Plants come in thousands of different varieties, and it can be tempting to go for the pretty flowers, but they could be dangerous.

1. Deadly nightshade

Fiona Jenkins, gardening expert at MyJobQuote.co.uk, said: “The deadly nightshade is a plant with purple and green flowers and untoothed oval leaves.

“It features berries that are green and then ripen into a black colour. All parts of this plant are toxic and the berries are particularly poisonous.

“Ingesting the berries can affect the nervous system and also cause difficulties with breathing, confusion, vomiting, sweating and hallucinations.”

2. Lords-and-ladies

This plant is a shade-loving plant, often found in woodlands and hedgerows, however, it still can be found in some gardens.

Recognised by its red berries, this plant features large, arrow-shaped leaves with purple spots.

The expert explained: “It features green, orange or red berries, depending on how ripe they are. All parts of this plant can cause reactions.

“However, the berries are particularly poisonous. The small needle-shaped crystals contained within this plant can cause severe skin irritations.

“Ingesting the plant can cause breathing difficulties, throat swelling, and can irritate the stomach.”

3. Monkshood

According to the gardening expert, monkshood is one of the most poisonous plants found in the UK towards animals and humans.

Fiona noted: “It features hooded flowers in various colours, making it very pretty to look at, resulting in it being a popular garden plant.

“All parts of this plant are poisonous. If any parts of the plant are ingested, it can cause dizziness and stomach pains.

“The poison in this plant can also affect the heart and may result in death if large amounts are ingested.

“It’s important to wear gloves when handling this plant as the toxins can enter the body through cuts and scrapes.”

4. Poison hemlock

Poison hemlock can often be found at the roadside, in ditches, or near streams and consumption of even a tiny amount can be possibly fatal.

It can be recognised by its tall height with hollow purple-blotched stalks which can be spotted from quite far away.

Fiona added: “If you have children or pets in your garden regularly, it’s best to stay away from this plant. This is the safest thing you can do to protect your family and pets.”
