Charlotte Weidner |

With upwards of 500 different Sedum varieties, this Crassilaceae family member, also commonly known as Stonecrops, are now offered in so many colors, growing zones, and sizes for the home gardener and commercial landscaper to choose from!

Sedum is a perennial with thick, succulent leaves, fleshy stems, and usually star-shaped flowers. Some have fun, colorful leaves and others are simple and succulent looking! These specimens are extremely versatile!

They work great as a focal point for your garden, a ground cover, a container plant, or a replacement for grass! They fight against weeds, forming dense mats that choke out unwanted plants. Plus they save water, are xeric and drought-tolerant, and are even great for drawing pollinators and Firewise landscaping!

Types of Sedum

The two categories Sedums plants are divided into are low growing and upright.

Low-growing varieties are shorter, ground-hugging and spread wide, making them perfect as a weed-blocking groundcover. People love to place these in cottage gardens or in between garden stepping stones. Use these creeping plants to cover dangerous and hard-to-mow hillsides and slopes. They’re known for being amazing green roofs as well!

Upright Sedum forms in clumps that grow vertically and don’t spread too wide. These are popular for perennial borders or even planting in pots! Adding upright long-lasting color to Rock gardens, dried and cut flower beds, or in tough firescaping landscapes

Frequently Asked Questions

Do Sedums like sun or shade?

Sedum does amazing in both full sun and partial shade, however, you’ll enjoy way more blossoms and deeper coloration when they’re planted in at least 6 hours of sunlight a day!

Does Sedum spread quickly?

The widest spreading Sedum include Coraljade, Night Embers and Back in Black. Autumn Joy and Lemon Ball, Red Carpet and Dragon’s Blood are among the fastest-growing Sedum.

Does Sedum come back every year?

Sedum are hardy ‘tender’ perennials meaning the tops die back in winter and then regrow in full, bigger and better each spring. Clean the mounds in late autumn after the stems and leaves have died back.

Where is the best place to plant Sedum?

Shop Sedum
You can grow Sedum best in a full sun location in sandy, rocky or regular well-drained soil that has moderate moisture once established. Mulch soil in very hot climates and provide a slow-release organic fertilizer.

Sedum offers spring, summer and fall interest. Sedum foliage is attractive during the growing season and many of them are adorned with beautiful flowers in early fall. Some Stonecrop sedums are left standing during the winter months and the plant stalks add a vibrant appearance to a winter landscape. Along with a beautiful plant, the added benefit of sedums is the butterflies they will attract.

In terms of easy to care for, low-maintenance groundcover, this genus is a rockstar. Enjoy your time planting, growing, and spreading your favorite Sedums!

Happy planting with help from NatureHills.com!

Frequently Asked Questions

Are somewhat regular fertilizations actually bad for sedum?

Yes, regular fertilization can actually harm sedum plants. These drought-tolerant succulents are adapted to poor, lean soils and excessive nutrients cause them to produce weak, floppy growth that's prone to flopping over and disease. Over-fertilized sedums also tend to spread too aggressively and may not flower as well. Skip the fertilizer entirely or apply a light dose of balanced fertilizer just once in early spring if your soil is extremely poor.

Is sedum like regular mulch in that it's bad to put right up against a plant, and can it cause the stem to rot?

No, sedum is a living groundcover plant, not mulch, so the same stem rot concerns don't apply. However, low-growing sedum varieties can spread aggressively and may compete with nearby plants for water and nutrients if planted too close. When using sedum as groundcover, plant it at least 6-12 inches away from the base of trees and shrubs to prevent crowding. For best results, give sedum its own designated space rather than mixing it directly with other plantings.

Can sedum be planted around peonies, lupines, columbine, clematis, hyacinths, and viburnums?

