Hi Gmb and welcome to GoY. If is really hot in Connecticut right I'd suggest waiting until autumn. Otherwise so long as you have neural to acidic soil and can keep them well watered after you plant them I'd simply do so now.

Of course, you are in a heatwave, aren't you, Gmb. Difficult to remember that in cold, wet Britain: send them over to Scotland and they will be fine ;-(((.
Yes, I would keep them in the shade for now, well watered and misted in the evenings
