Hi bidget i have a small box hedge don't know which one, but last winter it to was tinged by the cold weather and this year,it soon comes back in the spring

Yes agree with Jiffy,always comes back.

The Japanese Boxwood that we grow here turns brownish every winter, and greens up every spring. The color seems to be natural plant antifreeze.

Thanks for that. I hope you are right. It has taken so long to get the plants to join hands!! I would hate to lose them.
