A nursery in Belgium offered, some years ago, among several different fig varieties, one called "brune de Turquie", French translation of the in English "brown Turkey".
One of his German customers bought this cultivar then, very pleased with the varietyÂs results, renamed it and apparently registered the new denomination.
But even if you change the name, the substance remains the same, even with a registered name the Violetta is nothing else than an "English" brown turkey.
Just to let you know the rest of the story, the Belgian nursery, having seen the commercial success of a simple action of redenomination, decided to do the same: "brune de Turquie" became "grosse brune dÂEnghien". Having done that, they did not change the photo in the web catalogue (I still have the page showing the brune de Turquie). This cultivar has disappeared from those pages, and has been replaced now by the "grosse brune dÂEnghien", qualified as to be a very special selection of the nursery and represented by the same old photo.
This information comes from a very, very reliable source, someone well known, in Europe and in the world, for his love for the ficus carica.
