Sedumspp.
I grow up in neighborhoods where the ground covers of choice were predominantly wintercreeper , ivy , and periwinkle .
And over time , my eyes construct up a visual immunity to them , like my taste bud did with honeycrisp apples . I can objectively say they ’re keen , but I do n’t get that magical feeling of “ WOW ! ” anymore , sadly .
So whenever I range into sedum plantings in the landscape , I sense like a Thomas Kid finding an Easter egg in the yard : I get extremely excited and marvel if there ’s more nearby .
Landscape succulents are an exciting novelty for me , and when it come to stonecrop , an esthetic mass or mat of it in someone ’s garden is a breath of impudent air .
We join to vendors to serve you find relevant products . If you corrupt from one of our link , we may earn a delegacy .
Where I ’m from , at least , it ’s not arid enough to cultivate many succulents outdoors , keep open for the occasionalyucca .
away from that and sedum , the only places in Missouri I could faithfully find out cultivated succulents were can . A breath of … less - than - fresh air , to be frank .
Stonecrop has fleshy leaves and thick stems for conserving water in red-hot , dry climates . Its blooms are typically headliner - mould and they come in many colors , reckon on the species .
A very various genus , Sedumincludes both upright and creeping variety and add up in one-year , biennial , and perennial forms .
This plant perform as beautifully as it await : it ’ll withstand heat , drought , and understructure traffic . It ’ll grow in jumpy or gravelly soils , and infertile soil wo n’t be a balk . And believe it or not , stonecrop is really cold - tolerant , as well !
If all that sounds appealing , then read on to find out how to grow and take care of these wonderful plants for yourself .
Here ’s what I ’ll cover :
What You’ll Learn
Cultivation and History
Stonecrop can be produce in USDA Hardiness Zones 3 to 10 , but the exact range of zones depends on the species .
As a genus , Sedumoriginates from the temperate zone and tropic spate of Asia , Europe , Northern Africa , and North America .
Stonecrop ’s common name come from its natural tendency to “ snip up ” in rocky areas . The genus nameSedumcomes from the Latin termsedeo , meaning “ to sit . ” This cite the sitting and straggle nature of stonecrop as it clambers over stones .
Sedum nomenclature has a story of unbalance . A new genus , Hylotelephium , was proposed in 1977 as a way of severalise upright stonecrop from its miserable - growing crony .
hand - in - the - dirt horticulturalists are a bit dull to live with name changes than botanic taxonomists , though , so do n’t be surprised if you find some inconsistent genera naming in your upright sedum research .
Confusingly enough , unsloped stonecrop are now taxonomically back with the rest of the sedum … at least in some horticulture circles .
S. sarmentosumhas been used in Asia as a folk medicinal treatment for viral hepatitis and other chronic incendiary disease , and many polish worldwide utilise some species of stonecrop as a tasty ingredient in soups and salads .
Additionally , S. alfrediitakes up cadmium and atomic number 30 from the dirt into its shoot , which makes it a viable option for botanically extracting heavy metals from polluted land and tighten these to non-poisonous stage . And it belong without saying that people respect stonecrop in the landscape painting as a versatile ornamental planting .
Propagation
You ’ve got a few selection when it add up to spread sedum : seeds , cuttings , division , or transplants .
Despite the satisfaction of growing from seed , sow stonecrop seed do n’t always grow genuine . The non - seed options are a surefire agency to end up with the variety of sedum you desire .
From Seed
Sowing stonecrop seeds should happen in spring or summertime . The minimum temperature necessary for sowing is about 60 ° fluorine .
Select a pot or a seed tray , whichever you choose . Fill it with a well - draining substratum such as a mix of three parts horticulture soil , three parts sand , and one part perlite . A potting mix suitable for cacti whole kit too , if you require to pass over clear your own .
Moisten the land , spread the sedum seeds over the soil aerofoil , and sum a very thin layer of vermiculite on top . Lightly spray it all with additional piddle .
