Garden Escapers!

Working with gardeners to prevent 'future invaders'

We need you! Help us identify and prevent 'future invaders'

We're teaming up with gardeners to identify and prevent 'future invaders'. Focusing on six locations (see map), we'll be looking at which ornamental plants are spreading in gardens and those which can be found outside gardens (like those found in neighbouring protected areas).

What are invasive species?

Globally and here in Wales, ornamental garden plants spreading from gardens are one of the main sources of invasive species which affect our native wildlife. The majority of ornamental plants we find in in our gardens are non-native but are not causing problems. However, a small number we label as invasive species because they have escaped from gardens and impact the environment, economy, our health and the way we live. Invasive species have been recognised globally as one of the top five threats to nature and could become an increasing problem because of the climate crisis.

Examples of known invasive species include Japanese knotweed (Reynoutria japonica), three-cornered garlic (Allium triquetrum), Montbretia (Crocosmia × crocosmiiflora) and Spanish bluebell (Hyacinthoides hispanica). Species which are not currently invasive but have potential to be so include examples such as chocolate vine (Akebia quinata), Himalayan honeysuckle (Leycesteria formosa), Japanese anemone (Anemone × hybrida).
