Naktuinbouw Select Plant

If your propagating material complies with higher quality or health standards, it can be considered eligible for certain certificates. In cooperation with the arboricultural sector, Naktuinbouw has developed several quality-plus systems that enable growers to demonstrate the added value or superior quality of their crops. Naktuinbouw Select Plant is one of these systems.

About the inspection

Under the Naktuinbouw Select Plant system you will be granted certification for tested lots of propagating material that offer extra quality. The Naktuinbouw Select Plant certificate confirms the higher quality level of your products. This can apply to an entire lot, or in other cases to individual plants. There are currently multiple varieties of floricultural crops that are eligible to apply for Naktuinbouw Select Plant certification (please find detailed information here):

  • Hosta
    See the list of registered companies that can provide a Lot Declaration Hosta 
  • Avenue and Ornamental trees​
    See the list of registered companies participating in Select Plant Avenue and Ornamental trees


The standards and conditions that Naktuinbouw Select Plant participants must comply with are described in the Certificeringsreglement Select Plant Alstroemeria and Certificeringsreglement Select Plant Freesia. The more stringent standards relate to the quality and health of the propagating material. Laboratory tests are often required to establish if all the criteria have been complied with. When certified material is assessed, particular attention is paid to varietal trueness, varietal purity, origin, health (free of viruses, fungi, bacteria or nematodes) and quality. 


You may only trade propagating material or perform tissue culture activities within the framework of the Naktuinbouw Select Plant quality-plus system if your company is a registered participant and if the company meets the standards and conditions stated in the regulations.


The Naktuinbouw board establishes our inspection fees each year. The fees are subsequently approved by the Minister of Agriculture, Nature and Food Quality. The costs are charged based on the cost-maker cost-bearer principle. The fees for inspection can be found here Rates/fees.
