That may depend on how "domesticated" the date is, although I suppose your statement could be in strict conformance with the Law of Identity.

I'm seriously considering doing some grafting myself this year. The place I go has probably 1000+ trees spread out over a couple hundred acres. There is a huge range of variation in terms of flavor. But my favorite ones for making cider are the pips (small, when fullsize, maybe the size of an oblong plumb). They make by far the best cider.
