Japanese Knotweed is just one plant that could cause problems in your garden this summer.
It wreaks havoc as, at its most prolific, it can grow up to 20cm a day, can grow through concrete and tarmac and it's roots can grow as deep as three metres.
These aspects mean the weed can grow unabated, over taking other plants and leaving them without any light.
And although it doesn't produce any seeds, Knotweed can grow from minuscule fragments of rhizomes - the underground network of stems and roots - meaning it spreads seasily.
Below are nine of the most troublesome plants and how you can spot and deal with them.
Giant hogweed contains toxic chemicals which react with light when in contact with human skin, causing blistering within 48 hours.
Effectively it prevents the skin from protecting itself from sunlight, which can lead to very bad sunburn and scarring.
Doctors recommend you wash the affected area with soap and water as soon as it comes into contact with the plant and then cover the area.
Spraying with herbicide is an effective treatment to stop invasive plants from spreading.
Also going by the name of wolf's bane, devil's helmet and aconite, monkshood has been linked to sudden deaths throughout the last few centuries.
Its toxins in the plant, which boasts large leaves, can kill by slowing the heart-rate and triggering heart attacks.
It is absorbed through the skin, and is one of the country's most poisonous plants.
Poison ivy - infamously - causes a painful and itchy, blistery rash on your skin if you come into contact with it.
The good news is you’re unlikely to experience this nasty skin reaction because we don’t have poison ivy in the UK. It only grows in North America.
English ivy isn’t harmful, although you should still be careful when handling it if you have sensitive skin as its sap can be irritating.
Handling the parsnip plant can make your skin very sensitive to light leading to burning, blisters and a painful rash.
This is because the plant's sap contains chemicals called furoumarins, which cause skin inflammation.
Generally found in woodlands, the flowers can also grow in hedgerows and also go by the name of lords-and-ladies.
They are poker-shaped, surrounded by green leaf-like hood, and its red and orange berries pose danger.
They'll make your mouth swell, and throat close, if digested.
A common garden plant popular for its tall stem and, in the most common form, purple flowers, Foxglove plants pose risks.
Eating any part of the plant causes vomiting and diarrhoea and can even result in heart attacks.
The berries from deadly nightshade release a poison which paralyses nerve endings, the heart, blood vessels and muscles internally.
This will cause dilated pupils, and other symptoms include a sensitivity to light, blurred vision, confusion, convulsions and headaches.
Two berries are enough to kill a child, while ten to 20 will kill an adult.
Eating these can result in anything from dizziness, dry mouth and dilation of the pupils to irregular heart rhythm and death.
Despite not being native to the country, it can be found across the United Kingdom and - when eaten - causes sickness.
