Actually, no I haven't. I prefer to never grow things in containers in this type of heat ...
The only reason I grow anything in a container is to pot up a plant to grow the root mass so that it is larger so that when I plant something in the ground it has a better chance of success.
High summer temps are not only hard on container plants they are hard on things in the ground, too, but if a plant has a good start, it has a very good chance of finding it's feet and taking off and becoming a permanent part of the garden. I have found that my heucheras come back better when I give them a good start.
