Berg RoseS are proud of the way they grow their rose assortment. A total of 12 varieties of roses grow on an area of 16.5 hectares of greenhouse. The plants of the roses last a long time, averaging eight to ten years. After the flowers have been cut, they go into the cold store for a day at a temperature of about three degrees Celsius. Like a cold shower after a visit to the sauna, it strengthens the roses, so they can eventually stand longer in a vase. After the cold store, the flowers are sorted, through an automated process, according to bud size, stem length and quality.
