Enkhuizen/De Lier, the Netherlands May 20, 2026 – Dümmen Orange and Syngenta Flowers, two global players in ornamental breeding and propagation, have signed an agreement to establish a strategic joint venture. This partnership represents an important step forward for both organizations as they work together to better serve growers around the world. Both boards of directors have formally approved the deal, and completion of closing is subject to any necessary regulatory approvals.

The new company will combine deep industry and operational experience with a strong entrepreneurial mindset. Dümmen Orange and Syngenta Flowers plan to unite their strengths to build a more resilient and competitive enterprise. The joint venture will bring together both companies’ complementary portfolios, combining Dümmen Orange’s expertise in cut flowers and Syngenta Flowers’ leadership in seed varieties, along with annual, perennial and potted plant portfolios that both companies have built over decades. Advanced R&D capabilities, optimized production processes, and expanded commercial networks will be integrated to improve efficiency and better serve customer needs.


 

"Dümmen Orange and Syngenta Flowers are companies with a strong track record and legacy throughout the history of flower breeding,” says Mark Schermer, Global Head of Syngenta Flowers. “This combination brings the scale in breeding and production needed to serve customers across the globe, delivering the proven technologies and quality that growers depend on."

Customers will continue to work with their current contacts or supply arrangements, with enriched product offerings and more streamlined logistics to follow in the near future.
