The extension agencies often recommend things that are quite old, and rarely recommend anything newer, regardless of how great they seem to be. Since they are guiding commercial growers, they err on the side of caution and only recommend varieties with a long, proven track record. Those highbush varieties are really outdated and mostly not that good here unless you’re in a cooler location, with the exception of Blueray. It’s the only northern highbush that’s done really well for the Kelly brothers in Castalian Springs. They operate the largest blueberry farm in TN. Their late season varieties are still mostly Tifblue and Climax for the u-pick customers. Decades old and still extremely productive.
