Well done!
Don’t know if that could be useful, but this year I have planted 4 different commercial “maximosch” interspecific hybrids: first in between my maxima plot, other in my moschat plot, 100meters apart. Name of these strains : Tetsukabuto, Iron Cup, Maukai, Shiatsu. All doing relatively good here. (related post here ). Very curious to see how these turn in later years… but I don’t have a clear project with these yet, more for fun.
