Next to the Southmoon plant I have a Pink Lemonade blueberry in a similar pot, but Pink Lemonade produces significantly less. I am not sure it is worth growing in my conditions. In the picture below is a comparison of a harvest on the same day. I do not see many berries forming on Pink Lemonade either.
I have two more cultivars that just started to produce this year. These are still small plants, but I can already see that their berries are very different. Climax (left) and Krewer (right) are shown in the picture below. Krewer fruits are very large, probably the largest blueberry fruits I have ever had.
