Autumn joy sedum (Sedum spectabile), also called stonecrop, is a hardy, summer-blooming succulent. Autumn joy grows from 18 to 24 inches tall and develops into attractive mounds that are as wide as the plant is tall. The blooms of this sedum are pale pink when they first appear and slowly deepen to scarlet-brown during the fall months. Autumn joy sedum prefers full sun and is hardy in zones 4 to 9.
Choose a location in your garden or yard that receives full sun and has sandy, well-drained soil. If the soil in the chosen spot is too heavy or contains clay, amend with 3 to 4 inches of coarse sand.
Dig a hole that is twice as wide and the same depth as the container that the autumn joy sedum was purchased in. Press the sides of the container until the root ball slides out easily. Use your fingers to loosen any bound roots and place into the planting hole. Replace the soil and pat down well.
Water thoroughly at the time of planting, but not enough to make the soil feel soggy. Continue to water whenever the top inch of soil no longer sticks to your finger.
Stop watering in early fall so that the plant can prepare for winter dormancy.
Clip off the previous year's growth in early spring. Be careful not to damage any of the new green growth at the base of the plant.
