Conforming Names - The International Code of Botanical Nomenclature for Cultivated Plants (ICBNCP) issues guidelines for the proper naming of plants that result from intentional human activities such as hybridizing or selection of sports in the case of hostas. ICBNCP sets standards for such things as name lengths, words that are not acceptable and which words in the name are not capitalized.

The common format for a cultivar name has a single parenthesis at the beginning and end with words in the name generally capitalized such as 'Abiqua Drinking Gourd'. Certain words in a name are not capitalized such as 'Sum and Substance' or 'Night before Christmas'. When plants are registered with The American Hosta Society, the Registrar consults the ICBNCP guidelines before accepting a name. Non-registered plants are named anything the originator desires but they may need to be changed prior to registration.

Non-Conforming Names - The hostas listed below are generally "breeder" plants that were used in the background of hybridized plants but were never given a formal cultivar name and were not introduced into the nursery trade. We have placed the word "Seedling" in these names. Many others were given "temporary" names which were later changed to acceptable cultivar names by various Hostaphiles. These plants have quotation marks " at the beginning and end of the name.
