TheSedumsform a various grouping of intimately 500 mintage and many have been develop to develop hardy and undemanding succulent recurrent plant for the nurseryman . The group divides into two independent type , the blue , rug - forming stonecrops , and the rather taller , erect ‘ ice - plants ’ that have whorl of larger succulent leaves on a thick , un - pronged stem . All have small , star - mould and ambrosia - rich flower , and the glass - flora in particular pull lot of butterflies and bees .
Most of the stonecrops are evergreen and have rich foliage colours that look beneficial throughout the year . While the leaves of the ice - industrial plant decease back in the wintertime , the peak age graciously and the seed heads are an attractive feature in the winter garden .
Sedumsdo well alongside each other in complementary motley planting , and the green , crimson , chocolate , purple and copper - coloured varieties can be plant to form a living tapestry across area of thin , poor soils .
With fleshy stems and leaves that computer memory water , they are drought - tolerant and are idealistic for gay position with freely draining , fragile grime where most plants would give in to evaporation . Both type make excellent ground cover for red-hot , sunny ground that is otherwise unmanageable to protect , though ice - plant spread tardily , so involve to be establisheden massefor an clamant effect .
This clause shows just how easySedumsare to count after , and picks out just a few examples of the amazing change that is usable .
Sedum Care
Stonecrops and ice - plant are great industrial plant for hard , dry station in the garden . Once prove , they are reasonably much maintenance - spare , though ice - plants will do good from being dividing every four to five age . This stimulates more flowering and produces spare plant for elsewhere in the garden or to give to friend .
Light requirements
Nearly all of the varieties require very sunny conditions , though orpine is a woodland plant that prefers some loose shade . Some of the variegated varieties such asSedum alboroseum‘Lemonade ’ will cut in full sun , so will benefit from some light shadiness during the hottest part of the mean solar day .
Watering
Most type ofSedumare drought - kind and require no watering , though a few varieties of the crawl stonecrop are a little hungry , so check the plant ’s prerequisite with the nursery before buying a new motley for a very wry site . The trash - plants will survive ironic conditions , though their ontogenesis may slow down in very dry summers when episodic light watering will give them a boost . None of theSedumsshould be water in the wintertime as they can be prostrate to rot if waterlogged .
Soil conditions
SomeSedumscan survive in almost no ground at all , and they should always be planted into a light and unfastened , well - drained soil . They do not do well in big soils , even if plenty of grit is added before plant . Add a crushed shell , grit or pebble mulch to reflect the sun ’s luminousness back onto the plant and to keep water away from around the pate of the works .
Sedumsare therefore excellent for steep , rocky slopes with little soil . Stonecrops can be planted into crevices in rock and garden wall , and they will spread across the surface . The nativeSedum acrecan often view on derelict urban sites growing on old , crumbling concrete , where it seems just as happy as it is growing in its more natural cliff - top and rocky landscape homes .
Fertilisers
MostSedumsperform well on thin , pitiful soils , where there is less rivalry from other industrial plant , and indeed too much fertility will result in sappy plants that are loath to blossom and can swag .
In pots
TheSedums’requirements for well drain and nutrient - poor soil and their power to tolerate drought make them idealistic for pots and container . The creep stonecrops are peculiarly useful , forming a basis cover around taller plant in assorted plantings , and spilling over the edges to disguise the edge of the container . They are very various and can be grown in containers of all sorts , including stone troughs , wooden box , sinks , old watering hindquarters , or even one-time laundry up pipe bowl or horticulture boots ! More traditionally , they are spring up in terracotta Pan with other succulent such asCrassulasandSempervivums .
pick out a genus Pan that is at least 40 cm in diameter . The deepness need be no more than around 20 centimetre , as the rootage are shallow . There are few rule in prefer and establishing the plants – though it is of the essence that there is dependable drainage , with plenty of drain holes , and the locoweed should be upgrade off the surface with feet to ensure water drains away chop-chop . When choosing the plants , intend about combinations of height , colour and grain , and be imaginative ! Consider varieties that will give some height near the center , with creep miscellany hang over the edge of the pan . It makes sense to select types with standardized tearing motivation , and to focus on drought - tolerant varieties so that the compost can be permit to dry out completely to avoid the temptation to over - water .
Use a gamey compost that mime the thin territory of mountain scree slopes . extra succulent compost can be hold , or make an adequate mix of potting compost such as John Innes No 2 with vermiculite or perlite . verify that the plants have a base of compost to sit on , and aim to end up with the crowns of the plants around the level of the top of the pan , so that piddle has no chance of collecting around them . Pans look good with a cosmetic control surface of crushed rock , coloured marble chips or sea field glass , so when back - filling around the plants with compost leave enough room at the top for a right stuffing . MostSedumsgrow naturally well spaced , so do not overcrowd or allow them to shadow each other : put the plants in about 2 cm apart .
After implant , you could apply a flaccid brush to hit any compost from the leave-taking , body of water well , and then just leave it to its own twist to create a beautiful feature for the terrace board !
Re - potting is generally unneeded , though containers can be restore from time to time by taking out the plants , exchange the compost , and replant with take parts of the plant , perhaps with a couple of raw motley .
Pruning
Pruning is generally unnecessary andSedumscan be kept in tick by cutting back creeping types at the end , or shabu - plants can be tip pruned in spring to reduce the height if needed . Even after the foliation has died back , the skeletal frappe - plant blossom look attractive through the winter , and can be leave until the keep an eye on saltation when they can be cut off to tidy the plant in preparation for welcoming the young summertime ’s flowers .
magniloquent frappe - works that tend towards being straggly or seem to collapse under the weight unit of the flower heads generally respond well to a ‘ Chelsea chop ’ in May , get hold of a third to a half of the stem length . This looks drastic , but the plant life will be stronger and more thickset , and will bring out a hillock of fresh leafage by July and August , though flowering will be later and may be slightly reduced .
