A lot of plants are toxic when ingested, but some may even be dangerous when coming into contact with skin.

According to Fiona Jenkins, gardening expert at MyJobQuote.co.uk, the UK’s most dangerous plant is one to look out for.

She said: “The oleander plant is the UK’s most dangerous plant due to it being very toxic for both humans and animals.

“This plant is very poisonous, and if you ingest even a very small amount of this plant, it can result in death.

“Physical contact with the plant can cause allergic reactions and severe skin irritations. It’s important to keep oleanders away from children and pets.”

If you do have pets or children in the garden regularly, it’s best to avoid this plant at all costs despite its beauty.

They can be spotted by their clusters of funnel-shaped flowers, in colours including pink, white, red, coral or yellow.

Foxgloves are a gorgeous plant, often found in woodlands throughout the UK, with many people opting to have them in their gardens.

However, this plant contains toxic cardiac glycosides, according to Fiona, which can result in “serious poisoning”.

The expert continued: ”Deadly nightshade is a plant with purple and green flowers and untoothed oval leaves.

“It features several green berries that then ripen to a black colour. Every part of this plant is toxic, and the berries are particularly poisonous.

“Ingesting the berries can result in a range of side effects that can be very dangerous.”

As all parts of a lily plant can be toxic to animals, they should be avoided completely.

According to Fiona, if ingested, pets may suffer from kidney damage. The gardening pro added: “Unfortunately, this can be fatal. It's important to keep your pets away from lily plants.

“Lily pollen can easily fall onto your pet's fur, which they may then ingest when they groom themselves.”
