The new and distinct cultivar of perennial Sedum plant named ‘Night Embers’ is characterized by tight-forming compact clumps, flower stems that resist falling over and opening up in the center of the plant throughout the growing season, medium-sized black-purple, semi-glossy foliage and numerous mauve-pink flowers clustered on huge heads completely covering the plant, useful for landscaping as a specimen plant, container plant, en masse or as a cut flower.
