In the garden

Sedum spectabile 'September Glow' is a succulent perennial in the Crassulaceae, native to China and Korea, that reaches roughly 0.4 m. It carries flat-topped clusters of pink flowers through June to September, providing a clear late-summer display above a mat of blue-green leaves. Plant in full sun and choose soil that drains well; it will grow in sandy, loamy or clay substrates provided they are not waterlogged and remain 'well-drained' or at most moist but well-drained. Its UK hardiness rating is H7 (fully hardy), and it corresponds to approximately USDA zones 5–9, so it tolerates outdoor winter conditions across the UK without winter protection. Use Sedum spectabile 'September Glow' where a low, sun-loving succulent suits the scheme — sunny mixed borders, gravel beds or any spot where summer colour and structural flowerheads are required. At about 0.4 m tall the flower heads sit clearly above the foliage from June to September, making the plant an obvious late-season component in sunlit situations.
