Sedums are available in many varieties, such as gold moss, Angelina, coral carpet and autumn joy and typically grow in USDA Hardiness Zones 3 to 9. Sedums make nice ground covers and each variety has its own unique color and grows to different widths and heights. While most sedums are planted as seedlings or small plants purchased at a local or online nursery, some gardeners prefer growing them from seeds. Begin growing your sedum seeds in the spring.
Use a planting tray and sow the sedum seeds just below the surface of the soil. Use moist all-purpose potting soil. Put it in a plastic bag and place it in the refrigerator or another cold and dark area (around 34 to 40 degrees F) for three weeks.
Dig a hole outside in the shade that is just deep enough for the planting tray. Set the tray in the hole and put a piece of glass over top. Leave the tray there until the seeds germinate, which should happen within a month. Be sure the soil remains moist during this time.
Allow the seedlings to grow until you can handle them to transplant. Transplant the seedlings in full sun in soil that is well draining. Space sedums according to their maturation size, which depends on their variety. Generally, small sedums are planted about 6 inches apart; medium sedums are planted 12 inches apart; and large sedums are planted 24 inches apart.
