Well as far taste I'm not very experienced and have only tried a few, but of the ones I have tried the mory of my first WS (Redlands) was the best ever. Julian gave me a couple about a year ago and that taste has not been matched in my mind yet. All summer I have been eating the ones from the Fruit and Spice Park (ironically except from the Redland tree they have there) and they are good but not better than the redland's I ate last year. The one's Julian gave me were from his own tree. I have a redland grafted from that tree now. This summer Julian gave me a Campbell (his favorite) to try. It was very good, but not as good as last years Redlands. Satya recommended the Younghans which I have yet to try but want to.
As far as the Yellow Sapote, I never knew about them until this summer. Like I said before, i missed Satya's offer because I was away from the forum for a blink. The seeds I got from Raul do seem to be growing strong so I am excited about that.
I don't have a lot of space but am growing as much as I can of fruits that I like. I have 5 dwarfish - low vigor mango trees (one is multi grafted), Bananas, 2 papayas, Soursop, Red sugar apple, Multi-grafted atemoya (Lisa & African Pride), Makok Sapodilla, several pineapples, Rollinia, Mai1 Jackfruit, dragonfruit. Some are in the ground some in pots. I'm being selective as to what I put in the ground because of space which is what caught my attention to the yellow sapote dwarfing WS. That is ideal for me. My WS are in pots but I am going to put one in the ground soon.
Thanks for all the sharing and great information. This forum has been the best!
