Cold i occurs when temperatures drop during the night after a warm spell, particularly when vines are not fully dormant (in fall or late winter). The trunk usually is damaged, which weakens older plants and sometimes kills young vines. Although methods such as wraps and plastic sleeves may help protect the trunk against freeze injury, they are not always effective. The trunk's sensitivity to cold decreases with age.

The following cultivars are available (all A. deliciosa) and have been tested in the Pacific Northwest. All produce bright green-fleshed fruit.
