Kabby,
I did not have many Caladiums last year because of the very cold winter of 2014 that almost wiped them out. What few I did have left all seem to return though. So unless we have a very cold winter like that again I expect most of them to return. Before the cold winter they have returned reliably for several years.
I watered the rose bed before planting the new daylilies in it, because it was so dry. The bog still had standing water in places, so I just had no idea what the weather was actually like while I was gone. I got contradictory stories about it from my neighbors on each side of me!
