Flavor breaks down and is unpalatable after one month in refrigerated storage.
Uniformly shaped, large fruit evenly distributed throughout tree canopy. Moderately vigorous, somewhat weeping growth habit, some tendency for tip bearing. Resistant to winter cold injury and expected to be well adapted in the North Central U.S., Southern Canada, and similar climates. After initial observations, The Swedish University of Agricultural Sciences, Balsgard, has concluded that Co-op 12 is well adapted under Swedish conditions, and recommends the cultivar for home grower use.
