Coloured carrots may seem modern, but they were already available before the 17th century. When the Oranje (Orange) family ruled the Netherlands in 1684, the well-known ‘orange madness’ started in the Netherlands. In addition to orange palaces, orange marmalade, orange liqueur and orange trees, the carrots also had to change colour. The carrot farmers in the Netherlands were allowed to only grow orange carrots in honour to the family. Fortunately, nowadays other colorful carrots are becoming more popular.
