I can't even say that many of my heat stressed daylilies go dormant because they still put out scapes and wimpy little blooms and often while the outer leaves are dying new green is starting to grow like new fans in a clump. I just keep seeing it referred to as summer dormancy so I often use that term myself. I can say that the same plant my not be affected or as badly affected by heat stress every year, while others that don't show it as much some years show it a lot more in other years. In other words my list of the most affected plants by heat stress would not be the same every year. Maybe some had more winter damage that weakens them as late as summer? I really have no idea why.
