Nothing yet, our cherries just started flowering this past week. Same for the haskaps, and the plums should be flowering in the next week or two. Our patch of ramps has grown again, which is nice.
I've heard that some cultivars are very sweet with almost no tartness to them. I think 'Indigo Treat' and 'Aurora' varieties are two of the higher sugar/lower acid, and I personally think they're sweeter than blueberries. But you can also harvest them early and get a real blast of yummy tartness instead
Those sound yummy! I really enjoy a high-quality, sweet blueberry, so I would probably enjoy those. I won't be growing them here, but anyone reading this who has the climate for them, give them a try!
