Sedum reflexum (Blue Spruce Stonecrop), a well-liked perennial with low growth and mat-forming characteristics, is decorated with blue-green needle-like leaves arranged around the slack stems like spruce needles. In the summer, clumps of brilliant yellow, star-shaped blossoms produce a stunning floral show. In hot, dry areas, the robust Blue Spruce Stonecrop can be utilized as a lawn alternative or as an attractive groundcover. It also looks fantastic pouring from containers and spilling over rocky walls. This magnificent sedum, which is tough and drought-tolerant once established, is worth growing for its stunning foliage and brilliant flowers.
- reaches heights of 6-8 in. (15-20 cm) and widths of 12-24 in (30-60 cm).
- The best soils to grow plants in are those with poor to moderate fertility levels, dry to medium moisture levels, and good drainage.
- water now and then after being installed. Keep away from the severe winter rain.
- Perfect as a groundcover or edging plant, rock gardens, or containers.
How is sedum 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.
Size & Growth
The Sedum reflexum is a succulent with blue-gray foliage that can grow as tall as six or eight inches in a short amount of time. The width of a single plant can reach two feet.
The plant quickly expands and develops a dense mat of bluish-green leaves that are arranged on stems to resemble spruce needles.
Flowering & Fragrance
The early summer until the end of the summer, tiny yellow flowers with a star shape bloom in lovely golden clusters. Butterflies find the blooms to be highly alluring despite their mild fragrance.
Light & Temperature
It is simple to cultivate Blue Spruce Sedum in full sun conditions with well-drained soil and little water. Although it can withstand moderate shade, it much likes heat and sunlight.
Watering & Feeding
This drought-tolerant plant uses a tiny amount of water. Only when the soil is dry should you deeply water at ground level or from below.
It is not required to fertilize, but if you want to, you can sprinkle some granular fertilizer on the soil’s surface in the spring.
Soil & Transplanting
Any soil pH is suitable, and the Sedum reflexum prefers sandy or regular soil that drains well. In extremely gravelly, infertile soil, the spruce sedum thrives. The result of rich soil is weak, floppy growth.
Grooming & Maintenance
Mow ground cover plantings early in the spring to promote a more dense growth habit and more blossoming.
Sedum reflexum can be pinched or pruned to promote bushier growth and more blooms when grown in pots or other containers. To multiply new plants, use cuttings.
How much time does sedum take to 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.
When is the ideal season for sedum transplants?
To propagate more of these well-liked plants, whether you have little spreading rosettes or tall Autumn Joy stonecrop, you should be able to divide sedum. Sedums flourish in hot, arid regions of the landscape and brighten up places that are difficult to cultivate with color and whimsical form. Sedum separation is a simple task that will immediately boost the availability of plants that are simple to grow. New divisions take little extra work to establish themselves.
In late fall to early spring, perennial plants are typically divided. When to divide sedum will determine how quickly they recover and take root. Before new growth appears in the early spring, it might be challenging to pinpoint the location of the plant because many sedum die back in colder climates. The optimal time to divide the plants is at that point.
Plant division can improve plant health and increase blooming. Every three to four years, divide your sedum. Additionally, some growers advise splitting the plant into two while it is still developing after blooming. Although recovery will take longer, these resilient little succulents should do okay.
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.
The ideal soil for sedums is…
There are several creeping sedums that work best as stonecrops in extremely dry environments (e.g., Sedum tetractinum, S. scre, S. album, S. kamshaticum and many others). Sedum ternatum, for example, cannot withstand drought, so be cautious when choosing a creeping sedum for a dry location. You should drastically cut back on watering after the active growing season has over to avoid winter rot. When in question about whether to water a stonecrop, err on the side of not watering it at all.
What type of Soil is best for Sedums?
Any kind of stonecrop plant you purchase should be planted in well-drained soil. Sedums that grow tall or creep will both decay in moist, heavy soil. Sedum plants thrive in raised beds, sandy soil, hillside slopes, rock gardens, crevice gardens, containers, and green roofs because to their preference for well-drained soil.
How Much Sun Should Sedums Receive?
Most sedums prefer full or partial sunlight (5 or more hours of direct sun per day). Sedum ternatum is one of a few stonecrop species, which are forest plants that prefer to grow on top of rocks in dappled shade. Additionally, dappled sunlight is necessary for some of the highly variegated sedums (like S. alboroseum ‘Lemonade’) with their light green, yellow, and white leaf.
