Silvery, lacy leaves that look like they've been dusted with powder—dusty miller brings an airy coolness to hot-season containers and beds when everything else is cooking in the heat. Pair it with bright annuals for contrast, or let it anchor a container on its own.

Set it out in September or October for fall color, and it'll handle our mild season with minimal fuss. Thrives in sun and tolerates lean soil, so it works as well in a packed border as it does in a pot.
