I'm going to cheat a little here. I mentioned I'm starting a butterfly garden this fall, but most of the plants will be planted in the spring. Research is the key right now.
So I came across this video on Youtube that I think I'm going to refer to when I go out plant shopping. I have some sedum right now, and I've also put out seeds for butterfly weeds. So I've got two of the plants for a head start. I think I have a purple cone flower as well somewhere in my yard. Have to check that out.
Enjoy the video and if I find videos or articles from time to time that I think will help you in your landscaping, I'll add them as well.
