I have a ginger plant that is growing from a grocery store ginger. I can see a new ginger tuber coming just above the soil. We are expecting our first strong cold front in Williamson county, Texas. Don't live in the Hill Country. Does it need protecting? Lows tonight are expected to be in the 40's.
Thank You

Welcome to the site!

Mine are growing in containers, they do freeze.

Thank you, mine is in a container. I will take appropriate action.

The food ginger from the grocery store is Zingiber official. All of the Zingibers are deciduous, so even if you protect it from cold, it will go dormant anyway. Hedychiums (butterfly gingers) and Costus (spiral gingers) are evergreen, and will freeze to the ground but come back in spring. ZIngibers, Globbas, Schomburghkias, Curcumas and Kaempferias are all deciduous.

Thank you, I didn't know that. Good information.
