Omnia SanaThis tool aids identification but does not replace an expert. Never eat a wild plant or fungus on the strength of a single feature. When in doubt, throw it out.
Garlic can be confused with 3 dangerous plants/fungi. Check every distinguishing feature before you trust an identification.
There is no antidote; the strap-shaped spring leaves are mistaken for wild garlic and the corm/flower for saffron. Poisoning is deceptively delayed (2–12 h) then causes catastrophic vomiting, organ failure and death.
Confusable part: Spring leaves, when foraging wild garlic (ramsons) foliage before flowering.
When people gather wild garlic (ramsons) leaves in spring, autumn crocus leaves - which emerge at the same time in the same damp meadows and woodland edges - are the deadliest thing they can pick by mistake. Autumn crocus contains colchicine, a cell poison with no reliable antidote; a few leaves can kill, and poisoning is repeatedly documented from 'wild garlic' that was actually autumn crocus, progressing from stomach upset to multi-organ failure.
How to tell them apart
- Crushed wild-garlic leaves smell strongly of garlic or onion; autumn crocus leaves have NO garlic smell.
- Each wild-garlic leaf grows singly on its own slender stalk; autumn crocus leaves are thicker, stiffer and glossy, several clasped together from a common base at ground level, with no individual stalks.
- Wild garlic pulls up with a small white bulb and onion-like roots; autumn crocus has no garlic bulb.
Crush one leaf with clean hands and smell it: a strong garlic or onion smell = wild garlic (safe); no garlic smell = do not pick it. Hands already smelling of garlic give false reassurance, so test with clean hands.
Whole plant is poisonous; its broad green spring leaves are notoriously confused with wild garlic (ramsons) before flowering, and ingestion can cause vomiting and serious, potentially fatal heart-rhythm disturbances.
Confusable part: Spring leaves, when foraging wild garlic (ramsons) foliage before flowering.
Lily-of-the-valley leaves emerge at the same time and in the same shady, damp woodland as wild garlic and are a classic, sometimes fatal, mix-up. The plant contains cardiac glycosides (convallatoxin) that disturb the heartbeat like an overdose of heart medicine, and there is no reliable antidote; foragers who ate leaves they took for wild garlic have arrived at hospital with a dangerously slow heart and low blood pressure.
How to tell them apart
- Crushed wild-garlic leaves smell strongly of garlic or onion; lily-of-the-valley leaves have NO garlic smell.
- Wild garlic has ONE leaf per individual stalk; lily-of-the-valley has a pair (sometimes three) of leaves wrapped together around a single common stalk, often purplish at the base.
- Lily-of-the-valley leaves are stiffer and glossier, and there is no garlic bulb underneath.
Crush one leaf with clean hands and smell: strong garlic or onion = wild garlic (safe); no garlic smell = discard. Then check the leaves - one leaf per separate stalk (wild garlic) versus a pair of leaves sheathed around one common stalk (lily-of-the-valley).
Biting into any part fires microscopic needle crystals into the mouth and throat, causing intense burning, swelling and blistering; severe swelling can threaten the airway. The arrow-shaped spring leaves grow among ramsons and other foraged greens.
Confusable part: Young spring leaves, when foraging wild garlic (ramsons) foliage.
Lords-and-ladies pushes up its young leaves at the same time and in the very same damp woods as wild garlic, often mixed in with it. Every part contains needle-like calcium-oxalate crystals: biting a leaf drives them into the mouth and throat, causing immediate intense burning, blistering and swelling - occasionally enough to threaten the airway.
How to tell them apart
- Crushed wild-garlic leaves smell strongly of garlic or onion; lords-and-ladies leaves have NO garlic smell.
- Wild-garlic leaves have parallel veins running the length of the leaf; lords-and-ladies leaves have a branching net of veins.
- Lords-and-ladies leaves are arrow- or spear-shaped with two backward-pointing lobes ('tails') at the base, often glossy and sometimes dark-spotted; wild-garlic leaves are smooth ovals with no basal lobes.
Crush one leaf with clean hands and smell: garlic or onion = wild garlic (safe); no smell = discard. Reject any leaf that is arrow-shaped with basal 'tail' lobes or has net-like (not parallel) veins - that is lords-and-ladies.
