International Lists of Plants Names Published

Thomas Rainer feels we must move beyond trend toward a greater appreciation of plants, a re-wilding and a building of connection

The new editions (2021-2025) of the List of Names of woody plants and the List of Names of perennials contain more than 17,000 new names.

They are preferred names, synonyms and commercial names of almost 45,000 woody plants and 30,000 perennials, and they are the standardized names of the commercial range of nursery stock in Europe and largely the United States.

Most important changes

• Addition of more than 17,000 new names (8,200 woody plants and 8,800 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 4,000 cultivars.

Under the auspice 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 and legal correctness and practical workability.

Composed by Naktuinbouw

Since 2014, Naktuinbouw takes care of the registration of names of arboriculture crops. We work closely with other registering and coding parties, in particular Varb and Floricode. The new names are mainly notified by growers, members of ENA and ISU and via the inspection system of Naktuinbouw.
