Sedums, like Hostas and have become staples in American perennial gardens in recent years. And this one, Autumn Joy, is the one responsible. This incredible plant is now at or near the top of everyone's list of the best perennial flowers of them all. Nothing beats it for late color in the border.

Sedums add color from midsummer through early fall, when most other flowers are waning. And Autumn Joy, particularly, lights up with bright pink to orangey flowerheads giving any garden a needed lift for a long period. Like other valuable mainstays of perennial display, the bloom lasts for weeks and weeks.
