Just a botanical (?) thought: Winter Berries represent a food source for the wintering birds of your area. The flowers bloom in late summer & the berries develop close to the beginning of fall & last well into the late fall early winter. I have several berry producing plants in my yard which I try to protect. Once the berry has formed they will last through the light frosts of fall and sometimes an easy freeze (much like your frozen berry packages). During the day the berry will soften & the birds (& small animals) have a treat.
