Finally I was able to get a small plant of this hybrid from Eisenhut in Switzerland. He got it initially from Mr. Vosss in Germany who is growing his in the garden. Mr. Voss got his from the USDA as US-852, so I was told. Hopefully this is the true one
.
Leaves are typical citrandarin and I'm very keen on having fruits in order to test this rootstock. Was anyone else able to obtain the plant or seedlings?
