I am learning a lot about coleus here, but one question I have not seen answered, and perhaps I have just missed it - is about how cold a coleus can get and still survive. I just bought some beautiful plants at Costco (yeah, I know... not the best way to go!) and one is already dead, the next is not doing well. I have left them outside, but after reading the threads here, I am thinking that even though we are getting up into the 80's some days, and stay in the 50's other days, perhaps the nights dropping into the 40's are too cold yet? Should I bring them in for a while to nurse back to health? They are in light plastic "pots" about 6" in diameter at the most.
