Sedum is a perennial with thick, succulent leaves, fleshy stems, and clusters of star-shaped flowers. There are many types of sedums, which all have different uses: use low–growing varieties for ground covers and rock gardens and tall varieties for back borders. Sedums are easy to care for and are good for cut flowers.

Planting

  • Plant sedum seeds in early spring in well-drained, average to rich soil in full sun. Space the plants between 6 inches and 2 feet apart, depending on the type. Low-growing and vigorous species will tolerate partial shade.
  • You can also plant divisions or cuttings instead of seeds. Dig a hole so that the top of the root ball is level with the surface, then place the plant in the hole and fill it in.

Care

  • Once established, sedums require little care. Check your plants regularly to make sure they are not dry and water when needed.
  • After flowering, cut back the plants to maintain their shape.
  • Remember to divide your plants in the spring or fall to control their spread. Throughout the summer, divisions and cuttings root readily.

Pests

  • Mealybugs
  • Scale insects
  • Slugs
  • Snails

Recommended Varieties

  • Sedum humifusum, which makes a good ground cover and has beautiful bright yellow flowers
  • Briliant (Sedum spectabile), to add a bit of bright pink to your garden

I am thinking of replacing my lawn with sedums. I live in California. What do you think? I was thinking of using a mix of flats and from seeds.

Sedum is a great groundcover

By Almanac Staff on August 25

Sedum is a great groundcover for dry and hot locations. Just make sure to remove all the grass and kill all the weeds before planting. For successful germination seeds are best started in flats and then transplanted outdoors. You can always sprinkle some seeds between the plant to see if they will come up.

I want to change this patch

By Nanamac McNamara on August 16

I want to change this patch of garden next to the house. All it gets is shade. Should I move all the sedum in my garden?

Shade tolerance depends on

By Almanac Staff on August 19

Shade tolerance depends on the sedum variety. Most sedum plants prefer full sun, though some tolerate partial shade and there are even a couple varieties that grow fine in shade. You can take a sample to a local nursery or cooperative extension to identify it. Chances are, your sedum prefers sun so you'd want to transplant in autumn or early spring.

By Almanac Staff

Dan, Some types of flies are beneficial and deter pests; other types of flies are problems. If you have aphids, simply spray with water or use an insecticidal soap. If you have fungus gnats, your plant may be getting too much water and you need to let it dry out between waterings. It's hard to diagnose without knowing more information (color, size, etc.).

We need to level our deck but the sedums are in the way is it o.k.to cut them back now to save them as they will get trampled on or should I dig them up and

Interesting question, Pat!

By Almanac Staff

Interesting question, Pat! This somewhat depends on the type and from your standpoint the quantity/expanse. You could cut them back now, true. You could let them get trampled and then cut back only the damaged ones. It's usually best not to transplant in summer, as the plants' energy is focused on blooming and sometimes this makes it harder for them to adapt to a new home. Of course, the degree of "trampling" matters, too ... If ours were going to be totally ground into the ground/destroyed, we would definitely move. Sounds like yours are going to get "decked" one way or the other, but fortunately sedum are pretty robust.

I live in Kingston Ontario

By Elaine Carr

I live in Kingston Ontario and this year my sedem is sitting almost on top of the ground. I can actually lift pieces of it off the earth and there are tiny white roots on each piece. The plant is quite old but I have never had this happen before. Any idea what is happening?

I have tri-color sedum

By Tommie T 53

I have tri-color sedum planted on my parkway and it is doing very well. I have noticed a couple plants with clover growing right in the middle. Is there any herbicide that can kill the clover without hurting my tri-color sedum

For small patches of clover

By Almanac Staff

For small patches of clover it's best to hand weed or use a knife to remove them. Push the knife at least 1 inch below the soil, then slice through the roots of the clover plants.

I live in a coastal Maine

By B.P.S.

I live in a coastal Maine town, and have four very large sedum plants that I want to move to a different location. Tall variety, grow to about 3' tall,2-3'wide. They are about four years old, and have grown bigger each year. When the flowers bloom, the stems begin to fall away from the center of the plant. When moving them, should I divide each plant? Or, if planted nearer to each other, will the larger plants hold each other's stems more vertical? Thanks for any advice you can share.

It's recommended to divide

By Almanac Staff

It's recommended to divide tall sedums every other year to control the flopping. Dividing is best done in spring or fall. You can also trim the plants to 8-10 inches tall in June and they will not grow so tall.

is it better to plant

By cliff hatch

is it better to plant sedum seeds in the ground in front of a grave stone or to plant a fully grown sedum plant ?

Sedum is great choice for

By georgewilson

Sedum is great choice for gravestones. Get a low-growing variety so it doesn't get floppy. You can seed or buy a plant; it really depends on how long you want to wait. If you plant in the spring, it should bloom in the summer, but some varieties grow quickly and others grow more slowly.

can you grow new sedum plants

By jaffa hyman

can you grow new sedum plants from the old clippings

Sedum is very easy to

By Almanac Staff

Sedum is very easy to propagate. Snip a piece about 4 inches long that has 3 or more leaves. Remove the bottom leaves and push the cutting into moistened soil mix so that the one leaf is above the surface of the soil. Use a well-draining soil mix or mix sand into regular potting soil.

By name taken

I was given a lovely potted sedum, which I kept on my terrace. Can I bring it inside now that the temperatures are dropping below freezing as the pot is small and I don't want the roots to freeze.
If it starts to regrow indoors will that be a problem for the plant?

By Verla Chambers

I live in Manitoba, the snows have begun, should I "cut back" my sedum? This is my second year of them and do not know what cutting back means. Am I to cut them to the ground?? I appreciate any advice. Thank you.

Sedum should die to the

By Almanac Staff

Sedum should die to the ground in the winter. Cut them down any time--now or late winter or early spring.  When we say cut them down, we mean to the ground. Some people keep wait to prune until early spring as they think the seedheads add winter interest.
In general, throughout the growing season, you can cut back a third of the sedum stems whenever they grow floppy.  When they are 6 to 12 inches tall, you can pinch back their growing tips to encourage sturdy growth (not floppy).
