I bought my two trees at Excalibur, and if I'm not mistaken, they're seedlings. I've never tasted a non-acidic one, but non-acidic soursop sounds like an oxymoron. My wife says a non-acidic guanabana is called a cherimoya! Of course, annona muricata is not annona cherimola, and the flavor, though similar, is different. Texture is definitely different.
