Deleeuw Flowerbulb Group B.V. is currently runned by two brothers named Rob and Hans Oudshoorn. It has always been a family company. The great-grandfather of the two brothers, mister Klaas Oudshoorn, was working as a grower of flowerbulbs in another company from 1900 till he past away in 1936. His knowledge was passed on to his son, Leen Oudshoorn, who started growing flowerbulbs since 1949. Twenty years later Leen started a company together with three other men. Among these men was his own son Klaas Oudshoorn and a close friend Floor Barnhoorn.

These companies were named Harry Deleeuw Company. One was located in the Netherlands and one in South africa. In 1986 the founders decided to separate the companies and the south african office was renamed to HADECO. The family Barnhoorn continued HADECO and has currently two brothers, Charles and Stuart, running the company.

Klaas Oudshoorn became the full owner of Harry Deleeuw Company in the netherlands. Business went well and other companies were taken over (Delta in 1975, K&M in 1996, Kapiteijn & Zonen in 1996, Broersen export in 2000 and Nieuwenhuis in 2004). This new group of companies was put under one name: Deleeuw Flowerbulb Group B.V.


Trust in bulb quality

Selection process

We only select flower bulbs from the very best growers on the basis of knowledge and practical experience of three generations of bulb-men. An internal quality control system contributes to the fact, that ultimately, only the best quality is found suitable for export. We store and prepare the flower bulbs ourselves, before shipment to professional growers or dealers all over the world.

Business is communication. The best business agreements are made when supplier and customer fully understand each other. In all our business contacts we attach great importance to good communications. For that reason, we have over the past decades built up a worldwide network of local agents or partners in most flower-growing areas.
