I understand that Gaillardias are herbacous, so yours is trying to go 'dormant' for the winter. Can you plant it out in the soil? Perennial plants are often better placed there, and more likely to survive the winter.

I find they can be temperamental some winters they come through and others they dont. But it would be better either in the ground or in an unheated greenhouse/coldframe.

thanks for the advice, I could plant it out but I was waiting because next few months I am re-giging the boarders. A few weeks ago, I put bubble wrap and fleece around the pot that it's in, to try and keep it from getting to cold, my conservatory is not that warm I might just keep it in the coolest part and see what happens.
