There are low chill blueberries I know but when it comes to sub tropical and tropical climates, even some of these can be recalcitrant fruiters. I have aquired seeds of the maidera blueberry and am going to have a go fruiting them. They have been used in hybridizing projects for commercial blueberry cultivars. They are supposedly almost evergreen and frost tender hopefully translating to no chill. they can also be pruned to one trunk. If i can germinate them I will give a few updates on how they are going.
