Charles and Millet, when you refer to Col de Dame, are you referring to Col de Dame Blanc (the white/yellow fig)? The USDA repository at Davis has one of their accessions labeled simply Col de Dame. That is Col de Dame Blanc. Mine has grown well and I've rooted a couple more cuttings to expand my planting. I also have Col de Dame Noir. It's still small but has been fast to root and a good grower. I got a couple of cuttings of Col de Dame Gris (supposedly with the earliest ripening fruit of the three) but they died so I will have to try again.
