These two have started well for me this year. All my plants spend most of their time in full sun!
Here in Wales full sun means daylight ! more often than not it is cloudy or if we are lucky broken cloud. We very rarely have to worry that they will burn and as long as they are kept well watered they seem to manage fine. My Warpaint that I posted earlier maintained some of it's colour all last summer, mind you it never stopped raining last year.
