Registering a Daylily

The American Daylily Society is honored to be the official Registrar for the genus. Daylily Registration is the process of documenting the details about a specific cultivar. It is done by the Registrar under the guidelines developed and promulgated by the International Union of Biological Sciences, International Commission for the Nomenclature of Cultivated Plants as published by the International Society for Horticultural Science as the International Code of Nomenclature for Cultivated Plants, often referred to as the ICNCP or Cultivated Plant Code. These guidelines are set forth as horticultural regulations detailing the rules by which a plant can be registered. The Registrar does not have the right to waiver from these rules. Use the arrows below to flip through topics on daylily registration, or continue to the electronic registration process.
