Sedums have it all! This perennial plant has succulent green foliage and produces clusters of star-shaped flowers that bloom from midsummer to fall. It’s easy to care for and beloved by pollinators, too! Here’s how to grow sedum in your garden.

Perennial plants don’t get much easier than sedum, a genus of succulents with fleshy stems and succulent leaves—also called “stonecrop” or “live-forever.” A hardy plant that grows well in shallow soil, there is a sedum variety for almost every garden.

We like to divide sedum into two main categories based on the plants’ growth habits: low-growing sedum and upright sedum.

  • Low–growing sedum spreads along the ground, reaching only a few inches (or less) in height. This makes them perfect for use as a ground cover along paths, in rock gardens, or cascading down a stone wall.
  • Tall or upright sedum tends to form tall, upright clumps that produce large flower heads in tight masses of tiny reddish-pink flowers. Their height and attractive flowers make them good candidates for border gardens or pollinator gardens. A few years ago, upright sedum was reclassified to another genus, Hylotelephium, but it is still commonly referred to as a “sedum.”

Planting

Where to Plant Sedum

Sedum enjoy full sun but will tolerate some shade. If growing sedum in an area that gets long, cold winters (Zone 5 and colder), plant in full sun to improve overwintering capability.

Sedum grows well in poor or sandy soil, but it’s important to have well-draining soil to avoid fungal diseases. It is very susceptible to root rot if grown in soil that holds too much moisture. Overly rich soil can also encourage leggy growth, which can result in upright sedum varieties becoming top-heavy when they bloom.

When to Plant Sedum

  • Sedum is usually bought in plugs or pots and transplanted into the garden. The best time to plant sedum is in the spring—after the threat of frost but before the heat of summer kicks in.
  • Plant sedum seeds in early spring in well-draining, average to rich soil. (Learn more about soil amendments and preparing soil for planting.)

How to Plant Sedum

  • Space plants between 6 inches and 2 feet apart, depending on the variety. Low-growing sedums will readily spread to fill any gaps, while upright sedums tend to stay more compact.
  • Planting full plants or divisions: Dig a hole deep enough so that the top of the root ball is level with the surface of the soil, then place the plant in the hole and fill in around it. Be careful not to bury the stems of upright sedum, as this can lead to rot.
  • Planting cuttings: Like other succulents, sedum can be readily propagated via cuttings. Simply place the cut end into soil, and the cutting should have no trouble rooting under proper lighting and watering conditions.

Growing

  • Once established, sedum plants require little care. During the summer, check your plants regularly to make sure they are not too dry and water (sparingly) if needed. As long as your area gets rain every couple of weeks at the least, sedum shouldn’t need any extra watering.
  • After flowering, cut back the plants to maintain their shape or contain them in one area.
    • Tip: For added winter interest, leave the flowers of upright sedum alone after they bloom. They will form attractive seed heads.
  • Remember to divide your plants in the spring or fall to control their spread. Throughout the summer, divisions and cuttings root readily.

Pests and Problems

  • Mealybugs
  • Scale insects
  • Slugs
  • Snails
  • Birds, deer, squirrels, and voles may nibble on the succulent foliage of sedum.

Types

  • Sedum humifusum makes for a great ground cover and has beautiful, bright yellow flowers
  • ‘Brilliant’, ‘Autumn Fire’, and ‘Autumn Joy’ upright sedum (Hylotelephium spectabile, aka Sedum spectabile) add bursts of bright pink and magenta to your garden
  • ‘Blue Spruce’ (Sedum reflexum) is a low-growing sedum with blue-green, spruce-like foliage and yellow flowers

If I plant several kinds of sedum together, will they eventually all end up alike? I want them to remain individually distinct. Thank you for your time.

If that happens, it will make headlines and history—or so it seems to us. We have not heard that theory and have seen wide varieties of sedum planted together without losing their individuality.

My Sedum has turned a very light green, almost yellow color. It is usually a darker green. We have had a drought so I've watered about once a week. It is Nov, so it should die back soon (I'm in GA), but I was wondering if I need to fertilize it now, to have a healthier plant in the Spring. Thanks for the help.

The foliage is yellowing because it is starting to die back--completely normal. It's time to stop fertilizing to allow it to go dormant. Begin fertilizing again in early spring.

For some reason my GIANT sedum opened up and the center is open to the elements, the effect is not that appealing, however, I noticed that my smaller sedum also did the same thing. I live in Dayton, Ohio and was just wondering if this is normal? Do I need to dig them up and divide? Just wondering in Ohio.

I'm in zone six, can implant sedums in the fall?

My sedum wants to flop in the center when it gets to be about 12 or 14 inches high, so what am I doing wrong. I see others that are blooming nicely and standing up firmly,

There is a little trick that goes a long way toward having strong, standing sedum blooms. About half way through the growing season (before they have bloomed) cut them back to about 6 to 8 inches. It may feel counterintuitive, but it really works! By mid- to late summer, your plants will look like those you are admiring. Also, they can be staked, if necessary.

How would sedums do in a five foot rectangular outdoor planter? Do wildlife (deer, rabbits, etc.) like them? Any ideas about keeping the pests you mention away from the plants? Thank you.

Sedum grows well in containers. The plant is considered deer resistant and most critters will leave it alone. To find out how to prevent some of the other pests mentioned on this page go to
