Regarding bud.9 interstems - Cummins Nursery in NY is beginning to sell
interstems of G.11 on MM.111 of certain varieties for spring 2011, might
be similar to what you're looking for. At least they'll be somewhat
smaller, productive, and precocious. They told me to expect between
10-12', but this of course varies with cultivar, etc. . . . Not quite
sure what spacing I'll be using with these yet . . .
