effects = probably safe for that plant part. 8. Eat a larger portion. Wait another 8 hours.

Step 5: How to learn locally
Agent action: The 15-plant list is a starting point. Real foraging competency comes from local knowledge. Help the user find local resources.

FIND A LOCAL GUIDE:

GET FIELD GUIDES FOR YOUR REGION:

USE APPS AS A SUPPLEMENT (never sole identification):

A NOTE ON MUSHROOMS: This skill does NOT cover mushroom foraging in detail on purpose. Mushroom identification requires hands-on learning from an experienced local mycologist. The consequences of misidentification are severe (liver failure, death). Some common edibles have deadly lookalikes that differ by subtle features impossible to convey in text. If you want to forage mushrooms: 1. Join a local mycological society 2. Learn from an expert in the field, not from photos 3. Start with species that have no dangerous lookalikes (chicken of the woods, morels — and even these have caveats) 4. Get every identification confirmed by an experienced forager until you have years of practice

Step 6: Seasonal availability and planning
Agent action: Ask the user's region and provide a seasonal calendar. This example is for temperate Northern Hemisphere.

EARLY SPRING (March-April):

LATE SPRING (May-June):

SUMMER (July-August):

EARLY FALL (September-October):

LATE FALL - WINTER:

SOUTHERN HEMISPHERE: Shift all seasons by 6 months. March = early fall. September = early spring.

If This Fails
Can't positively identify a plant: Don't eat it. Photograph it from multiple angles (whole plant, close-up of leaf, stem, flower, habitat) and submit to iNaturalist for community identification. Wait for expert confirmation.
Ate something and feeling sick: Call Poison Control immediately. US: 1-800-222-1222. UK: 111. AU: 13 11 26. Keep a sample of what you ate. Note the time of ingestion and symptoms.
No local foraging groups: Check iNaturalist for active users in your area — message them. Look for native plant societies. Ask at your local library. Extension offices sometimes connect you with local experts.
Plants in your area aren't on this list: These 15 were chosen for global distribution, but your region has dozens of edibles not listed here. A regional field guide and a local foraging walk are the best next steps.
Rules
100% identification certainty or you don't eat it. This rule has no exceptions.
Never forage from areas treated with pesticides, herbicides, or near heavy traffic (lead and pollutant absorption).
Never trust a plant identification app as your sole source. Use it as a starting point, then confirm with field guide features and ideally a local expert.
Take only what you need and never more than 1/3 of any stand. Sustainable harvesting means the patch is there next year.
Do not forage mushrooms based on this skill file alone. Mushroom identification requires in-person training with a local expert.
Know your local foraging laws before harvesting on public land.
Tips
The "smell test" for the Allium family (garlic, onion) is the single most useful safety check in foraging. If it looks like wild garlic/onion and smells like garlic/onion, it's safe. If there's no smell, it might be lily of the valley or death camas. Walk away.
The three easiest first forages: dandelion (you already know what it looks like), blackberries (obvious and delicious), and clover (in every lawn). Start with these to build confidence.
Foraging near your home is better than foraging in the wilderness. You can observe the same patches through seasons, watch them grow, and learn their full life cycle. This builds real identification skill.
Young plants and early growth are almost always more tender, more flavorful, and easier to prepare than mature plants. Dandelion in March vs July is two completely different eating experiences.
A single foraging walk with a local expert will teach you more than 6 months of book learning. The sensory experience of touching, smelling, and seeing plants in context is irreplaceable.
