Could you please tell me if it is frost tolerant.

It tend to die back in the hardest winter weather, but as soon as there is a slightly milder spell it sprouts again

I grow mine in flower tubs and bring it into the unheated greenhouse if it's going to be very cold. It should be possible to have chard almost throughout the year if you give it some protection.
