Whats up JC, The only seedbank i use is greenhouse seeds and from experience they have something that is close to the original blueberry! They used to have the original but someone who worked there left and took the original genetics with them and setup there own seedbank, i can't for the life of me remember what the name of the seedbank is, but i will find out and as soon as i do i will post back the name.
But as i said i always use greenhouse seeds.
Take a look my brother.
Peace
