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.
Can stonecrop be planted in the fall?
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.
Stonecrop will it survive the winter?
Sedums are diverse.
Some ground covers are sprawling, trailing, and towering, while others are neatly mounding. Some of the larger kinds are spectacular when combined with blousy, soft grasses, while the low-spreading to medium forms look lovely in containers. Most of them are worth planting for their foliage, which comes in a variety of shades of green and blue-gray and can develop beautiful colors as the weather turns chilly, even though many of them will produce exquisite blooms in the fall. Many stonecrops, in contrast to other succulents, are quite cold-tolerant and maintain their attractiveness from spring through fall and into winter. Even when they are grown outdoors in pots throughout the winter, some are resilient in temperatures as low as minus 45 degrees Fahrenheit.
In a mixed pot, a single stonecrop plant can look amazing. You may need to explore a while to discover a blend you like because of their wide diversity in habit, form, and color, but you can’t go wrong with practically any type.
Many stonecrops are good at luring butterflies and hummingbirds when they are in bloom.
Sedum and stonecrop interchangeably, right?
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.
Is it simple to grow 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.
How quickly does stonecrop grow?
The ‘Angelina’ stonecrop (Sedum rupestre ‘Angelina’) is a low-growing mat of succulent foliage that is perennial and evergreen. The word “stonecrop” is a Middle English term that describes a plant’s capacity to flourish in rocky, gravelly terrain. Depending on how much sun it receives, the ‘Angelina’ cultivar of S. rupestre has needle-like leaves that is either chartreuse or golden. It blooms with small yellow flowers all summer long. Additionally, the foliage develops an orange or rust hue in the fall.
Although “Angelina” is typically planted in the spring, it may be grown virtually year-round. Although it grows reasonably quickly, it could take a year or two before it blooms.
Does stonecrop last for years?
Hardy and drought-tolerant perennial plants known as stonecrop (Sedum spp.) are well-liked in xeriscaping, rock gardens, and containers. From the ubiquitous, two-foot-tall, long-blooming Autum Joy to the adorable groundcover stonecrops like ‘Dazzleberry,’ stonecrop comes in a range of shapes and sizes.
With stonecrop, what can I plant?
Consider putting hostas in the bed if your Autumn Joy is placed in some shade. They demand the same amount of water and sunshine as sedum. The long, prickly flower stalks of hostas will enhance Autumn Joy’s blossoms.
- Autumn Joy’s light green stems and leaves contrast well with the blue fescue’s spiky, blue-gray foliage.
- Most produce gorgeous leaves that frame your sedum until they flower in the late spring.
Sedum stonecrops: is it invasive?
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.”
Does stonecrop grow better indoors or outdoors?
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.
How is a stonecrop maintained?
Growing stonecrops is a great gardening activity for beginners. They can be grown outdoors or indoors in warm, sunny environments. The stonecrop plant is ideal for perennial borders, rockeries, walkways, and container gardening. Succulents grown as stonecrops rarely experience disease or pest issues.
Stonecrop can be buried only shallowly in the ground since it has shallow roots. Although a mulch of small stones reduces such pests, they cannot endure competition from weeds and other plants.
The plants require a rich, organically amended soil that drains well. While they are getting established, young plants should be watered every few days. After that, irrigation can be reduced, and no more water is needed in the fall and winter. Use unglazed clay pots for planting in containers to encourage the evaporation of extra moisture. In stonecrop, overwatering is the most frequent source of issues.
Throughout the growing season, the plants require a low nitrogen fertilizer to be administered a few times.
How large can a stonecrop grow?
Award-winning Sedum ‘Brilliant,’ which is incredibly well-liked, is one of the toughest and easiest border sedums to grow. This upright type has flat clusters of bright, light pink blooms with long filaments that extend over the ends of the petals that are 3–4 inches across (7–10 cm) in size. They turn rust crimson in the early fall. The foliage is glaucous below, smooth, and light green, and it looks fantastic all year long. This exceptional perennial is simple to cultivate and grows as an 18–24 in. tall and broad (45–60 cm) cluster of succulent, dense foliage topped with blossom buds that resemble broccoli. In the middle to late summer, these tightly packed buds will gradually open to produce tiny, star-shaped soft pink flowers. As they age and die in the fall, these flowers will gradually become rusty red and finally coppery-rust. 1993 recipient of the Royal Horticultural Society’s Award of Garden Merit
