New editions of the Lists of Names of woody plants and perennials


The new editions (2016-2020) of the List of Names of woody plants and the List of Names of perennials  contain more than 12,000 new names. 


They are preferred names, synonyms and commercial names of almost 45,000 woody plants and 24,000  perennials, and they are the official names of the commercial range of nursery stock in Europe and largely  the United States.


Most important changes:

  • Addition of more than 12,000 new names (8,500 woody plants and 3,500 perennials).

  • Various taxonomic changes in names after consultation with trade and industry.

  • The status of protection by Plant Breeders’ rights has been added to around 7,000 cultivars.


Under the auspices of the ENA and ISU

The list of names of woody crops is supervised by the European Nursery stock Association (ENA), and that of perennials by the Internationale Stauden Union (ISU). This makes them the international guiding lists in the nursery industry for determining the correct spelling and the preferred names of deciduous trees, conifers, fruit and perennials. The cooperation with these parties ensures a good balance of scientific/legal correctness and practical workability.


Composed by Naktuinbouw

In October 2014 Naktuinbouw took over the registration of varieties of nursery stock from PPO (Applied Plant Research). This move also made Naktuinbouw responsible for issuing the lists of names. These editions could be realised partly with sector funds made available by the former Dutch Product Board for Horticulture.
