Well Frank :Not all wholesaler use this ,fast way to get rich,but ,some do,and that is why we have examples like the above poster,growing a Black Mission,that is something else.
Why I know it is done?.
Well before I knew better,I bought 2 figs from Home Depot,a Celeste and a Brown Turkey.
The Celeste was good but it was a Hybrid.
When I posted leaves of my figs ,all responders told me that the fruits look like Celeste But the leaves do not.
I show leaves ,in more than one pix and taken from close to be ID,and all other people that ID,showed me their Celeste Leaves and they were different.
The Brown Turkey,was looking somewhat Like English Brown T,but with smaller fruits that were ,yellow inside ,unlike English B T,and also the taste was insipid.
So That one was in fact an English BT Hybrid.
Then I got a Celeste from Lowes,and made fruits ,twice as large as Celeste with open eye,but they had Celeste look,so that one was another Celeste Hybrid.
Then I got a Brown T,,and a Celeste from Miller Nursery and they made,very small fruits,and use to drop them easy without good reason,WHY: because they were hybrids made from seeds too.
This large nurseries have no control over their stock,and so they can't be held responsible,Yet they should,because it is frustrating for the gardener.
Regulations should be in place as to,Only trees grown on the premisses should be propagated and sold,to gardener,so the nursery will be able to have accuracy when They tag a cultivar.
Without those regulation,gardeners will always have surprises like the above.
