Planting, Growing, and Caring for Sedums

Written By: Catherine Boeckmann Executive Digital Editor and Master Gardener

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.

About Sedum

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, this 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

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-drained 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-drained, 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.

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

Hi, I live in Southern California and have been trying to grow tri-colored sedum in the parkway between the street and the sidewalk in very sandy soil that I amended with some compost. (But not a lot.) I read that this kind of ground cover is so easy to grow, but I've been trying to grow it for a year and a half, and it has actually died back from the amount I planted. I think I was overwatering it at first (twice a week), now I may be under-watering it (once a week). And the area is filled with weeds (clover-like stuff which is impossible to pull because there are so many and they have thin stems, crab grass, dandelions and more) that I have been pulling out (except for the clover). I don't know how to kill the weeds without also killing the sedum. And I don't know how to get the sedum to grow. Can you help me?

Will the seed heads that I have on my plants at the end of winter grow? I never cut my plants until the spring in case they will reseed.

You have the right idea by cutting the plants in the spring, but no, they will not reseed.

can they be brought inside for the winter? They are the Angelina Sedum. They do not bloom, but they spread anywhere can touch dirt. If I can bring them inside, where are the special caring for them? Thanks

Hi, Bea, like most sedum, Angelina is winter hardy. Specifically, this is hardy in Zones 3 to 11—just about everywhere. You could surround it will a bit of winter mulch (leaves), which almost any plant appreciates, but special consideration is not required.

I live in Washington State and I want to grow a sedum plant for my plant biology class. I want to get sedum brilliant but I don't know if it will grow in my lawn. Should I plant it in a corner of my lawn and put it next to the sidewalk so it can get full sunlight?

Hi Skyler,

Seedums need full sun. Find the sunniest spot and prepare the soil with a bit of compost. Fall is a good time to plant seedlings but if you have seeds you need to wait until spring to plant.

I have just cut back our Sedum for the winter. Can it be dried to use in vases or does it need water like other cut flowers?
<a title="View user profile." href="/author/editors">The Editors</a> Fri, 10/10/2014 - 11:30

Sedum flowers do well as fresh cut flowers. If you dry them, hang them upside down in a dry warm spot. The flowers will dry fine but the fleshy stems may take a little longer.

I bought my plant at a lawn sale. It says 'Sedum' on a piece of masking tape on the pot. The plant stems grow about three feet tall. The leaves are quite chewable with lots of green/chlorophyll, but no particular taste. I've been including a dozen thumb-size leaves in my veggy smoothies. Is that advised against? Thanks in advance.
