1. Surprisingly, the answer is (c) – all of a daffodil is poisonous.

2. Answer (b) – the seeds of Laburnum.

3. (b) – Yew is an evergreen, with small, needle-shaped leaves and bright red seed pods.

4. The answer is (a). Exposed skin turns red and itchy, and in about two days, blisters form, which can leave scars that last for years, while sap in the eyes can cause temporary – and sometimes permanent – blindness. Definitely one to avoid!

5. It’s (c) – all of them. All of these plants feature on the RHS list.

6. Although all of these symptoms can occur, depending on the plant eaten, the most common signs of poisoning are stomach pains, vomiting or diarrhoea – so it’s answer (a).

7. It’s (b) – the Horticultural Trade Association; garden centres that are members of the HTA display labels clearly warning of the dangers of common irritant, poisonous or potentially allergy-provoking plants.

8. Actually, they’re all true. The nightshade family contains a number of well known plants, including chilli peppers, petunias, mandrakes – and potatoes and tomatoes. Its scientific name Atropa belladonna comes from the Italian bella donna – “beautiful lady” – which is said to refer to its use to dilate the pupils to make eyes more appealing. Livia was, by all accounts, a prolific and proficient poisoner who would have been well aware of the effects of this plant. In one version of the story, she is supposed to have poisoned some of the food on her own plate, which she then offered to her husband – presumably to avoid his official “taster.”

So how did you do? Can you spot a poisonous plant a mile off, or do you need to do a bit more research?

Whether you’re an expert or a bit of a beginner, one thing’s for sure – you can never be too aware of the dangers that lurk in your garden. Always remember that old proverb – forewarned is definitely forearmed!