Cover the container with deoxyephedrine , white newspaper , or a clear pliant bag . berth in an indoor localization such as a windowsill to divulge it to collateral Light Within for two to three weeks until seedling appear , and then remove the screen . Keep the average moist via misting .
After six to eight weeks , once external circumstance are satisfactory , step by step acclimate the seedling to direct sunlight alfresco .
Start with a half 60 minutes to an hour of being in the sun , then bring the container back inside . Increase the vulnerability time by 30 to 60 minutes every day until the seedlings are conditioned for the fourth dimension they ’ll be spend in the Dominicus after transplantation .
At this point , you ’ll want to for good move them into their newfangled location . verify to use sterile tools and materials in doing so .

From Cuttings
Before preparing your cuttings , you ’ll need to choose a container such as a tray or pot . Fill it with a exchangeable medium to what you might use for grow stonecrop seeds as describe above .
To take a press clipping from stonecrop , thin out three to six inch of stem from a healthy plant in early spring . take away the bottomost leaves and stick the cut end in the growing sensitive .
The cutting does n’t have to be just , it can lie prone as long as the last of the cutting is making contact with the stain .
Mist the medium with water , and keep it damp until the cuttings develop roots , a unconscious process which should take six to eight calendar week .
When you start to feel a cut resist when you pull on it , then you fuck that it ’s developed adequately - strengthened roots . hold back another week or two before you harden them off as describe above .
Via Division
To divide stonecrop , select a mature plant in the spring or fall and grasp it up , being heedful not to damage the roots .
Take the mass of root and gently tease or cut it apart into the desired number of divisions , ensuring that each source glob has aboveground growth attached . At this point , each girl sedum is ready for transplant .
Via Transplanting
The ideal timing for transplanting is the beginning of leaping or just prior to it , when works are primed for raw emergence .
transplant sedum is fairly round-eyed : stab a hole astray enough and rich enough so the antecedent ball can fit with some room to spare in the hole , with the top of the origin positioned just below the soil line .
Place the plant in the hole , fill in the opening with the circumvent filth , and pat it all down unwaveringly . piddle in the transplant , and voila !
For multiple transplantation , you ’ll want to space them out anywhere from six inches to two feet apart . Err on the side of less space for low - growing type , and more space for the upright I .
How to Grow
Now that you ’ve got some sedum quick , let ’s explore how to grow it .
Since this is a general sedum growing guide , these direction will be a spot cooky - cutlery .
Some supplementary research on your selection of stonecrop species will help you find the optimal growing conditions , but for now , the following recommendations will attend you well .
Climate and Exposure Needs
Various species ofSedumare distributed worldwide , and are able to rise in many dissimilar temperature ranges . As a genus , these plant will generally grow in USDA Hardiness Zones 3 to 10 , but the precise zones diverge between species .
Stonecrop does n’t wish excess humidity or wetness . give sedum ’s tolerance for heat and dry soil , stray on the side of strong and ironic over cool and humid . But stonecrop is tough , and it will make do in less - than - ideal conditions .
These flora grow in full or fond sun , but as a general rule , full sun – or at least six 60 minutes of lineal sun per day – results in honest growth .
If your garden ’s patches of full sun exposure are limited , fond sun will do . Just know that the more low - grow and vigorous the sedum species , the more shade it can tolerate before growing floppily , and vice versa .
Soil Needs
Sedums favour thin , well - draining , coarsely - textured soil . This is best attain with coarse Baroness Dudevant , but gravel - heavy soil will work in a speck . The ideal pH for these plants is somewhat acidic to neutral , or 6.0 to 7.0 .
Deviating from the above recommendations will most probably head to problems . Too much wet retention can cause rotting , and a soil that ’s too high in nutrients can make leggy growth .
The latter is n’t a vast effect for low - grow specie , but unsloped variety of stonecrop can become top - impenetrable and fall through upon flowering if the soil is rich enough .
Water and Fertilizer Needs
Supplemental stonecrop irrigation is only necessary for establish flora when the top two inch of soil is dry .
