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 is the rate of sedum spread?
Climate, soil type, irrigation, and fertilizing all affect how big and fast a plant grows. While fast-growing ground cover species like Sedum can spread up to 1″ each month during the growing season, slow varieties will stay neat and compact in a pot.
How can you help sedum spread?
A: To give your new sedum a good start, it’s more crucial that you create hospitable soil with sufficient drainage. Sedum will root and expand through the bark without any problems if you choose varieties that can withstand heat and drought and water them thoroughly during the first summer and autumn. A gravel mulch works nicely for sedum as well.
Will sedum spread far?
There are two types of sedum: clumping and creeping. Several feet of ground were covered in sedum that was creeping. Sedum clumps can reach heights of 1 to 3 feet. The easiest thing to do is to refer to the label on your plant, depending on the variety and how rapidly you want to fill your garden area. Tall growing sedum should generally be spaced 1 to 2 feet apart. Creeping sedums should be spaced 6–12 inches apart. Sedums don’t develop deep roots as they get older. Without becoming invasive, they can be surrounded by other plants and placed close to buildings.
Do Sedum Spread?
Sedums that clump together do not spread because they become tall. Varieties of creeping sedum are known to cover the ground quickly, which actually aids in weed management. The plant will self-produce new cones at the base of adult plants and from seeds. By cutting off new growth at the plant’s base, you can stop the spread. A compact stem and thicker growth will result from this.
Will sedum suffocate nearby vegetation?
This tasty and fragrant herb provides surprisingly effective ground cover. The fact that insects dislike the smell of rosemary and attempt to avoid it is another advantage of the herb. It thrives on nutrient-poor, arid soil and is quite drought tolerant. It tumbles over on slopes and overhangs due to gravity, erupting in fountains of lush vegetation.
Dragon’s Blood Sedum
The amazing deep crimson hues of this ground cover plant darken over the summer and fall. With its thick leaves, it suffocates weeds and spreads swiftly. Given that it may grow up to six inches tall, this ground cover alternative might need to be pruned to a suitable height.
Sedum seeds from Outside Pride’s Dragon’s Blood will undoubtedly do the trick. Since this plant develops quickly, the 5,000 seeds in this packet should be plenty to cover the majority of lawns.
Sedum: a reliable ground cover?
Sedum ‘Autumn Joy’ and other upright sedum types are well known among gardeners as great plants for adding color to the hot, dry days of late summer and early autumn. But in hot, arid regions where other plants struggle to survive, a number of low-growing sedum types also make excellent ground cover plants.
The Sedum genus contains 400–500 species, often known as sedums, or stonecrops, and is a member of the Crassulaceae family, which is distinguished by plants with thick, succulent leaves. Many of these species are commonly used as garden plants. Stonecrop refers to a group of plants that not only withstand dry, rocky soil but actually thrive in it. Sedums grow to a height of between 2 inches and 3 feet. While some species do well in warmer temperatures, others are only hardy up to USDA hardiness zone 3. Sedums can be annual or perennial, but they are all fleshy succulents. Sedums function so effectively in arid environments because they retain moisture in their leaves. All sedums have flowers, but they are mostly grown for their foliage, which has fascinating green hues that are uncommon in most other plants.
All sedums are incredibly simple to grow and multiply, and the only way to hurt them is to overwater them or place them in soil that is too wet. A single branch or even a leaf inserted into the ground will immediately take root and grow into a new plant with upright variations. Low-growing sedums are excellent ground cover plants because they quickly cover the ground, are not invasive, and have shallow root systems that make them simple to remove.
For your ground cover requirements, here are 10 sedum, or stonecrop, varieties to take into account.
Fun Fact
Many of the plants marketed as sedums are no longer considered sedums in the botanical sense. Plant biologists routinely shift species to new genera, and on occasion they will eject plants from an excessively big genus and create a new one specifically for them. In the horticultural industry, sedums are still frequently used to refer to a group of plants in which some common species have been moved to new genera. For instance, the well-liked sedum “Autumn Joy” is now officially known as Hylotelephium “Autumn Joy.”
What causes my sedum to fall over?
A man’s fist-sized or even larger bloom cluster is possible on some sedum plants. The large flower can typically be supported by the top-heavy sedum, but occasionally the flower will droop to the ground or the stalk may even shatter.
A soil that is too rich will result in weak stems. Sedum plants can tolerate difficult growth circumstances and can even flourish in sand or other abrasive soil. The stems will bend in rich, wet soil, and you’ll see your sedums toppling over. Before planting the succulents, add some sand to the site soil to avoid this.
In low light conditions, Sedums may also have spindly stems as they reach for the sun. Make sure that these succulents receive enough sun.
Do you need to trim the sedum?
