Sedums are divided into two types based on their growth habits: clumping and creeping. Clumping hybrids reach a height of 1 to 3 feet. Creeping varieties keep low to the ground and extend out a few feet in each direction. Succulent leaves and small, colorful flower clusters can be found on both varieties. Sedums bloom from late summer to early autumn, depending on the variety. The flowers on clumping varieties are stunning because they stand above the foliage. Creeping kinds can produce so many flowers that they transform a garden into a colorful carpet.
Do sedums like sun or shade?
Sedum don’t need much water, and if they get at least 6 hours of sunlight per day, they’ll produce their greatest colors. In thick, mucky, or high clay soils, they will not thrive. If you have some high spots and some low locations in your yard, the higher spots that drain well after a heavy rain will be preferable for sedum, while low spots tend to collect water.
Some succulents thrive inside, but sedum isn’t one of them. They simply require an excessive amount of direct sunshine.
About Sedum
Sedum, often known as “stonecrop,” comes in a wide variety of types and species, making it suited for use in practically any garden design. They’re hardy, easy to care for, and pollinators adore them!
Based on the growth characteristics of the plants, we split sedum into two categories: low-growing sedum and upright sedum.
- Sedum is a low-growing plant that spreads along the ground and grows to only a few inches (or less) in height. They’re ideal as a ground cover along walks, in rock gardens, or cascading down a stone wall because of this.
- Sedum that grows upright forms tall, upright clumps with a dense mass of tiny reddish-pink flowers. They’re ideal for border gardens or pollinator gardens because of their height and gorgeous blossoms. Although upright sedum was reclassified to a different genus, Hylotelephium, a few years ago, it is still referred to as a “sedum.”
How tall is a sedum?
Tall sedum takes off as the weather warms, growing taller and producing flowers. Tall sedum can reach a height of 9 to 36 inches and a width of 12 to 24 inches, depending on the type. Some cultivars, such as ‘Matrona,’ are known for flopping open. What’s the best way to deal with spread sedum? Plants should be staked or clipped back. Both are completed in the spring.
Cut back tall sedum to prevent flopping
Cutting tall sedum stems back by up to half any time from spring to early summer is another strategy to keep them from flopping. Flowers will be smaller, more abundant, and arrive later in the season. I used pruners to cut the ‘Matrona’ in the photo above back by a third, but scissors would also work. Cut stems back at the leaf joint if possible. Two new stalks emerge, one of which will blossom later.
How tall does creeping sedum grow?
Many gardeners recognize upright sedum species, such as Sedum ‘Autumn Joy,’ as good plants for color in late summer and early autumn’s hot, dry days. Several low-growing sedum types, on the other hand, operate well as ground cover plants in hot, arid climates where other plants struggle to survive.
The Sedum genus contains 400500 species known as sedums, or stonecrops, many of which have been widely embraced as garden plants. It belongs to the Crassulaceae family, which is noted for plants with mushy, succulent leaves. Stonecrop gets its name from the fact that these plants not only withstand but thrive in dry, rocky soil. Sedums can grow to be 2 inches tall or 3 feet tall. Some species can withstand temperatures as low as USDA hardiness zone 3, while others are best suited to warmer regions. Sedums come in both annual and perennial varieties, but they’re always fleshy succulents. Sedums store moisture in their leaves, which is why they thrive in arid environments. Despite the fact that all sedums flower, they’re most commonly planted for their foliage, which comes in unique colors of green not found in other plants.
All sedums are incredibly easy to grow and propagate, and the only way to kill them is to overwater them or plant them in excessively moist soil. A single branch or even a leaf stuck in the ground will swiftly root and grow into a new plant in upright kinds. Low-growing sedums spread quickly but aren’t invasive, and their shallow root systems make them easy to remove, making them great ground cover plants.
For your ground cover needs, here are ten sedum, or stonecrop, varieties to consider.
What is the tallest sedum?
“Autumn Joy,” a hybrid created in 1955 by crossing two species, Sedum spectabile and Sedum telephium, is the most popular tall sedum on the market. It reaches a height of about 24 inches and produces enormous broccoli-like flowerheads in the summer. The star-shaped blossoms begin as a pale green color and turn rose pink in the early fall. They turn a darker crimson and then brown as they age. If the brown flowerheads are left on the plants at the conclusion of the growing season, they add winter interest. “Autumn Fire,” a similar hybrid, has the same form but a stronger fall color.
Does sedum spread quickly?