You wo n’t have to irrigate that much … and depend on pelting , you might not have to water at all ! Sedum is pretty drouth - resistant thanks to its succulent leave of absence .
Since stonecrop does well in nutrient - substandard soil , supplemental plant food is n’t necessary .
It conduct restate : too much nutrition effect in feeble and leggy maturation . If you dead must fertilize , mould an inch of compost at most into the stain yearly is more than enough .
Growing Tips
Maintenance
sedum are somewhat depleted - maintenance , but there are some things you could do to keep them looking their best .
sneak living flower head before they pass or topple will strengthen the stem , if you ’re working with less - than - ideal conditions that could result in flopped - over stonecrop .
In addition , pinching spend flush will aid clean up the plant life a bit . But it ’s not necessary , since the dry heyday drumhead will provide wintertime pursuit if left alone .
Here ’s a neat trick you could do with your unsloped stonecrop : take a few specimens in your garden when they ’re eight inches tall and abridge them down by a third . This will result in later efflorescence and an extended flower period overall !
The only effort low - growing species need by mode of alimony is the periodic pruning if they go out of bounds and encroach on other plantings .
Be sure to dispose of your clippings properly : if you just leave them in the garden or chuck ‘ em into random plantings , you could get sedum popping up where you do n’t require them to . Debris left in the garden can also boost pestis and disease pathogens .
Species to Select
TheSedumgenus consists of 600 or so full species – and that ’s a gargantuan amount of stonecrop !
you could narrow the inclination down by deciding between upright and low - grow varieties , but even that leaves a lot of options . Let ’s go over some superior sedums .
Showy Stonecrop
Also known asHylotelephium spectabileorSedum spectabile , showy stonecrop is extremely valued for its ability to stand out as a specimen planting in the landscape painting , whether severally or en masse .
It ’s topped with jazzy lump of red , pinkish , or white flowers , and a group of ‘ em automatically grows into a rounded shape , no pruning require .
As an upright metal money , it reaches 18 to 24 in in height , which fits in nicely with the residual of your recurrent garden .
For optimum ontogeny , cultivate this type of sedum in USDA Hardiness Zones 3 to 10 .
There are some beautiful varieties available besides the standard metal money . ‘ Brilliant ’ is a premium showy stonecrop cultivar with shining pinkish flowers , whileS. spectabilevar.atropurpureahas deep purple leaf .
‘ Autumn Joy ’ is a hybrid betweenS. spectabileandS. telephium , and its stunning year - round interest create it one of the best garden perennials .
‘ Autumn Joy ’
Individual , four - pack , or 10 - large number gallon - size of it containers of ‘ Autumn Joy ’ areavailable from Fast Growing Trees .

Two-Row Stonecrop
S. spuriumis a low - farm species that digest urban conditions signally well .
Reaching four column inch in height – six when flowering – this industrial plant spreads as a dim mat in the landscape . It looks awesome as both a ground screening and a complementary piece of maturation between other plants .
This plant has paddle - shaped folio and rounded toothing on the margins . Pinkish - red flowers protrude beyond the foliage . This stonecrop species thrives in USDA Hardiness zona 3 to 8 .
Notable cultivar let in ‘ Bronze Carpet , ’ with ruby - bronze leafage and pink heyday , as well as ‘ Fuldaglut ’ , which has scarlet flowers and deep red foliation .
‘ Fuldaglut ’
you’re able to get ‘ Fuldaglut’from Nature Hills Nursery .
This species can become invasive in sure zones if it ’s not tight monitor .
Orange Stonecrop
S. kamtschaticumis an evergreen plant sedum that performs well on hillsides , within pockets in Lucy Stone walls , and along borders , providing visual interest in these spaces .
Growing beneficial in Zones 3 to 8 , its idle green leaves are long , scrawny , and toothed on the ends . Flowers are yellow to start , but produce orange ejaculate mind with age , hence the mutual name .
A cultivar worth mentioning is ‘ Variegatum , ’ which has many nerveless lineament . Its foliage is variegated , with blanched leaf leeway that are flushed with pink .
