RHS Threatened Plant of the Year

Plant Heritage, the plant conservation charity, celebrates its 45th year with a special display at RHS Hampton Court where the finalists for the Threatened Plant of the Year competition are displayed and the winner was announced

About the competition

Plants can be lost to pests and diseases, climate change, changes in plant trade or simply by falling out of fashion. Plant Heritage works to protect rare and endangered plants through National Collections, Plant Guardians and Plant Exchange, as well as the Threatened Plant Programme.

Each year gardeners are asked to nominate unusual, rare or special cultivars that are not currently available commercially and may be in danger of disappearing altogether. The finalists are judged and a winner announced at RHS Hampton Court.
