Abstract
A new and distinct ornamental perennial Sedum plant named ‘After Dark’ is characterized by tight-forming, medium-sized domed mounds with vertical stems producing deep-purplish-black leaves. The deep-purplish-black stems are highly branched, remain dense in the center, and resist lodging in the summer heat and rains. Numerous purplish-black flower buds open to show off garnet-colored flowers nearly completely covering the top of the plant and later display the dark red carpels. The new plant is useful for the landscape in containers, as specimens, or en masse.
