Thanks for all of your replies. Yes, I suppose this won't be a true butterfly garden since I don't want to just let it grow and to allow a bunch of weeds. My neighbors sit out next to this area almost every night, so I'd like it to look organized and not wild.
I think I am going to go with Sally's idea of making an X using stones or bricks. As she points out, that'll create 4 separate triangles and then I can just pick out 4 plants - one for each section. At this point, based on all of your suggestions, I think I should try to pick 3 from this list:
- Butterfly Weed
- Bee Balm - if there is a variety that is drought tolerant.
- Tennessee Coneflower. (Purple Coneflower is much too common in my neighborhood)
- Sedum
- Veronica
- Phlox - Jeana (

For the frontmost triangle, I am considering either:
1) putting some annuals in there such as Zinnias or Pentas and perhaps changing it up from year to year. That would be fun.
Or...
2) I found a website that describes bulb flowers for all 4 seasons. So I could maybe put a mix of those in the ground and then just sit back and relax as they go through their yearly rotation.
Thanks for all of your feedback!
