Climbing sedum—is it a succulent?
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.”
Can sedum be grown indoors?
Sedum is rapidly gaining popularity as an indoor plant. Stonecrop is tolerant of an indoor environment even in the worst circumstances. The sedum may survive inside with a little extra care. For sedum to thrive, full sun and warmth are essential. The hues in its leaf will pop with lots of sun. Avoid placing the plant near a north-facing window because it requires at least six hours of sunlight every day. Stonecrop will flourish in a container with drainage holes that allow the soil to dry up and drain effectively. The optimal environment for the sedum is a warm, sunny space.
Sedum can it endure winter?
Succulent plants called sedums thrive in climate zones 3 to 9. Sedum is one of the toughest succulents available due to the fact that succulents are notorious for storing water in their leaves. Sedums can withstand hot weather, dry soil, and cold temperatures. Sedum won’t need a lot of winter maintenance, unlike most perennials.
Sedums can be neglected when you tidy up and cut your garden space for the winter. Sedums are hardy plants that can withstand cold and temperatures below zero. Sedums that are standing upright will eventually fade back to the ground, but the surviving stalks with spent flowers will still provide color and food for the birds. Pruning the stalks all the way to the ground is an option. The plant and the spring’s fresh growth won’t be harmed.
Cacti, are sedums?
Everything depends on how they are arranged. For purposes of identification, the gardener just needs to keep in mind the three classifiers of genus, species, and cultivar. A group of closely related species is referred to as a genus.
Within the genus category, species are a more precise classification that have viable progeny. For instance, Sedum is the genus and glaucophyllum is the species of Appalachian stonecrop that thrives in rocky, alkaline soil, respectively, in the name Sedum glaucophyllum.
The sedum that has been chosen for favorable characteristics is further categorized by a cultivar. On the plant tag, Sedum glaucophullum ‘Dazzleberry,’ so the plant would look burgundy rather than green.
Understanding the distinctions between sedum, succulents, and cactus will be made easier by being aware of these classifications. Succulent is a descriptive term for a plant trait rather than a scientific classification. Succulents may retain water in arid regions or soil conditions because some of their leaves, roots, or stems are thickened and fleshy. There may also be plants with succulent characteristics and a typical plant stem within the same species. Numerous plants have succulent traits that enable them to cope with dry environments. Due to their dry origins and special characteristics, succulents can withstand drought.
Another succulent trait that cactus exhibits is the retention of water within the structure of the plant. Typically, cacti have thorns. Hobbyists who raise cacti and succulents frequently distinguish between them based on whether or not they have thorns rather than strictly on the botanical classification, which is sometimes more difficult to perceive. Members of the Cactaceae family include cacti. Confusion is increased since plants may have adaptations to dry circumstances that make them seem related.
Sedum is a genus of flowering plants that also exhibits the succulent traits of having leaves and stems that can store water. Sedums belong to the family Crassulaceae. Due of its stone-like look, sedum is also known as stonecrop. White flowers are present on Appalachian stonecrop. Sedums, which have 600 species in the Northern Hemisphere, include shrubs, annuals, perennials, and creeping herbs. Succulent traits can be found in both sedum and cacti, despite the fact that they belong to two separate plant families.
It might be wise to look for cultivars with succulent traits if one wants to create a rock garden or grow drought-tolerant plants. These plants have interesting body shapes and are lovely. There are many different kinds of flowering, creeping, low-growing, or towering plants that, once established, require little maintenance.
Which plant family belongs to sedum?
In the family Crassulaceae, the genus stonecrop, often known as sedum or orpine, has roughly 600 species of succulent plants that are native to the temperate zone and tropical mountain ranges. For its distinctive foliage and occasionally spectacular flowers, certain species are produced in greenhouses. Low-growing plants are preferred for rock gardens, rock walls, and garden border edging.
Watering
Sedums can withstand droughts but still require some water. They thrive when watered often from spring to fall. Water deeply, then let the soil air dry before adding more water. For the first few weeks, young Sedums will require additional water to grow roots. In many places, established plants merely require rain. When watering, avoid getting the leaves, stems, and flowers wet. Water your plants sparingly during the winter to prevent shriveling.
Plants cultivated in containers frequently need more water than their equivalents planted in open soil.
Fertilizing
Sedums typically just need a balanced organic fertilizer every spring. Feeding is not required as long as the plants are separated annually and given new soil.
Repotting
Sedums in containers do need a similar amount of maintenance to those in gardens. When your plants outgrow their present pot, repot them by transferring them to a larger container that will better hold the plant. Sedum repotting is best done in the spring. Before starting the repotting process, make sure the soil is dry.
Pruning
If Sedum plants are not going too wild and out of control, pruning is not required. After the winter, you can tidy them up a little by removing any dead or broken branches or leaves.
Succulent or not, a stonecrop?
A collection of succulents known as sedum (Stonecrop) is simple to grow and looks excellent in summer and fall gardens. We at Plant Delights Nursery have been growing sedum plants in our hot, muggy, rainy Raleigh garden for over 25 years, so we thought we’d share our knowledge of how to grow sedum plants as well as the names of our favorite species. The Sedum genus is a diversified group that includes straight tall sedums, carpet sedums that form mats, sedums that are hardly drought tolerant and require constant watering, sedums that love the sun, and sedums for woodland gardens. Therefore, it’s crucial to understand your sedum before planting. Although some taxonomists have placed tall sedums in the genus Hylotelephium, we still refer to them as sedums.
Tall Sedum
There are two primary types of sedums for the garden: towering sedums and creeping sedums. Depending on the variety and environmental factors, the erect stems of the tall sedums (mostly Sedum spectabile and Sedum telephium) can reach heights of 1 to 3 feet. Tall sedums have been developed to grow shorter in new varieties, making them less floppy and better suited to the smaller gardens of today. Tall sedum stems are covered with soft succulent leaves along their length, and in the summer or fall, they are crowned by vibrant flower clusters. The symmetrical shape and vibrant flowers of tall sedums have long been reasons for their cultivation, but more recent types also exhibit coppery, dusky mauve, and dark purple foliage.
Where should sedum plants be planted?
Sedum is a perennial succulent plant often known as stonecrop. This succulent can withstand heat and drought because of its thick, water-filled leaves. Sedum requires relatively little maintenance and is hardy in zones 3–10. Full sun and well-drained soil are ideal for sedum growth. It thrives when planted in a garden area that receives either excessive sunlight or insufficient moisture. While upright sedum grows in large clumps with a profusion of tiny blooms, low-growing sedum spreads along the ground and only reaches a few inches high. This plant’s many applications include rock gardens, rock walls, ground cover, edging, and container gardening.
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 color 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 color 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 color 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 utilize 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 color and texture. The “quilt will vary three times a year as the sedums exhibit the colors of their early-season foliage, then their blossoms, and finally their winter leaves in various tones.
