A kind neighbor gave us two baby blackberry plants (3" tall max) back in the fall of 2014. He had ordered them from somewhere and had intended to plant them, but never got around to it. They didn't fruit at all in the summer of 2015. In Jan/ Feb of 2016, I pruned back what I thought were the older canes (but was just guessing as there had been no fruit in 2015) and we had a small amount of berries last summer. I did even more aggressive pruning of what I thought were the older canes. I had the idea to mark the ones remaining before the new growth began this spring- hoping that'll make the pruning a bit easier next winter.
My main question is if anyone knows what variety they might be. The fruit has been decent; not amazing, but it's been a very rare blackberry that I've tasted and adored. I spaced them way too closely- maybe 2' apart. They are getting lots of flower buds and I noticed the pretty magenta petals poking out. If I recall, they do fade to white so I googled and saw here http://homeguides.sfgate.com/thornless-blackberry-plants-pink-flowers-63807.html that they might be Black Satin or Thornless Evergreen. Anyone growing those or recognize the buds?
I'm of course getting suckers/ volunteers which I'm happy to share with anyone locally!
