An overview of open days at several participants

Still a bit of FlowerTrials this year

Week 24 is normally the week in which breeders physically present their varieties at various locations in the Netherlands and Germany during the FlowerTrials. Despite the fact that the physical displays cannot yet take place under the FlowerTrials flag, there are still many breeders who open their doors by appointment. Below is an overview of the breeders (and normally FlowerTrials participants) who can be visited next week by appointment (!).

P.S. The FlowerTrials team itself is not sitting still either: next week participants and highlights will be presented during the digital initiative 'Studio FlowerTrials'.
