I've only been growing SHB for four years, so I don't have much have much of a track record at this point. I'm very pleased with a Legacy that I bought from Burnt Ridge in 2014, but it's still early days (I've had problems in years three and four with a South Moon and O'Neal, so I'm being cautiously optimistic). I'm in my third year with a Scintilla and Sweetcrisp, and both of those are doing reasonably well. Scintilla impressed me last year (good crop for its size and excellent flavor), but it was really thrown off by the weird December weather and then took a beating once winter did arrive. It's still managed to produce a modest crop this spring, but it looks rough. Sweetcrisp produced a very small crop last year, but this year it's looking much better. Finally, despite its really low chilling requirement, I've had very good luck with Sunshine Blue. I bought it in 2012, and it's reliably produced a good crop (for its size) since 2014.
