In brief: You can identify wild garlic by the strong garlic-like smell of crushed leaves, which is absent in lily of the valley. Wild garlic leaves grow individually on stalks from the ground and are matte green with a distinct underside. Lily of the valley always has two to three leaves per stem, which are glossier and grow in pairs from a shared sheath. The poisonous lookalike also produces white, bell-shaped flowers in May.
Wild Garlic & Lily of the Valley: How to Spot the Difference
The leaves of wild garlic and lily of the valley look remarkably similar. Misidentifying them can have serious consequences. Lily of the valley contains toxins that affect the heart. This guide explains the key identifying features.
You will learn how to identify both plants with confidence. We begin with the clearest distinguishing features.
The life-saving smell test
Rub a leaf between your fingers. Crush it gently. Genuine wild garlic immediately releases an intense, garlic-like smell.
Lily of the valley leaves do not smell of garlic. They have no smell or only a very faint grassy scent. This test is the first and most important step.
Important note
The smell of wild garlic stays on your hands. Always carry out the test on the first leaf. If you touch lily of the valley afterwards, you will transfer the scent and distort the result.
What exactly do the leaves look like?
Look at their shape, colour and texture. Wild garlic leaves are soft, matte green and have a distinct central vein. The underside of the leaf is duller than the top.
Each leaf grows from the ground on its own three-sided stalk. The stalks are clearly separate from one another.
Lily of the valley leaves are firmer, more leathery and often glossier. They are darker green on top. Typically, two, sometimes three leaves emerge from a shared, tube-shaped sheath on the same stem.
They wrap around the stem like a sheath. This is known as a “pouch-like” shape.
Comparing how they grow
Wild garlic grows in clumps or forms large, dense carpets. Where it grows, the air smells strongly of garlic. You can find it in moist woodland areas.
Lily of the valley often grows in smaller groups. It spreads through underground runners. It also thrives in drier, more open woodland and in gardens.
The risk of confusion is greatest in early spring, before the characteristic flowers appear. At that point, you must rely on the leaves, stalks and smell.
What are the differences between the stalks and flowers?
The stalk provides a reliable clue. Wild garlic has one individual, upright stalk per leaf. It is clearly three-sided in cross-section.
Lily of the valley leaves grow in pairs on a shared stem. This stem is round and enclosed by the two leaf sheaths.
The flowers are unmistakable. Wild garlic produces white, star-shaped flowers in a loose umbel from April to May. Each flower has six narrow petals.
Lily of the valley flowers from May to June. Its white, bell-shaped flowers hang along one side of a separate, leafless flower stem. This grows up between the two leaves.
Expert tip
Never pick whole clumps of leaves at once. Always take individual leaves and check each one separately. This prevents a lily of the valley leaf from ending up unnoticed in your harvest.
Location as a clue
Wild garlic prefers moist, nutrient-rich soil in shady deciduous woodland. It often grows near streams. The soil is rich in humus and loose.
Lily of the valley is less demanding. It grows in deciduous and coniferous woodland, at woodland edges and in many home gardens. It tolerates drier locations.
A strong garlic smell in the air is a clear indication that wild garlic is growing nearby. If this scent is absent, be especially careful.
Why is confusing the two plants so dangerous?
Lily of the valley contains glycosides such as convallatoxin. These substances act directly on the heart. They can cause life-threatening irregular heart rhythms.
All parts of the plant are poisonous, including the water in a vase of flowers. Symptoms of poisoning appear quickly: nausea, vomiting, diarrhoea, dizziness and drowsiness.
Even small amounts are dangerous. Children and pets are particularly at risk. If you understand the risks, you can forage with the necessary care.
For work in the garden, sharp, clean cutting tools such as the
or the .
Every year, we treat several serious cases of poisoning caused by plants mistaken for wild garlic. The people affected were often experienced foragers who had let their guard down for a moment. Absolute certainty is the only safeguard.
First aid if you suspect a mix-up
If you suspect that someone has eaten lily of the valley, stay calm. Bring any remaining collected or eaten plant material with you.
Contact a poison control centre or doctor immediately. Do not give water or milk to dilute it unless the expert on the phone advises you to do so.
Do not try to induce vomiting. Bringing a plant sample allows for quick and accurate identification.
Additional advice
Photograph the location and the plant before picking it, including the leaf, stalk and, if present, the flower. These images can later help experts identify it with certainty if any doubt remains.
How do I collect wild garlic safely and correctly?
Look for familiar, uncontaminated locations. Avoid busy dog-walking routes and areas close to roads. Pollutants accumulate in the leaves.
Only pick as many leaves as you need. Cut them off with a sharp knife or scissors such as the
. This helps protect the plant.
Do not pull them out, as you may damage the bulb in the soil. Always leave enough leaves for the plant to survive and reproduce.
Use your harvest on the same day. Wild garlic wilts quickly. You can use it fresh, make pesto or freeze it in portions.
Storing and using your harvest
Only wash the leaves shortly before using them. Wrap them in a damp cloth or place them in a glass of water with the stems submerged.
They will keep for one to two days in the fridge. Wild garlic loses its flavour when dried. Freezing is the best method for long-term preservation.
The fresh leaves are delicious in salads and soups, with quark or as a seasoning on buttered bread. Only heat them briefly, otherwise their distinctive flavour will evaporate.

Watch out for other poisonous lookalikes
Lily of the valley is not the only danger. Autumn crocuses flower in autumn, but their leaves appear in spring. They are deadly poisonous.
One distinguishing feature is that autumn crocus leaves have no stalk. They grow in a rosette directly from the ground. They are fleshier and shinier than wild garlic leaves.
Young leaves of spotted arum can also look similar. However, they are arrow-shaped and often have dark spots. All parts of spotted arum are poisonous.
The safest method is to collect wild garlic only where you know it with 100 percent certainty. If in doubt, leave it. Your health is worth it.
With the right knowledge and tools, such as those from our power tools range, you can tackle every gardening task safely.

- Can I rely solely on the smell test?
- No, relying on the smell test alone is risky. The smell of garlic stays on your hands. After touching wild garlic, any lily of the valley you pick afterwards will smell of garlic too. Always combine the smell test with checking the leaves and stems to identify the plant safely.
- When is the main season for wild garlic and lily of the valley?

- Yes. In addition to lily of the valley, autumn crocus and young, non-poisonous-looking spotted arum leaves can look similar. Autumn crocus is highly poisonous but has no stems – its leaves grow directly from the ground. Spotted arum has arrow-shaped leaves. Only collect wild garlic if you are absolutely certain.
- Where is wild garlic most likely to grow?
- Wild garlic prefers damp, humus-rich deciduous forests, floodplain woodland and shady stream banks. It often forms large carpets. Lily of the valley also grows in gardens, parks and lighter woodland. If you find individual plants without the typical strong garlic scent, take care.
