Since 2017, Boskoop’s Royal Horticultural Society (KVBC) has been judging garden roses and awarding them with the Certificate of Excellence. Excellence Roses is a Dutch/Belgium mark of quality and to qualify for it a rose must combine exceptional beauty with excellent health and reliability. Excellence Roses are also committed to sustainability as they can be grown without using any crop protection products.
Each potential Excellence Rose is on trial for three years with rose trial gardens situated in Winschoten (rosarium Winschoten), Boskoop (Rosarium Boskoop), Merksplas, Belgium (show garden De Kleine Boerderij), Mechelen, Belgium (Vrijbroekpark and Lottum (Rozenhof Lottum).
Receiving recognition for excellent rose breeding was Jan Spek Rozen for the soft pink floribunda rosa ‘Sweet Romanza’.
Belgian rose breeder Viva International received Excellence certificates for their floribunda roses ‘Midsummer Snow’, and ‘Princesse Stéphanie Grande-Duchesse héritière. The latter is a creation of rose breeder Martin Vissers. The rose has rich apricot buds that open to chalice-shaped blooms.

For the upcoming season, 27 new garden roses from 8 breeders will be planted for trialing in the Netherlands and Belgium.
