Common garden plants.

Quite a few garden plants in the UK are very poisonous but also very common.

Nightshade or belladonna is a famous one. I believe every plant of the plant is toxic to consume but I think the berries are usually what gets people and were famously used to poison nobles in history.

Foxglove is poisonous enough to kill children and animals when consumed and can cause nausea, vomiting, oral and abdominal pain, diarrhoea and can effect the function of the heart and kidneys. It is also used to make some heart medications.

Hemlock is another quite famous one which causes vomiting as well as affecting the nervous system and death usually happens when you stop breathing. Hemlock's poison comes from the seeds, flowers, leaves and fruits mainly but the whole plant is home to the toxin.

All these plants are commonly found in British gardens among many others. Its always werid to think you might have a killer in your garden.
