White Texas everbearing is not a sport of Celeste that grew in a Celeste orchard in Texas.
That is a made up story.
White Texas ev.is the same tree as Kadota,(Dotato),in Italy,and ,it does produce spongy fruits ,in addition to some normal ripe fruits just like all other ,Kadota type figs.
It can be good only in certain climates,and especially where the fig wasp is present.
Those spongy dry cardboard tasting fruits,in my opinion,were Female fruits that needed pollination,and it did not have a way to get pollinated,so because the tree is persistent,it keep the fruits on branch any way,till someone removes it and find out it is dry inside,and inedible.
Yet it does have more normal edible ripe fruits than dry inedible.
It happened to me with:
White Texas everbearing,Kadota, Dotato,and white Russion,figs that in my opinion are all one cultivar.
Also according to Mountain man,in Texas,Banana fig is also Kadota but I never grew one once I figure it out Kadota type is not the cultivar for my climate.
