Sheets of red, lilac, blue, or purple flowers cover common aubrieta (A. deltoidea) in mid spring—and common aubrieta covers just about every low thing that surrounds it all year. At 4 to 6 inches tall and 18 inches wide, this spreading ground cover is a spring classic. Let it spill over rocks or out of walls.
This planting is in Marilyn Munro's garden in Sequim, Washington.
