Sedum sarmentosum (Rosales: Crassulaceae): stringy stonecrop, according to the Invasive Plant Atlas of the United States. This map shows the states that have included this species on their list of invasive species or in legislation.
Where may sedum be grown most successfully?
Sedums have everything! This perennial produces clusters of star-shaped flowers that bloom from midsummer to fall, along with lush, luscious green leaves. It attracts pollinators and is simple to maintain. How to plant sedum in your garden is provided here.
About Sedum
Sedum, a genus of succulents with fleshy stems and succulent leaves commonly known as “stonecrop,” is one of the easiest perennial plants to grow. This sedum cultivar is suitable for practically all gardens because it is a hardy plant that thrives in shallow soil.
Based on how the plants develop, we like to split sedum into two primary categories: low-growing sedum and upright sedum.
- Sedum that grows slowly spreads throughout the ground and only grows to a height of a few inches (or less). As a result, they are ideal for use as ground covers along pathways, in rock gardens, or cascading over stone walls.
- Sedum that is tall or upright often grows in tall, upright clumps with dense clusters of tiny reddish-pink flowers in their huge flower heads. They make excellent candidates for border gardens or pollinator gardens due to their height and lovely blossoms. Despite upright sedum’s recent reclassification into the Hylotelephium genus, it is still frequently referred to as a “sedum.”
Although they prefer full sun, Sedum may tolerate partial shade. Plant sedum in full sun to enhance overwintering potential if you live somewhere with long, cold winters (Zone 5 and colder).
Although sedum thrives in sandy or poor soil, it needs to be well-drained to prevent fungus problems. If cultivated in soil that retains too much moisture, it is highly prone to developing root rot. Additionally, overly fertile soil can promote lanky growth, which can cause upright sedum species to bloom with a top-heavy appearance.
When to Plant Sedum
- Typically, sedum is purchased in plugs or pots and then planted in the garden. Sedum is best planted in the spring, after the risk of frost but before the summer heat arrives.
- In early spring, sow sedum seeds in average to rich soil that is well-drained. (Learn more about adding amendments to the soil and getting it ready for planting.)
How to Plant Sedum
- Depending on the kind, space plants anywhere between 6 inches and 2 feet apart. While upright sedums tend to keep more compact, low-growing sedums will quickly fill in any gaps.
- When planting whole plants or divisions, dig a hole deep enough so that the top of the root ball is level with the soil’s surface. Then, insert the plant, and then cover the area around it with soil. Avoid burying upright sedum stems in particular as this can cause rot.
- Planting cuttings: Sedum is easily propagated through cuttings, just like other succulents. Under the right lighting and watering conditions, the cutting should easily root if the cut end is simply inserted into the soil.
- Sedum plants require little maintenance once they are established. Check on your plants frequently over the summer to make sure they are not getting too dry, and water them (sparingly) if necessary. Sedum shouldn’t require extra watering if your area receives rain at least one every two weeks.
- After flowering, prune the plants to keep their shape or confine them to a single location.
- Advice: After blooming, leave upright sedum flowers alone for more winter interest. They will produce lovely seed heads.
- To stop your plants from spreading, remember to divide them in the spring or fall. Divisions and cuttings root easily all summer long.
- Sedum humifusum has stunning, bright yellow flowers and produces an excellent ground cover.
What sedum has the fastest rate of growth?
Russian stonecrop has bright yellow blooms that bloom in the late summer and deep green foliage. It’s a dependable, quickly expanding plant that may be used to cover sunny regions as well as fill in gaps in rock gardens or chinks in stone walls. In the fall, the foliage turns a lovely copper colour.
- Originally from: Siberia
- USDA Planting Zone 38
- : 36 inches tall
- Full sun exposure
Both have started to be used interchangeably. However, the term “stonecrop” refers to a wide variety of Crassulaceae plants that flourish in rocky, arid environments. Sedums are technically plants belonging to the Sedum genus, which has up to 500 species.
