The cultivation area for Longiflorums is approximately 150 hectares. Most of that, 110 hectares, is occupied by White Heaven®. The hectares are within 111 licences.
Six Dutch growers, which together have 104 licences, have started a partnership (The Longiflorum cooperative) in order to invest with breeder Mak Breeding in promotion, improvement and continuity. After all, the success of the most famous longiflorum, White Heaven®, should have a sequel.
Contact details of the participants can be found under the Growers.