Sedum is a resilient, low-maintenance plant. Even if you don’t pay attention to it, it will still grow. Sedum does not require pruning, however doing so will make your plant appear better and grow healthier. Larger sedum plants, sometimes known as clumping plants, can grow up to 24 inches tall. It will benefit from “pinching back to control over growth and toppling of the plant” when there are clusters of blossoms. Low-growing sedum, also known as creeping sedum, spreads over the garden area and grows to a height of a few inches. To limit the spread, some trimming will be required. Sedum can be pruned to encourage sturdier stalks, which can hold the weight of the blooming clumps. While pruning will postpone blooming, it will also aid in preventing the plant from becoming unmanageably large.
Is the sedum ground cover walkable?
Sedum groundcovers are excellent for sunny, exposed areas since they are drought- and heat-resistant. These hardy plants are strong enough to withstand foot activity and require very little maintenance. If you want to cover bigger areas, check for sedum “tiles” that you can spread out like sod or tuck individual plants between pavers. Sedum comes in a wide range of sizes and shapes, but the best groundcovers are the shorter, creeping types. Such kinds as “Dragon’s Blood,” “Tricolor,” “Blue Spruce,” “Kamtschaticum,” or “Fuldaglut” should be sought out. The majority of sedum groundcovers also produce lovely, bee- and butterfly-attractive blooms in the late summer.
Full sun to partial shade, well-drained soil, and drought-tolerant plants are ideal for growing
How large can sedum grow?
Sedum plants require very little maintenance or attention, so keep that in mind when cultivating them. They will flourish in environments where many other plants do, but they will also thrive in less friendly environments. They are perfect for the area of your yard that receives either too much or too little water for other plants to thrive. Because many gardeners make the joke that only stones require less care and thrive longer, sedum is also known as stonecrop.
Height varies across Sedum types. The biggest can reach heights of up to 3 feet, while the smallest are only a few inches (8 cm) tall (1 m.). Sedums are widely employed as ground coverings in xeriscape gardens or rock gardens because the vast majority of sedum types are shorter.
Hardiness varies amongst Sedum cultivars as well. While many can survive in USDA zone 3, others require a warmer environment. Make sure the sedum you plant is appropriate for the hardiness zone where you live.
Sedums don’t require additional fertilizer or water. More harm can be done to plants by overwatering and overfertilizing than by not watering or fertilizing at all.
Sedum Care
Sedum plants, often known as stonecrop, do best in full sun, with little to no water, and, most critically, on soil that drains properly. For the flower bed and border, there are larger kinds that reach heights and widths of exceeding two feet. Old favorites for cottage gardens include “Fall Joy. Bright green, gray, and red ground cover kinds that spread swiftly and blossom in the early summer include “Angelina. everything in between as well! They are excellent container plants and do well in most gardens. Sedum plants feature succulent leaves that can be any color—gray, green, purple, blue, or even variegated—and can have anything from tiny needles to larger, fleshier leaves. Bees and butterflies adore them. The nicest part is that they are perennials and return year after year.
Here are a few expert recommendations for growing sedum plants that will look their best:
- Use a well-drained soil at all times. If you’re planting them in containers, make the soil mixture very permeable by adding some shredded bark or sand. Grow them in raised beds and containers if your garden soil is heavy, or amend it.
- Consider how the plants will feel while selecting your containers. To fit the modern vibe these plants exude, think concrete, stone, or simple round bowls if you want to create a succulent garden effect. However, don’t let that deter you from utilizing them in any type of garden—this is a fantastic way to modernize!
- Although they can go without water for extended periods of time, I find that if they are in well-drained soil, they look their best with moderate watering and a little bit of drying time in between.
- They don’t need rich soil or substantial fertilizers. Your plants will really become floppy with lots of stems but few leaves and blossoms if you overfertilize.
- Although the larger kinds will fall over if they don’t get enough sun, they can tolerate some afternoon shadow.
- Speaking of taller types, snip off the tops of the main stems in the spring when the plant is about six inches high. This will make the plant grow more tightly, which will solve the flipping over problem I stated earlier.
Try out various varieties of hen and chicks to plant with your sedums after you have the caring for them down. They are excellent sedum companion plants because they share the same needs for water and fertilizer. These are known as Sempervirens in Latin, so you can be sure you are purchasing the correct succulent. They look fantastic together in containers, as this image from “Sunset” demonstrates.
Where should sedum plants be planted?
Sedum, often known as “stone crop flower,” thrives in full to part sun. While creeping varieties can thrive in partial shade, taller hybrids require full light for the finest flowering.
Soil: Sedums prefer a pH range of neutral to slightly alkaline soil that is extremely well-drained. Root and stem rot can result from wet, heavy clay.
Tall growing sedums should be spaced 1 to 2 feet apart. Depending on the kind and how rapidly you want it to fill in an area, space low-growing, creeping sedums 6 to 12 inches apart.
Sedums should be planted in the spring after the risk of frost has passed. Till the end of the summer, you can still plant transplants in northern regions. Planting season is spring or fall in drier regions.