Stonecrops are resilient, drought-tolerant perennial plants that are well-liked in rock gardens, pots, and xeriscaping.
Stonecrop and sedum grow quickly. A fast-growing cultivar called “Angelina” can be planted at any time of the year, but it may take a year or two for it to bloom.
Sedum spreads quickly, right?
Sedums can survive in less-than-ideal environments, therefore the author covers a stone wall with a variety of them (identified in chart below).
A creeping sedum may be the ideal plant for you if you want something attractive that can survive with almost complete neglect. Sedums show off where many other plants would be afraid to tread. For instance, they settle in the crevices of a garden wall or pathway, on roofs or the tops of birdhouses with slightly sloping roofs, or even under huge trees where their gigantic roots control the majority of the soil’s moisture. Additionally, they function well in borders, containers, and rock gardens.
Many gardeners have started looking more closely at plants in the genus Sedum as seasonal and protracted droughts become more frequent across the United States. The ground-hugging relatives of Sedum ‘Autumn Joy,’ which is well-known for its late russet blooms, are also gaining popularity.
In my yard, creeping sedums, often called stonecrops, provide endless fascination. Over the course of my many years as a gardener, they rank among the most adaptable, drought-tolerant, and simple-to-grow perennials I’ve ever grown. Sedums really require less work from a gardener as their area grows. These slow-growing plants, which are renowned for their propensity to spread swiftly, prevent weeds from taking root. Since they eventually just fade away, it is not required to deadhead the spent blooms, but it is simple to get rid of old blossoms using a string trimmer. They rarely contract illnesses or pests as long as they aren’t overwatered.
Even the poorest soil may support sedums, and small amounts of soil are really their preferred medium. However, the key to cultivating them is proper drainage. A sedum will be quickly killed by excessive wetness, especially standing water, which will accomplish what no drought can.
Even in the driest conditions, sedums practically never need further water after they are established. Sedums function admirably almost anyplace as long as they receive proper drainage, but they are particularly well suited for gardens in hot, arid regions like the western United States. They can also be found sticking up from boulders or sprouting from only a few inches of scree in cold, alpine environments where they are widespread. For almost every USDA Hardiness Zone, there is at least one Sedum species. The majority of creeping sedums can tolerate little shade but prefer full sun. Native to North America, Sedum ternatum is one sedum that prefers shade and a little bit more moisture than its relatives.
Creeping Sedums
Hardiness: The Northern Hemisphere’s Sedum genus has more than 400 species of succulent annuals, perennials, biennials, subshrubs, and shrubs. Sedums are commonly grown as creeping ground coverings. Each USDA Hardiness Zone has at least one species that can withstand it. Most thrive in Zones 4 through 9. OUTLINE: Five-petaled flowers in shades of yellow, white, or pink lie above mats of succulent leaves that range in colour from green to blue-gray to reddish bronze. In the winter, the leaves of evergreen species take on colours of crimson and russet. PROPAGATION: From spring to midsummer, propagate plants by division or seed in the spring or fall. Plant in rock gardens, walls, recesses in walkways, and pots. You may also use it as a border edging or in sweeps on slopes. The majority of creeping sedums like full sun, although they can also tolerate little shade. They prefer medium to poor garden soil that drains well; once they are established, no additional watering is required. They cannot endure any amount of time in standing water.

Creeping sedums change from season to season
Creeping sedums are attractive for their dependability and lack of fussiness, but I’m also drawn to them for their succulent leaves, lengthy flowering cycles, and, in some cases, year-round attractiveness in the garden. Sedum blooms often come in little, star-shaped clusters that range in colour from white to yellow to purple to pink, and are no larger than an inch in diameter and 4 to 5 inches tall. The carpets of blossoms they generate when planted in large numbers are stunning. Many evergreen sedums, such as Sedum album “Murale” and Sedum stenopetalum, blush to a rich red or bronze colour in the fall and even throughout the winter. These stunning contrasts to an otherwise inert landscape last until early spring. They look particularly lovely on a snowy background.
