Geerlings cultivates and processes Calla tubers, while GSBG and Sande have Calla breeding programmes.
GSBG in California will continue its business until September 2018 to assure delivery of orders to its customers. Production of Callafornia Calla has started in the Netherlands, with the first supply expected by the end of 2018, when Dümmen Orange will take over the supply to GSBG customers.
Dümmen said: "This step underpins our firm belief in the importance of scale. A broad portfolio is the strategic response to the trend of consolidation amongst growers, driven by the growing influence of retail markets. In taking these steps, Dümmen Orange makes the Netherlands the undisputed center of Calla breeding in the world."
This addition also means a broader range of cut flowers and pot plants in the assortment of Dümmen Orange. In addition to Calla, Dümmen Orange also brings the other bulb and tuber crops from GSBG into its portfolio including Zantedeschia aethiopica, Scilla peruviana, Scented Begonia and Eucomis hybrids.
