My first attempt with these was in 2010 and while the seeds did sprout, conditions here were not to the likeing of these vines and so success was completely avoided. However I tried again this passed season, with greater luck, and behold the fruits of that labor! Conditions were still not optimal, and I am quite sure they weren't fully ripe. The flavor of these is rumored to be exquisite, and these were a bit flat. But they are small and round, perfect for two.
As to the age of this particular variety, I have no firm information at this time. Seed catalogs aer often.. createive.. in what they say about a variety to entice buyers, so I don't place a lot of stock in what they say. This coming year i'm looking at this and also the petit gris de rennes, which is also an 'old' variety.
