My FAVORITE! It is so delicate and gorgeous, and so tough! Treat it just like a succulent, which is to say, set it in the sun and forget to water it more often than not. Thrives best in a container, can be left outside all winter and forgotten, and it will still come back. I find it likes a few rocks scattered around to help keep its *feet* dry. It will self-seed throughout the season and fill your container with new babies. Did I mention that this one is my favorite?
Pollinator powerhouse. Loves the sun, but can take a little shade. Thrives in almost any soil and can take a drought. Feeds butterflies and bees during the hottest months. But if you leave the seedheads up, you may be lucky enough to have goldfinches in the winter. And more coneflower in the Spring.
