The RHS is the International Cultivar Registration Authority for dahlias. If you've bred a new cultivar, you can register it with us.
The RHS maintains a list of cultivar names used in the genus, helping to maintain stability in cultivated plant naming which benefits breeders and buyers alike. Additionally, by registering, your cultivar will be eligible to receive RHS awards.
Registering your cultivar online is incredibly easy and takes less than 10 minutes. Alternatively, you can also register your cultivar by post.
The dahlia registrar will get back to you to let you know if your registration has been successful. If you have any queries, please email the registrar: [email protected]
