This list of common poisonous plants that call some British yards home can be very dangerous. For example, animals who get lured to eat some colourful hydrangeas can experience vomiting, diarrhoea, and convulsions.
To humans, garden favourites like Lilies of the Valley and Wisterias can cause nasty rashes as well as vomiting when ingested. Among the sinister-sounding names are the Deadly Nightshade and Hemlock that can lead to the worst consequences — convulsion, hallucination, and even death.
Though most of these plants do not need to be eliminated, you need to have the proper knowledge in order to deal with them better.
Stalks of Rhubarbs make an excellent crumble recipe, but you should beware of the plant’s leaves. They contain high levels of oxalic acid, so when enough of the leaves are consumed, they can quickly cause kidney failure in humans.
Daffodils can add elegance to the garden, but if you have a dog who loves digging, you should keep it away from this flowering plant. Once eaten, dogs can experience vomiting, convulsion, and diarrhoea.
Found mostly in central, eastern, and southern parts of the UK, the Deadly Nightshade can cause dilated pupils, loss of balance, and skin rashes. These symptoms can even lead to convulsions and hallucinations.
Commonly found in ditches and on riverbanks, every part of the poisonous Hemlock — seeds, flowers, leaves, or fruits — contain toxic alkaloids that can be fatal even in small amounts. It can affect nerve impulse transmission to the muscles, paralysing a person’s lungs which undoubtedly leads to death.
In some cases, just getting in contact with Hemlock can cause skin reactions.
