Gardening Without Harmful Invasives is supported by Defra, Natural Scotland and the Esmee Fairbairn Foundation. It aims to help gardeners make informed choices about the plants they buy.
Plantlife invasives officer Sophie Thomas said: "Often people aren't aware that their choices over which plants to grow in their gardens can make a vital difference to protecting the natural environment. The good news is that if we all do our bit, then the threat from these problem plants to our wild plants and animals will be much reduced.
"There are hundreds of beautiful plants that can be used in place of invasives and our booklets highlight some stunning examples."
Defra estimated that around 60 per cent of all problem plants damaging natural habitats originate in gardens. It hopes that by funding schemes like the guide, it can help limit the amount it spends on removing invasives from the wild.
RHS chief scientist John David added: "While only a tiny per centage of our garden plants cause problems in natural habitats, invasive plants are an increasing problem with real impacts on our natural environment and on property owners affected by them."
