That sounds like a great idea!
Yes, if it weren't for "earthkind roses" everything would be dead except the natives... which is why, for back-up, I planted a bunch of Texas wildflowers from Wildseed Farms. I also let the larkspur, blue-stars and winecups come up all over the yard. Just in case my luck runs out, they'll be something here that just might live!
Here's the web-site with the list.
