This question gets asked a lot on RIU but it always ends the same. The blueberry of yesteryear is "gone" so we are left with many separate breeder's work with those old beans. From what I've seen in person and via forum/internet is that the crinkle leaf mutant pheno of blueberry that was colored nicely, tasted like berry jam and was really potent has been bred out of most breeders lines. Doesn't mean there ain't fire blueberry but just not likely to find those mutants gems anymore.
I still read any thread pertaining to blueberry and love finding out or seeing new examples of blueberry and her crosses.
That being said I currently have a seedsman's blueberry (feminized) and an HSO sour blueberry (feminized) in flower (5 days). The seedsman definitely resembles my old dutch passion blueberry from '02, it has fat fingered leaf blades, grows slow, side branches don't want to spread out and doesn't like being topped.
