The seedlings did not like being outside, died when I went to Italy and Hawaii for vacation.
I did get a large RubyxSupreme fruit from a friend who has a large/tall tree today. It smells very fragrant, flesh is very red and looks good. Taste wise, it was definitely better than the Red Malaysian guava, but not better than the Carmine/Sylvia or the Indonesian Seedless guava. To me the taste of RubyxSupreme was milder than the two I mentioned but it is still very good so I will try to graft it to my tree next year. I measured the brix and it was 12. I'll post a few photos of the fruit later.
