SGUK Outdoor Skills Challenge 17: Identify Three Edible-Looking Plants You Should Not Eat

Some wild plants look harmless, and a few even resemble familiar foods you might find in a supermarket or garden. The problem is that appearance alone cannot tell you whether a plant is safe to eat. Some poisonous species look similar to edible plants, and getting an identification wrong can have serious consequences.

For the SGUK Outdoor Skills Challenge 17, you’ll learn to recognise three dangerous British plants that people should never eat based on a casual identification: hemlock, foxglove and deadly nightshade. You’ll study their identifying features and learn why responsible foraging always starts with caution.

Your Challenge

Identify three wild plants that may be mistaken for something harmless or edible, and explain what makes each one dangerous.

You’ll use photographs or observe the plants from a safe distance, learn their distinguishing features and create a simple reference sheet. Do not taste, chew, handle or collect unknown plants to complete this challenge. You do not need to touch a plant to study it.

What You’ll Need

• A notebook and pen
• Reliable British plant identification guides or trusted botanical resources
• Clear photographs of hemlock, foxglove and deadly nightshade
• A camera or phone for photographing plants from a safe distance

Take the Challenge

Step 1: Learn to recognise hemlock

Hemlock (Conium maculatum) is a highly poisonous plant that can grow along hedgerows, roadsides, field edges and damp ground. It can resemble other members of the carrot family, which includes edible species, making casual identification particularly dangerous.

Look for features such as its tall, branching stems, finely divided leaves and clusters of small white flowers. The stems often have purple blotches, although markings can vary. Never rely on one feature alone, and do not handle the plant to inspect it.

Step 2: Study foxglove

Foxglove (Digitalis purpurea) is a familiar British wildflower with tall spikes of tubular, often pink-purple flowers. It may also have white or other colour variations. Its broad leaves form a low rosette before the flowering stem develops.

Foxglove contains compounds that can seriously affect the heart. Its leaves should never be eaten or used to make homemade remedies. Study photographs showing the leaves and flowers together, rather than relying on flower colour alone.

Step 3: Recognise deadly nightshade

Deadly nightshade (Atropa belladonna) is a poisonous plant with oval leaves, bell-shaped flowers and rounded berries that become dark purple-black when ripe. The berries may look tempting, particularly to children, but eating them can cause severe poisoning.

Learn to recognise the combination of its leaves, flowers and berries. Do not pick or handle the berries, and never assume that a wild berry is safe because it looks similar to something edible.

Step 4: Compare the three plants

Create a small identification sheet with the plant name, a photograph, its key features and a warning about its toxicity. Include at least two identifying features for each plant, but remember that these notes are for recognition and awareness, not proof that an unfamiliar plant has been identified correctly.

Step 5: Learn the safe response

If you find a plant that you cannot confidently identify, leave it alone. Don’t taste it to check whether it is edible, and don’t rely on a phone app or a single photograph to make a foraging decision. Some toxic plants resemble edible species closely, and mistakes can be fatal.

Safety

Never eat, taste or handle a plant as part of this challenge. Hemlock, foxglove and deadly nightshade are poisonous, and other dangerous species may resemble edible plants. Keep children and pets away from unknown plants, and wash your hands if you accidentally touch plant material.

If you think someone has eaten a poisonous plant, seek urgent medical advice. Do not wait for symptoms or try to make the person vomit. In the UK, call 999 if they have severe symptoms, collapse or are seriously unwell; otherwise, contact NHS 111 promptly for advice. Keep a photograph or note of the plant’s location if this can be done safely, but do not delay getting help to identify it.

Check Your Results

Before completing the challenge, make sure you can answer these questions:

• What are the three poisonous plants you’ve studied?
• What identifying features can help you recognise each one?
• Why is it dangerous to rely on just one feature or a photograph?
• Why should you never taste a plant to confirm its identity?
• What should you do if you suspect someone has eaten a poisonous plant?

You should be able to explain the main identifying features and the risks associated with each plant without touching or tasting them.

Complete the Challenge

To complete Challenge 17, prepare a reference sheet showing all three plants, their key identifying features and why they must not be eaten. You can use photographs from a reliable identification resource or take your own pictures from a safe distance.

Your evidence should show that you’ve learnt to recognise the risks, not that you’ve handled or collected poisonous plants.

How to Submit Your Challenge

1. Go to your SGUK member profile.
2. Open the Social Activity area.
3. Upload a photograph of your identification sheet or notes to your activity wall.
4. Add the hashtag #SGUKChallenge17.
5. Share your post for evidence verification.

Once you’ve shared your evidence and it has been verified, the SGUK Outdoor Skills Challenge 17 is complete and the completed challenges figure will be updated on your profile.

Challenge 17 Checklist

Want to Push Yourself?

Choose two additional poisonous or potentially harmful plants found in Britain and research how to recognise them safely. Add them to your reference sheet using photographs from a reliable botanical source.

Remember that this is a learning exercise, not a licence to forage. Before eating any wild plant, you need a reliable, positive identification based on the whole plant and appropriate expert knowledge. If there is any doubt, do not eat it.
