"Indian Magi" is less hardy at -30°F. While its fruit does not persist into winter, it tends to bloom profusely in alternate years. "Snowdrift" is rated to -30°F. The fruit tends to be somewhat persistent into winter, but the birds need a treat too. All are reasonably disease-resistant (including cedar apple rust) varieties, but there is no guarantee that they will always express that resistance.
