BTW, Adam, if the scions are from Mr Minh from Westminster, CA, then that maybe his Vietnamese Atemoya and not a Sugar Apple. And in which case, your first impression that it would be an atemoya would be correct.
Mr. Mihn is not from Westminster he is from Santa Ana 92704 and his atemoya is his own signature variety not the Vietnamese atemoya that's been floating around in Socal for 25 years.Here are some graft perform this year.

50% of all my grafts have hit this year but with mangos I'm 5 for 22. I have not had a take on a.reticulata,a.muricata or pouteria sapota.
