With hundreds of different daffodils thought to be found in the UK, we’re calling on you to log where daffodils are blooming in your area. We’ll ask some basic information such as colour, type and height. RHS scientists will use this information to help understand environmental influences on daffodils, buyer preferences and spread.

We’re also calling on you to join the search for three daffodils that are either at risk or thought to be extinct in the UK. Locating these daffodils will help us aid their survival, better understand our gardening heritage, and even enable preservation of genetic material that could be valuable for future breeding of daffodils in the face of a changing climate.

Dr Kálmán Könyves, Principal Scientist in RHS Science’s Cultivated Plant Diversity team and expert in classifying and recording daffodils, explains why we’re asking you to log when and where you see daffodils in flower.

“Daffodils have come to mark the arrival of spring and are celebrated for their welcome burst of colour in gardens, parks and roadsides.

“But there’s more to this ubiquitous yellow flower than meets the eye, with 31,000 known varieties available in green, pink and red. Understanding where they can be found will help us in preserving this diversity for the future.�

Daffodil location data submitted will be anonymised to a two-mile radius (town scale) and information stored within the system for comparative purposes across years by RHS scientists. Please see the RHS Privacy Policy for more information on your rights under the Data Protection Legislation.

** Reporting of rare daffodils

Your email address and imagery submitted to the RHS via the Daffodil Diaries email address will be safely stored for the purpose of contacting you to confirm identification of daffodils believed to be one of three endangered cultivars. Please do not include any other personal data on the form. All information will be deleted after 30 August 2025.
