i just got a sundew recently, my second one. the first one died. i'm pretty succesful with pitcher plants and vft so, i really wanted to try another. i've got the pot placed inside a glass fish bowl to help raise humidity, and i;ve got it outside. i live in north GA, and i was wondering if i should leave it outside all winter. i think it is a spoonleaf sundew(but i'm not sure!) how cold tolerant are these plants?
