Autumn Joy sedum (Sedum spectabile) is an easy-to-grow succulent that will thrive in most any soil. Perennials.com describes the flowering process as "green broccoli-like buds in mid-summer, which gradually open into enormous dusty-pink flower heads, finally deepening to rich, bronzy red."
Plant Autumn Joy in sandy, well-drained soil in USDA hardiness zones 4 to 9. The soil can range anywhere from alkaline to acidic. Autumn Joy is not very choosy. It will grow in partial shade but does best in full sun.
Water your sedum once a week for the first month after it is planted. After it is established, water only when the soil is completely dry. Autumn Joy is fairly drought-tolerant. If overwatered, the stems will become waterlogged and rot.
Fertilize minimally or not at all. If your plants have suffered through a particularly long dry season or are planted in extremely poor soil, use a very light dose of slow-release general fertilizer.
Propagate your sedum by "window rooting." Cut the fleshy stems in the fall and lay them horizontally in a sunny window. Within the next month, each leaf node will produce a shoot that can be removed and rooted. During the summer, you can simply snip off a 2- to 3-inch tip from the plant and stick it directly in the soil. Water well, and let it root on its own.
