Well,for one example This fig is a very productive cultivar in Spain,and it is today grown Comercially for the fruit market,by most orchard owners there.
Would you believe that the Deparetament of agric.,her and the UCD California ,and all other fruit Programs Texas,Louisiana,they all knew from the start the Col De Dame is a good grower and has best Flavor,but for a small technicality,they rendered it non desirable for Comercial production in The USA.
The Technicality is that the fruits of a Fig tree are harvested for more than one purposse:Fresh fruits,Dry fruits,Fruits compot,syroop,or fig Jam ,and also at the end,Fig paste.
All Col de Dame cultivars are good for all the above,but.
The Deep red interior of the fruit was not acceptable for fig paste because of the dark pigment in the fruit that will color the paste.
So for this unimportant reason,they rendered it useless,and went on reaserching for hybrids,with light color interior,that are totally inferior in everything Taste Flavor ,resistance to splitting and souring,etc.
They trew the Col de Dame in the collection,and never used it,again,or encourage spreading it in the USA.
What a pity.
If it is Comercial in Spain it can be comercial here in California,Texas,and Louisiana for sure.
The Plant is resistent to rain and souring,and as a mater of fact I found it cold resistent too.
My plant is in ground and it was the last 3 winters and is doing just fine with a little help from me ,of course.
I mean a little mulch around the base,a tarp over in the coldest Part of winter,it is not so hard to do!.
The results will surprise you.
