It’s that time of year for gardening, but certain plants are so invasive that it’s actually illegal to put them in the ground. Plants, mainly non-native, are considered invasive under the Weeds Act 1959.

An invasive plant is any plant that grows where it is not wanted and does so in a way that makes it difficult to control. They don’t necessarily have to be weeds, and invasive plants aren’t always unattractive.




This means that you won’t find their seeds in the average home base, but they will still end up in our world. A very well-known example is , which infiltrates gardens in the United Kingdom every year.

However, there are others that are less known but are still illegally invasive. An example of this is Green alkanet, also known as Pentaglottis sempervirens.

Green alkanet is an invasive perennial common in shady and moist areas. Although grown in gardens for its attractive blue forget-me-not flowers, the plant can ‘quickly become a weed’ under the right conditions.

It is capable of self-seeding, leading to the growth of new plants close to the parent plant. In addition, it can be spread over long distances through animal fur or clothing. It has long, hairy stems, bushy leaves and blue flowers with a white center that open from a pink bud.

Allowing a non-native invasive species listed below to spread into the wild is a criminal offense, carrying heavy fines, the Express reports.
