Question
I just moved to a new house in Boise, ID.  The former owners removed all the grass from the small yard, covered it with gravel, and planted cactus.  There isn't even a tree in the yard and I'm on a corner lot, so there is no shade.  Summer is hot and dry here, and I need to know what kind of flowers will survive the sun while I try to get a couple of trees to grow.  

Answer
Sheila,
I went to www.google.com and found these links for you which I hope are helpful:
