Alternative plants

Invasive non-native plants have sometimes been used in the past for difficult areas of your garden - a particularly exposed patch, for example, or where a bare wall needs to be covered quickly. 

The Plant Alert team at Coventry University have developed a list of over 160 plant species that do the same, or similar, 'jobs' as invasive plants and can be used in their place. This list is an update on a previous list developed by the RHS and Plantlife. You can download a copy of the booklet, or view the list below.

Remember, whichever plants you choose, it's really important to prevent them from spreading beyond your garden, pond or aquarium. Read our Be Plant Wise guidance for simple tips on how to do this.
