This IB seedling just opened yesterday, not quite enough buds but I am hopeful it will be fertile as I am trying to take it down into the SDBs using some SDB seedlings with decent bud count. Initially I wondered if I had reversed the parentage on this, but it is correct. Blueberry Tart rebloomed or probably more correctly repeat bloomed towards the end of the TB season here that year and I set a few pods. Its sibs are taller and of similar pattern, but none with similar form so far. A few more to open yet. Oh and I must confess the standards are probably open a bit more than they would be if someone hadn't been nosing around in there before getting a good shot.
