That is not a Dasyblasta; it is a standard variety of Surinam cherry. Based on the dark coloration, it could be descended from a Zill Dark or other improved Surinam cherry, but it is certainly not a Dasyblasta Surinam cherry. Dasyblasta is a variety of
Eugenia uniflora, so its foliage looks identical to any other variety. But, one only has to remember the other name for the Dasyblasta variety, smooth pitanga, to know that the fruit is very different. Dasyblasta fruit is small, round, bright red, and smooth, not ribbed like other Surinam cherries.
Flying Fox Fruits' site has a photo that should give you an idea what a Dasyblasta actually looks like:
