Q.Will Cockscomb survive indoors during winter
Will Cockscomb survive indoors during Colorado winter? I would like to bring 10 plants indoors for the winter. I know they are annuals; however, I would like to try.

Once the plants have flowered they will not produce any new plants or flowers. Celosia is an annual. You can however collect seeds for next spring.
Here is a link with more information.
