Jon,
The Panache has a fruit that is appropriately striped, in fact, part of the trunk is variegated, so I'm certain of it.
The VdB had a little black breba on it back in March (which I pinched off), and has small spikey leaves.
The leaves on the other two are very similar, if not identical. I don't have any form of digital camera or I'd post pictures.
One has a four fruit breba crop (for months now), the other has two fruits that are recently formed near new growth. I figure they are either Kadota or Conadria.
Obviously, I can't know for sure where they were switched or mislabeled, but I didn't get the impression that the nursery had many SOFT orders, especially of other fig trees to even switch with.
When they were brought out to me at the nursery the four were tied together, but separate from the peaches and cherries I ordered.
They were nice sized trees, well worth the money, but I don't know about ordering from them again, I'm wary. Given the size of their operation I can see getting a tree mislabeled now and then, but two of four is not very good.
