garrington choke cherries

garrington choke cherries, a selection with larger fruit, vigorous growth and large loosely spaced clusters. in the fall they're alright to eat off the tree, the later they go in the season the higher the brix, and despite the name chokecherries when ripe can be mild with low astringency, I suspect the name is related to their high tannin content. I've grafted out a few cultivars, garrington among them but I think it may not be a cultivar - the pfra in Canada grew seedlings and distributed them, so I've found shelterbelt rows of garrington where each tree had slightly different fruit, even different shape like the oxheart chokecherry seed we collected last year with pointed football shape seeds, which are normal close to round, slightly oblong
