I have MIP in full sun all day in a very prominent spot, but she is not doing as well as would like. I also had Mme. de Sevigne (which may be MIP) in an almost identical spot, but I moved her to a place with relief from scorching afternoon sun, and she seems to be happier already. So, does MIP appreciate relief from scorching afternoon sun?
I'm not really having the best luck with bourbons yet.
