There is a(new?)Blueberry out called the Bluedrop.Besides the unique berry shape,a grower says it can fruit from June til frost.
The Lubera guy is the only one I've heard talk about it and he is a grower in the UK.
Does anyone know if it's in the states yet? Thanks,Brady

I'm including a link to videos.
