All my Brazilians are sour/acid , that's what the market here wants .
Mike are you saying that your huge ones are really sweet ? The only sweet ones that I tried growing here were lingularis and the purple Hendricks , they don't do very well , not worth it , so they will be removed . Besides the quadrangularis and alata , the only other one that fruits almost yearround is the maliformis , to bad the last one is small but a keeper for my personal use . Have some maypop planted from south usa , see how these will do , never tried them , don't even know if they are sweet or acid.
