I think you'll be able to manage them, Gale. The temperature at any given time in my area can be erratic, but I've received fall orders when my temperatures were in triple digits. I soaked them overnight in a bucket of water and then planted them in pots. The pots were located where they would get some morning sun, but were protected from mid-day and afternoon sun. After a week or so, I moved where they were getting more hours of sun. They did fine. It's worrisome when the temperatures are that high, but the daylilies managed it pretty well.
