These fast-growing and hardy perennials, once planted, need very little attention. Sedum are perfect for covering barren areas and filling in beds or rock gardens, gardening on slopes, or planting in containers. They thrive in zones 3 - 10, and prefer well-drained soil in sunny locations. They should generally be spaced 6 - 10 inches apart, depending on the variety you choose. Sedum plants come in a magnificent array of colors and bloom types including white, pink, purple, yellow or orange flowers. They are evergreen and retain their colorful foliage during the winter months in warmer climates, lending a festive air to your winter landscape.
