Zone 6b/7 summer temperatures mid 80s to high 80s. Occasionally mid 90s. Very sandy soil but I water them more frequently than other shrubs. Pollination is good.
Honey Bee is the healthiest looking. It has grown taller than Borealis but not as bushy. It actually has some new growth but most of it looks like it wants to go dormant. Both have produced fruit that was twice the size of Berry Blue.

Berry Blue planted 2012. It is losing some leaves but I expect it will be fine in the spring. It seems to be approaching dormancy faster than Honey Bee. (Editor's note: Russian varieties typically drop their leaves earlier than those with some Kuril Island or Japanese genetics, such as Borealis and Honey Bee).
