Clint that does look great I like the idea of annuals mixed with sedum!
Cinta - man that looks terrible, I'd contact the folks you bought it from especially since you have a pic! Lynn is probably right that it'll come back but it is still wrong to send something looking so poorly!
I have found many of my sedum prefer mixed shade rather than full sun! I have most in pots and that may make them more susceptible to drying out and hot sun (I'm talking about the groundcover types not the tall types)
