I am looking for simple, easy to take care of flowers to line along the house. We used to have rocks and a bunch of bushes with thorns and I have just pulled all those up. I am working on getting all the rocks out to move somewhere else. When I'm finished I will just have dirt and want to plant some low maintenance flowers there instead. Any suggestions?

Lilies are a very good choice. You can get them in all colors,and if you do some searching, you can get lilies so that when one is just finishing the bloom cycle, the next variety will begin. Beautiful and very low maintenance.

Also Black-Eyed Susans are a good choice, as well as Purple Coneflowers.
