Welcome to Austin,
I grow some of these names and here's my experience with them so far.
Black Madeira from UCD growing in my yard totally unprotected and hardly growing in its third leaf. It is still about a foot tall. It could have something to do with the soil. It Produced a few delicious figs in its first season but the wait so far in my opinion is not justified.
I prefer the faster growing Violette de Sollies with its large delicious figs and upright growth habit. It will make a nice tree in your yard.
It has other names, Bourjassotte noire, Barnissote noire, Parisienne.
Col de Dame Gris is growing like a shrub in my yard and not very productive when compared to the Col de Dame White from UCD
The flavor is very close when comparing Col de Dame Blanc Noir or Gris with each other. Unfortunately the winter freezes will trim the Col de Dame Blanc each year.
The only one of the three growing slowly like a tree (not a shrub) is the Col de Dame Noire but again has not been productive in its second year.
I have Nero 600m in pot but still too young to judge. This one has been hard to root and lost two batches before I finally had a specimen.
Panache in pot and after three years is becoming root bound and did not produce a single fig for me.
Peters honey died twice on me and I stopped growing it as I have another honey type variety that does the job for me. It is the Deana fig. It has been super productive for me here in Austin.
Strawberry verte, is too general for me. There are many varieties that fit this description. I know Sucre Verte which is a French cultivar in pot. It is a super fast grower but has not produced a single fig so far. My green Ischia is wonderful.
When it comes to fast growth, Preto will leave the Black Madeira in the dust. My Preto came from a member of this forum and in one year it grew over three foot long.
My Black Madeira grew one foot in three years.
Since all Col de Dame figs are very close in taste, so far I prefer the UCD Col de Dame (Blanc) for productivity over the Col de Dame Blanc(Baud) and others.
Of the three, for best looking tree so far, Col de Dame Noir is the winner. It is not fair to judge a tree after two or three years, but this is just an observation.
Panache would be a great specimen in my yard, but still waiting for those figs. My Panache was purchased from a reputable nursery online and there's no doubt as to its authenticity.
I was so impressed with those panache figs sold at HEB that I had to get a tree.
By the way the store bought panache fruit tastes awfully close to any Col de Dame.
If I had room for only 6 trees in the ground my list might look like the following and not in order of preference:
Violette de Sollies (dark) great looking tree with large tasty dark figs that form a drop of honey when ripe.
You could see my tree here: http://figs4funforum.websitetoolbox.com/post/the-perfect-dark-fig-violette-de-sollies-7544044?pid=1288299389
Fracazanno Nero (purplish black fruit that is simply amazing)
Preto or another version of Black Madeira for faster growth.
Atreano produces large green super delicious figs that the birds will hopefully miss.
Jaune de Gascogne a most gorgeous tree.
Panache. I'm still hoping that my panache will eventually produce those wonderful looking figs. They should have time to ripen over the fall in TX.
