Common plants you should NEVER grow in your garden
Green alkanet can soon take over your garden. As well as being popular with pollinators that spread the plant to different parts of the garden, it also produces seeds, which can be blown or transported to new locations on clothing or animal fur.
Enjoying the plant in your garden is quite easy, but you must control its spread. To do this, deadhead the plant before it sets seed and remove seedlings from unwanted locations. A layer of mulch will also stop any seeds from making their way into the soil.
The rhododendron bush is beautiful and dramatic, offering up spectacular displays of purple, white, pink and even orange flowers. Also known as azaleas, this woodland shrub likes to be planted in dappled shade
Sadly, this non-native species is proving detrimental to native plants. Its dense thickets create huge areas of shade, stopping other plants from thriving. In fact, once it has invaded a garden, few other plants can survive.
If you have a bush growing in your garden and want to remove it, then you can do so yourself by either pulling it out of the ground (if it's small) or digging up its roots.
Also known as lords-and-ladies, the cuckoo-pint plant is native to most parts of Europe, as well as some countries in northern Africa. As a wildflower, the plant isn't often found in gardens.
So, why is this unusual wildflower problematic? Well, the plant self-seeds, which means it spreads quickly and can soon get out of control.