The flowers are also a spot dissimilar : they ’re a deep , more intense yellow than those of your everyday orange stonecrop .

Managing Pests and Disease
As a group , these are fairly bad plants . But that does n’t mean they ’re invincible . Let ’s analyze some likely terror to a sedum ’s health .
Herbivores
human being are n’t the only mammalian that incur stonecrop tasty . timber creatures will also have at your sedum , if given the chance .
Luckily , sedum are somewhat resistant to deer , thanks to their virulent taste . But when cervid get going feed out of food in winter , poor spirit wo n’t deter them from taking some despairing nybble .
You might be able-bodied to protect clumps of upright stonecrop with caging or netting , but for low - growing character that take up a fortune of square footage , forget it .
You ’re well off enclosing your garden as a whole , which will also protect your other plants that deer could nosh on . Read about DIY deer fence in our scout .
Using deer repellant sprays will be less visually noticeable , although rain may necessitate repeat applications .
squirrel and vole will eat sedum , too . For these pests , cage and netting are worthwhile alternative .
They wo n’t have to be as marvellous as the kind you ’d use for deer , but they ’ll have to be unclimbable and sunk a few inch late below the surface of the soil so that rodent ca n’t tunnel their way in .
Rodent sprays can be apply to the industrial plant straight , while rodent - repellent pellets can be applied to nearby dirt surface and water in so the roots are protected from subterranean pests .
Insects
Insects go hand in hand with disease , since they can also be transmitter for pathogens . in good order protecting your stonecrop against dirt ball will go a long way in warding off disease , too .
Also known asOtiorhynchus sulcatus , fledged black vine weevil are half an inch in distance , with a bead - shaped pectus and chickenhearted - haired backstage covers .
The chuck are whitened and kink , with a chocolate-brown psyche . The adults run nocturnally on the foliage margins , while the grubs consume the roots .
Insect morbific nematodes can be applied to the soil to see the larvae .
Beneficial Nematodes
Some high - timbre metal money suited to this purpose , such asSteinernema krausseiandHeterorhabditis bacteriophora , areavailable from Arbico Organics .
Foliar sprays of fluvalinate and/or acephate are hearty options for dealing with the adult , and they should be applied when the grownup are prey , prior to laying testicle . Timing these spray every three weeks in May , June , and July should be sufficient .
stop your country ’s pesticide regulations before acquiring these chemicals . If you could lawfully use them , bring up to the label to ensure safe usage .
Mealybugs are modest , white to gray , segment louse that feed on sap from leafage and stem tissues , which stresses and weakens your sedums . They egest honeydew melon and leave behind wispy blanched clumps of wax on plants , which indicate their presence .
That , plus the assemblage of eggs sacs and the mealy bug themselves , leave the stonecrop looking infested and unaesthetic .
Mealybugs can be remove by handwriting , blasted off with gamy - pressure bursts ofwater from the hosiery , or desiccated by swob a 70 percent answer of scratch alcohol in water system on the pests with a cotton swab .
Neem oil or insecticidal liquid ecstasy work too , and if biological control fathom appealing , then premise ladybugs will help thin mealybug universe .
study more about contend mealybug infestations in our guide .
Scale are itty - bitty insect that fellate the sap out of plant tissues , in a similar manner to mealybugs .
Control is also similar to what you might do with mealybugs : manual remotion , water sprays , isopropyl alcohol , insecticidal easy lay or neem oil , and/or the introduction ofpredatory good insectssuch as ladybird beetle are all valid mean value of scale dominance .
require to take more about scale insects?We’ve got a guide for that too !
Slugs and snails are both mollusc that share many similarity , except snail have shell while slugs do not .
They ’re most active on cloudy or fogged days and at night , and oftentimes the only evidence of their bearing will be guck trails and damaged plants .
Snails and slug actually favor succulent foliage compared to other kind , and will leave behind irregular holes in the farewell and clip plant parts .
beak out slugs and snailswith a gloved hand is in effect for controlling these pest .
