Yes! Good eyes! They are starting to get bigger. This is the summer crop, the primocanes will produce a fall crop too.
You're batting a 1000! Some say they are tart, but if you let them hang, they are sweet and tart, and one plant produced over a hundred berries. Extremely prolific, I'm sure they will make a great jam.
The pink ones are H. Red I think? It was supposed to be a Hin. Yellow, it's the red I'm pretty sure.
Yes, a few blackberries ripe, most are still not ripe. Boyson is the reddish ones, and Columbia Star, and New Berry, and also Natchez (a few hundred still ripening). Triple Crown, Chester, Navaho, Lochness, Marion, Siskiyou and Burbank White are still immature, most at the red stage. Darrow, and Nettleton's Creamy White have no berries this year. Tayberries, and Wyeberries are about done.
