I’m getting blackberries for the past 2 weeks.
First was Columbia Star. They are very big and I like that the vines are thornless. I’m not crazy about the flavor, but if they are dead-ripe, they start to be sweeter and more complex.
Now I’m getting Ebony King. They are round, compared to the oblong Columbia Star, and not nearly as big. But the flavor is much more complex and rich. The vines are thorny and vigorous. They are sold as thornless or reduced thorns, but tell that to my scratched arms.
Now the Prime Ark Freedom have started. They are big juicy berries. The berry size is similar now to the Columbia Star. I think they taste better than Columbia Star, but maybe not as good as Ebony King. Of course, the Prime Ark Freedom is nice because of being thornless and primocane bearing. The current crop on those is floricane, the primocanes are just starting to bloom.
I also have new plants (one year) of Arapaho and Triple Crown. Those have blooming floricanes now.
I am in Zone 8a in Southwest Washington State. That may affect flavor and yield dates.
