At a local botanical fair, I bought a guava, called crystal, I gave it to my wife to try, I am not much of a fan of eating guavas out of hand. anyway, she really liked it a lot, it so happens there is a Taiwan experimental station in the DR. they had 2 varieties, Crystal, and I think the other is called Celeste , both white crunchy types, both baseball or a bit larger sized fruit.
I bought one plant of each, but lost one, the other is hanging on, but still pretty small. anyway, guess what I am saying is, they are pretty good tasting. but guavas seem to be a magnet for pests around my place.
