I picked these on Sunday and brought them into the office Monday to liven it up. When coworkers come in and say the inevitable, "Nice flowers," I can waylay them into telling me what some of this stuff is. (They also tell me neat stuff about their gardens. One's son runs a nursery. Another has a wildflower garden around the pool.)
That's how I learned that the purple ones are phlox. Cool. They smell nice too.
