Jean, this is what I have in full sun that is not showing stress from:
1. Full sun
2. Heat, we've had temps in the low to mid 90's and only one day of 100 this summer.
3. No rain, and I've watered about 5 times this summer. I also water at night when it has cooled down. Gives them a chance for the leaves to dry out before the sun hits the next day.
I have many that are heat/sun stress right now, growing in the same beds with the ones on this list. Makes it easy to figure out which ones handle sun, heat the best. These are established plants and that might make a difference.
