Check out this Bebbs. It's in its 3rd summer and looks great. Acorn from OakSeeds.
I have a couple Bebbs from different sources and they all are out growing most other varieties that I have.
Oaks are the long game planting a tree that could still be alive in 500 years gives a sense of accomplishment. My apple trees in my area are not likely to be very long lived my pears maybe a 100 years maybe a bit more with luck but the oaks may be there a long time.
Grabbed a couple pics today of Concordia bareroots planted this spring. The first one looks very happy. The second one seems a bit stressed as some insect must be nibbling on the leaf edges...the leaves were much larger 2 months ago
Nonetheless I expect it will be ok