A creeping sedum might be the plant for you if you’re seeking for a lovely plant that thrives in almost complete neglect. Sedums strut their stuff in places where few other plants would dare. They thrive in crevices in a garden wall or pathway, on roofs or the tops of gently sloped birdhouses, and even under big trees where their massive roots capture the majority of the soil’s moisture. They work well in rock gardens, borders, and containers as well.
Many gardeners have begun to look more closely at species of the genus Sedum as seasonal and long-term droughts become more common across the United States. Sedum ‘Autumn Joy’ is well-known for its late russet blooms, but its ground-hugging relatives are gaining popularity as well.
Stonecrops, sometimes known as creeping sedums, provide a constant source of interest in my garden. They’re some of the most adaptable, drought-tolerant, and simple-to-grow perennials I’ve ever grown in my decades as a gardener. Sedums really reduce the amount of work a gardener has to do as they grow in size. Low growers are known for their ability to spread quickly, preventing weeds from gaining root. Although it is not required to deadhead spent blooms because they will fade away on their own, aged blossoms can be easily removed with a string trimmer. They are rarely afflicted by illnesses or pests as long as they are not over-watered.
While sedums may thrive in even the poorest soilin fact, low or little soil is their preferred mediumgood drainage is essential for their growth. Too much wetness, especially standing water, will destroy a sedum faster than any drought can.
Sedums, once established, require almost no further water to thrive, even in the driest conditions. Sedums are a great choice for gardens in hot, arid areas like the western United States, but they can grow almost anyplace with sufficient drainage. They can be found sticking up from boulders or sprouting from just a few inches of scree in frigid, alpine regions. Almost every USDA Hardiness Zone has at least one Sedum species. Although most creeping sedums prefer full sun, they can also thrive in moderate shade. Sedum ternatum, a North American native, is a sedum that prefers a little more moisture and shade than its relatives.
How fast does sedum grow?
Succulents grow at varied speeds depending on the variety. Climate, soil type, watering, and fertilizing all influence the size and rate of growth of a plant. In a pot, slow types will stay small, whereas fast ground cover varieties, such as Sedum, can spread up to 1″ each month during the growth season.
Sedum Care
Sedum plants, also known as Stonecrop, grow best in full sun with little to no water and, most importantly, well-drained soil. For the flower bed and border, there are larger types that grow to be over two feet tall and wide. There are certain old standbys in the cottage garden, such as “It’s Autumn Joy.” Ground cover types in vibrant greens, grays, and reds that may spread swiftly and flower in early summer, such as “Angelina Jolie”. And everything in the middle! They thrive in practically any garden and make excellent container plants. Sedum plants feature succulent leaves that range in size from small needles to larger and fleshier leaves, and are available in a variety of colors and patterns, including gray, green, purple, blue, and even variegated! Butterflies and bees are attracted to them. And, best of all, they are perennials, meaning they will return year after year.
- Always, always, always, always, always, always, always, always, always, always, always, always, always, always, always, always If you’re going to plant them in containers, add some shredded bark or sand to the soil mix to make it more porous. If your garden soil is heavy, fix it or plant them in raised beds and containers.
- Choose containers that complement the look and feel of the plants. To fit the contemporary vibe these plants give off, think concrete, stone, or simple round bowls if you want to go for a succulent garden aesthetic. But don’t let that stop you from utilizing them in any style of garden; it’s a terrific way to freshen things up!
- Although they can survive without water for long periods of time, I find that if they are in well-drained soil, they look best when watered on a regular basis and let to slightly dry out in between.
- They don’t require a lot of fertilizer or a lot of soil. In fact, if you fertilize your plants too much, they will become floppy, with a lot of stem but few leaves and blooms.
- They can tolerate a little midday shadow, but the taller kinds will flip over if they don’t get enough sun.
- Pinch off the tops of the main stems of taller kinds in the spring, when the plant is around six inches tall. This will drive the plant to grow more compactly, which will solve the flopping over issue I stated earlier.
Once you’ve mastered sedum maintenance, experiment with different hen and chick breeds to grow alongside them. They require the same amount of water and fertilizer as sedums and make excellent companion plants. Sempervirens is the Latin name for these succulents, so you know you’re getting the appropriate one. This image from ‘Sunset’ demonstrates how amazing they appear in containers together.
What can I plant next to sedum?
Sedum’s Companion Plants
- Chrysanthemums and asters Hardy perennials like asters and chrysanthemums bloom in the fall.
- Fescue in the color of blue. Autumn Joy’s gentle green stems and leaves contrast wonderfully with blue fescue’s spiky, blue-gray foliage.
Can sedum survive winter?
Sedums are tough succulent plants that can withstand harsh winters. It’s frequently preferable to forget about them over the winter than to over-care for them and cause damage.
