In the kind of the blueberry, the basics of the preference choose the kind which suited the climate. Then, it becomes easy for the one which planted equal to or more than two kinds to consist of flower more actually and a lot of blueberries are consequently produced in the different kind of the same system. (True size sometimes becomes small when fruit is too much stuck.)
The blueberry of Hightbusch type is the optimal for the district of the climate where a lot of snows pile up. Northern Hightbusch is suitable more in Hightbusch type.
The blueberry of Rabbiteye type is the optimal for the district of the climate where snow doesn't pile up too much.
As for the characteristic, that the tree compared with Hightbusch type becomes big is early.
Southern Hightbusch type, too, is suitable for the other. But, it isn't suitable too much at Kyushu and Shikoku.
