Thank you Frank and Becky and Bill. Calvin, I'm pretty sure it's UCD, by way of Michael in Virginia.
Francisco, I have a mini orchard behind my house. I planted 6 or 7 feet apart and plan to keep 6-7 feet high. In this spot I have Bebera Preta, Pastilierre, CdD Blanc, Figo Preto, and Grise de St. Jean. Also 2 Ronde de Bordeaux, that I am espalliering on the wall. I'll have a LOT of cuttings, keeping these trees the size I want.
