Beginner Gardening: my sad, sad looking garden, 1 by mehobbs

After lots & lots of research & planning I ordered a planned garden from Bluestone Perennials. I figured they could pick out plants that would work well together & I'd get more for my money since I'm starting a garden from scratch. My plants arrived 5/22 and I got them planted 5/23. I've watered regulary (sprinkler system) and a week later they all look at least half dead. I also planted a crape myrtle & a couple of forest pansy redbuds the weekend before and their leaves are shriveled and sad. What am I doing wrong??
