aurora is partially self fertile. its one of the few cultivars that is but of course will produce bigger berries and more of them with another early pollinator. i like the earler producing honeyberries as they are my 1st fruit in the summer and get done as the strawberries start ripening. i think thats why the birds dont touch them. they ripen when there isnt any native berries to be had so the birds dont know what they are.
