From the reviews I’ve seem, AK Beanbrain and Jordan of the isles blueberry are your best bets to find a real blueberry smells and flavors. I bought a clone of a DJ shorts Blueberry that is very distinctly blueberry, no idea what vintage seeds it was found in.
I haven’t grown them yet, but I got a pack of these. He has a variety in his blueberry line too (blue crush)
