An established clump of iris is happy in full sun. Usually when my iris orders arrive here in July and August the temps are above 90 and some of the rhizomes struggle to establish a root system in the merciless sun. I pot so I can put the rhizomes where they receive only a part day sun or if they go directly in the ground I try to shade them for a few weeks til cooler fall weather comes. I find watering in containers a little easier. A milk basket does a good job providing shade as do some shingles. If I were planting Hems I would do the same thing......
