How do you know it's a Bocking variety?
. . .
I went looking specifically for Bocking 4.
I read that the roots of Bocking 4 go down ten feet and the roots of Bocking 14 go down eight feet. I wanted plants that go down as deep as possible because they were going to be planted along the sides of a creek and they were going to serve as erosion control, like living pilings that hold the ground in place.
The supplier I found said that he only ever had Bocking 4 on his property, nothing else.
Perhaps he lied.
Or he was being honest, but his supplier lied to him.
Or his supplier was being honest, but that supplier's supplier lied.
etc. etc.
Hopefully, everybody along the supply chain was honest.
Otherwise, there would be no way to confirm the genealogy of the plants all the way back to Bocking, England where the variety was developed.
All we can do is trust the people we deal with.