Yes, sedum pairs excellently with these plants as companion plantings. Low-growing sedum varieties work particularly well as groundcover around taller perennials like peonies, lupines, and columbine, while upright sedum varieties complement the structure of viburnums and clematis. The key is matching moisture needs - plant sedum in well-draining areas and avoid overwatering zones near hyacinths. Choose sedum varieties rated for your hardiness zone and plant them 12-18 inches away from main plant stems to allow proper air circulation.

What sedum varieties are best for dry, sandy, poor soil with rocks, and do they mind mulch keeping the ground wet?

All sedum varieties thrive in dry, sandy, rocky soil since they're naturally drought-tolerant succulents that prefer well-draining conditions. Low-growing varieties like Angelina Sedum work exceptionally well in rocky areas and poor soils, forming dense mats that actually help prevent erosion on slopes. Avoid mulch around sedums as it retains moisture and can cause root rot in these xeric plants. Instead, use gravel mulch or leave the soil bare to maintain the dry conditions sedums prefer.

How much fertilizer do sedums need, and which varieties require it?

Sedums are naturally low-maintenance plants that rarely require fertilization, as excessive nutrients can actually cause them to become leggy and lose their compact form. Most varieties thrive in poor to average soil conditions without any supplemental feeding. If your sedum appears weak or pale, apply a balanced, diluted liquid fertilizer (10-10-10) at quarter strength once in early spring. Skip fertilizing established sedums in rich garden soil and focus instead on providing good drainage and full sun exposure.

How do you propagate sedum using stem cuttings, divisions, or rosettes?

Sedum propagates easily through stem cuttings taken in spring or early summer - simply cut 3-4 inch pieces, let them callus for 24-48 hours, then plant directly in well-draining soil. For divisions, dig up established clumps in spring and separate the root sections, ensuring each division has both roots and shoots. Rosette-forming varieties can be propagated by gently twisting off individual rosettes and planting them immediately. Water sparingly after planting and expect new growth within 2-3 weeks.

Why does S. 'Autumn Joy' flop over, and how can you prevent it?

Sedum 'Autumn Joy' flops over when it receives too much nitrogen fertilizer, grows in overly rich soil, or doesn't get enough sunlight (less than 6 hours daily). The heavy flower heads become top-heavy by late summer, causing the stems to bend and collapse under their own weight. Plant 'Autumn Joy' in lean, well-draining soil without added fertilizer, and provide full sun exposure. If flopping continues, cut stems back by one-third in early June to promote sturdier, more compact growth.

How do you care for and fertilize a tricolor sedum in a pot indoors?

Place your tricolor sedum in a bright, south-facing window with at least 6 hours of direct sunlight daily, and water only when the soil is completely dry to prevent root rot. Use a well-draining cactus or succulent potting mix and fertilize monthly during spring and summer with a balanced, diluted liquid fertilizer at quarter strength. Indoor sedums require temperatures between 65-75°F and benefit from moving outdoors during warmer months. Allow the soil to dry completely between waterings and reduce fertilizing to every 6-8 weeks in fall and winter.

My autumn joy sedum gets so big it flops over—how far back can you prune it in early July, and does it recover?

You can safely cut Autumn Joy sedum back by half to two-thirds in early July without harming the plant. This pinching technique, known as the "Chelsea Chop," will reduce the final height from 24 inches to around 12-15 inches and create sturdier, bushier growth that won't flop. The plant will quickly recover and still bloom in fall, just with more compact flower heads on stronger stems. Make clean cuts just above a leaf node for best results.

Can Chinese sedum be planted as a ground cover in full sun around an above-ground pool?

Yes, Chinese sedum (Sedum tetractinum) works excellently as ground cover around above-ground pools in full sun conditions. This low-growing variety spreads to form dense, weed-suppressing mats that thrive in zones 4-9 and handle reflected heat well. Plant 12-18 inches apart in spring after frost danger passes for quick establishment. Choose this variety for its drought tolerance and ability to create attractive, maintenance-free coverage in challenging sunny locations.