One of the simplest plants to grow from seed, cuttings, or divisions is the sedum. Stem cuttings or divisions will guarantee the maintenance of a plant’s traits once you’ve found one you like because sedums don’t always grow true from seed. Sedums spread quickly, yet they are not invasive. They are easily lifted and transported because of their thin roots. As long as there is adequate drainage, they may survive the winter in most planters and come out of dormancy in the early to midspring.
I complained as I pulled boulders from the cultivated sections of my father’s fields as a young child working on the family farm in northeastern Maryland. In a fitting irony, decades later I still wander the same fields looking for fascinating stones to use as backdrops and accents for my ever-growing collection of sedums.
A few ways to use creeping sedums
Sedums that are resilient make lovely staples. In a section of my rock garden, I utilise a lot of sedums to simulate a cascade. You can blend several sedums, such as the white-flowered Sedum album, the S. grisebachii, and the yellow-flowered Sedum sexangulare (foreground, first photo below) (background). They perform well in a region that can be seen from above.
These year-round, low-maintenance plants are ideal for containers. You won’t need to bring the pots indoors for the winter because creeping sedums do well in containers. Additionally, because of their drought tolerance, you won’t need to locate someone to water them while you are away. Sedums, like the yellow-flowered S. sexangulare (Sempervivum spp. and cvs., Zones 410, second photo below), can be used as underplantings or in combination with other succulents like hens and chicks.
Make stepping stones or rock walls’ sharp edges softer. Within cracks in a stone wall or between stepping stones, sedums, like S. spurium ‘Fuldaglut,’ grow with almost no soil (third photo, below). Use small, mature seedlings, usually referred to as plugs, and combine with some fine gravel and soil.
Utilize a patchwork of sedums to tame a difficult terrain. Maybe you have a spot where gardening and lawn mowing have never worked well together, like a hillside with compacted soil. It might be the perfect place to use creeping sedums, like the pink-flowered S. spurium ‘John Creech’ and others, to intertwine regions of colour and texture. The “quilt will vary three times a year as the sedums exhibit the colours of their early-season foliage, then their blossoms, and finally their winter leaves in various tones.
How is Sedum Sarmentosum planted?
Stringy A perennial groundcover that forms a mat, stonecrop has creeping, vivid yellow-green leaves and branches that can get as wide as 10 inches. Stem cuttings are a fairly simple method of propagation since the branches take root at the nodes. They can also reproduce by seed or leaf cutting. Plant in full sunlight; while some partial shadow is acceptable, too much shade may cause the plant to struggle. Sedums appreciate sandy or rocky soil and require well-drained soil. Once they are established, they are drought-tolerant, but they still require frequent watering; just make sure to let the soil dry out in between applications. Be careful where you plant this plant because it can develop swiftly and overwhelm young seedlings of other plants. It has shallow roots, making it simple to pick up where you don’t want it to spread.
Plant it where its vivid chartreuse colour can contrast with plants with darker leaves in the landscape, such as rock gardens, garden walls, or border fronts along walkways. It can be used as a lawn substitute in places with little foot traffic or only the foot traffic of children or animals, such as along a driveway or in the space between the sidewalk and the street. Stepping stones can be placed in areas with high foot traffic, and this plant will fill in the spaces admirably. Additionally, it thrives in containers with potting soil for succulents or cacti.
The Latin word sargemtosum, which refers to the plant’s spreading appearance, meaning “bearing runners” or “twiggy.” Graveyard moss got its common name because people used to place it on top of graves to get a sudden flash of cheerful green colour.
Sempervivum sargentii is it a succulent?
The Crassulaceae family includes the evergreen succulent perennial plant Sedum sarmentosum. Graveyard moss, Stringy Stonecrop, and Gold Moss Stonecrop are some of the frequent names for this groundcover plant.
