Stonecrop, one of many varieties of sedum, blooms in late summer and early fall. It is classified as a succulent because of the ability of its leaves to store water, and is an ideal plant for the "dog days of summer" when rainfall is at a premium. Depending on the type, it can be a low-growing ground cover, or reach 2 feet high. Not only are the flowers available in numerous colors, but the foliage is attractive as well.
Choose a sunny location with soil that drains well. After the last frost in the spring, set the plant into the ground at the same depth as its dirt enclosure. Water. Space additional plants 1 foot apart. Unless your summer is exceptionally dry, you may not need to water again. In fact, stonecrop may suffer if it receives too much water.
