Gardening: Peonies

BK and I are going to attempt what might be a foolhardy adventure in planting and growing peonies in zone 8b.  We've ordered bulbs from the Hollingsworth Nursery and will be planting them in some new flower beds he has built.  Hopefully we won't have as brutal of a summer like last year (80 days of over 100 degree temperatures!).  Any advice for peony planting?