If they seem to be cryptic in hiding , irrigate the infested areas in the late afternoon . This will draw them out at nighttime , which will reserve a torch - equipped gardener to pick up and dispose of them in the trash .
Disease
As with insect infestation , unhealthful plants are more prone to succumbing to disease .
In add-on to properly cultivating your stonecrop , keeping garden tools sterilized and throw away of works detritus will help preclude a lot of unneeded infections .
This disease is because of the fungusBotrytis cinerea . It tends to show up on utter or dying plant part as a fuzzy gray mold , which will induce blight if it vex into healthy stem and leaf tissue paper .
Cool and wet conditions are conducive to this disease , along with numb plant tissue like flower heads .
Pinching spent blooms will help to foreclose contagion . antifungal can be used whenever symptom start to show up . Thiophanate - methyl group is an efficacious compound .
A the great unwashed of fungal coinage can cause leaf spot : Cercospora , Colletotrichum , orSeptoria .
The symptoms are strongly defined necrotic patches on leaf , which could cause systemic job if there are lots of them , and/or they begin to merge into enceinte topographic point .
Fungicidal compound such as thiophanate - methyl and atomic number 16 will be useful applications in controlling leaf spots .
have by the fungusErysiphe , powdery mold shows up on foliageas a medley of mycelium and spores .
High humidness can take into account spores to germinate sans H2O . Powdery mildew result in overall weakened plants , thanks to the fungal parasite absorbing food from the master of ceremonies into itself .
Wiping off the mycelium with a wet cloth can abate the symptoms , but true ascendancy can be attain with fungicides . Acceptable fungicidal compounds admit thiophanate - methyl , potassium hydrogen carbonate , sulphur , or triadimefon .
The causal fungi for root rot areRhizoctonia solaniorFusarium . Symptoms include root systems and basal stem that become blackened or brown , rotted , and finally break up . At the soil line , sunken - in lesions could also occur .
Unfortunately , the available fungicides wo n’t do the john like they will for the other disease describe above : they ’re inefficient against root rot . All you may do for septic plants is take and dispose of them .
Rust is a disease cause byPucciniafungi , and it results in rust - shaded spore and small raised spot on stems or leaves . The wall tissue become chlorotic and otherwise discolor , and all of the above results in scrubby plants .
Fungicides such as mancozeb and S will help control rust fungus .
A condition leave in dispirited folio chlorosis , total plant life necrosis , and eventual plant death , stem rot ’s causal fungus isSclerotium rolfsii .
Another identify symptom is a white growth of cottony mycelium that surrounds the jacket at the grunge tune , which may contain very small sclerotia .
sterilisation is the best form of command here : you ’ll have to remove and ruin any infected plant in your garden .
desex the infected soil is all important before you engraft there again . To do this , lie down transparent plastic over the area for four to six weeks . This will effectively cook the land - bear kingdom Fungi to decease .
Best Uses
Sedum ’s durability and versatility do it an idealistic planting for a multifariousness of ornamental gardening scenario .
vertical stonecrop species will shine as specimens or mass planting in repeated garden , while low - grow sedum search esthetically awful as a boundary line , basis cover or makeweight between your other specimen plants .
In world-wide , stonecrop does well on James Jerome Hill , in crushed rock or John Rock gardens , and in the cranny of Edward Durell Stone wall .
Thanks to sedum ’s enduringness against foot dealings , it ’ll endure in the highly trodden - upon areas of your garden . Plus , sedum makes a great stuff for green roofing , if you ’re into that sort of matter .
Also , stonecrop utilizes Crassulacean acid metamorphosis , which allows the flora to undergo photosynthesis during the day , but exchange gasses nocturnally .
This allows the pore to remain closed while it ’s spicy and gay out , which prevents severe moisture loss in arid climates .
An academic understanding of this outgrowth is n’t required for enjoying your sedum , but explaining how the CAM found in your backyard work will make you the whizz of your terrace cookout .