Sedum Propagation
It is very easy to propagateSedums . The creeping stonecrops will often root as they fawn , and it is simply a matter of find out a piece with roots , reduce it off and establishing it in a unexampled home . Even without roots , pieces rationalise off the ends of the crawling stems can plainly be lay onto a suited sandy , dampened but gratis - draining compost in pots , or sections insert gently into the compost airfoil will steady down very quickly .
ice-skating rink - plants root well from stem extract aside at the base , or take 7.5 centimeter to 10 cm tenacious piece from non - flowering stem , take off the lower farewell , and insert them gently into a fifty – fifty mix of gritty compost and horticultural sand . young plants can also be made by division of gravid clump once they are four or five age old .
The dependable clock time to put new plant into the garden is from mid March to April , once the risk of frost has passed , or again in September to October . However , wiped out stems or newspaper clipping can generally be carry to settle in toilet in controlled conditions at any time of the year .
Common Sedum Problems
The crowns of ice - plants grown in heavier soils or less well - drained situations are prostrate to decompose in the wintertime , though adding plenty of gritstone may assist . Plants with soft , cockamamie stems and leaves are belike in soil that is too fertile , and oversupplied with nitrogen .
Older specimens of the taller ice rink - plants may start out to die - back from the centre of the clump , becoming straggly as the remaining theme begin to founder outwards . If this go on , furnish unnoticeable staking or supports , and make a note to split that clump the following spring . If a more drastic solution is needed , take the plant out and supercede it with one of the more recent varieties that does not suffer the issue as pronto – ‘ Purple Emperor ’ , for example , is not prostrate to sagging and can be happily left to make gravid clump .
Pests
Sedumsare pretty bullet - proof and rarely suffer any scathe from diseases or pest . Watch out for aphids , though they are seldom a cause for concern for healthy plant growing in their idealistic condition . sluggard and snails are once in a while a job , but the most likely pest is the vine weevil . The weevil ’s larvae chew around stem bases just below the dirt and provender on roots , which slows the plant ’s growing , then make wilting and eventually break down and death . Plants in container are peculiarly vulnerable .
Never put a new , pot - grownSedumin the garden until it has been knocked gently out of its container and examined for the characteristic gap in the root ball . Indeed , this is a stoppage worth carrying out at the garden centre before you even corrupt the flora – and if there is an plague , take your business enterprise elsewhere !
If your plants do bear an irruption of vine weevil , targeted biological command using nematode can be used to avoid contrary effects on good insects . It is an effective organic solution and completely dependable for pets , children and wildlife . body of water the nematode mathematical product into the compost in the former summer , and ensure that the compost is kept at 5ºC to 21ºC and well drained to further a healthy universe of nematodes to set up .

FAQs
What do an Aldi supermarket in Guildford , BMW ’s Rolls - Royce meeting place centre of attention in the South Downs National Park and the Peter Lanyon Building on the Tremough Campus of the Combined Universities of Cornwall have in unwashed ? They all have green roofs , planted with vegetation in a develop sensitive over a waterproofing tissue layer .
Sedumis the most popular choice for planting up these ‘ keep ’ roofs , as it can be difficult to irrigate or maintain them once complete , and the stonecrops thrive on rainfall alone , keep up a concluded cover , and generally look after themselves once found .
You might not want to tackle your house cap , but it is possible to go green and add together aSedumroof to a garden way , garden or shed , especially if upstairs windows await down on it – theSedumcover will make it look more like an extension of the garden than a bare metallic element or feel control surface . However , you will desire to take some professional advice to make certain the structure is robust enough to take the weight before get going the project .
Green roofs can help with sustainable drain , provide additional insulation to the construction , palliate the urban ‘ heat island ’ result , draw carbon paper dioxide , bring home the bacon ambrosia for insects and provide habitat for wildlife more more often than not . Pre - grown carpets ofSedummixtures are available , which can be laid rather like turf , and are potential to let in stalwart , drouth - patient of varieties such asSedum acre , S. album , S. hispanicumandS. relaxum , but establishing your own planting system would be much more fun !
There are a number of nativeSedumspecies in Europe . Most are stonecrop that thrive on the thin ground of sandy and rocky areas , including old quarries and desert urban website .
Sedum acreandSedum albumare two of the commonest in the UK , and the sensationalistic species that you have seen is almost certainly the former . They may not have the yr - round interest of some of the horticultural varieties , but they will grow very well in the garden and in containers give the correct conditions . They are easy to propagate by taking an cozy cut , and channelize the spell home in seal credit card udder . You should get permission from the property owner first to stay within the law .
Please do not take orpine(Hylotelephium telephium)from the natural state . This aboriginal mintage is a congenator of the ice - plant and it is a rather rarefied wild flower these days . Plenty of cultivated variety are uncommitted from baby’s room .
Ice - plants are great for add people of color and texture to constitute on and around the terrace , and ‘ tropic - looking ’ bed are popular . adjudicate usingSedum spectabileto mark the edge between the terrace surface and a edge , and stonecrops in the gaps between pave in less well trodden parts .
In the tropical border itself , try out the architecturalHylotelephium telephium‘Matrona ’ . It has an vertical contour and large , purplish - tinged leaves . The flat horizontal planes formed by its pallid pink flush head harmonise well with the bold vertical line of plant life such as iris and shoulder strap - leaved , tropic - look flora likeCordylines .
The stonecrop is unlikely to affect established plants . stonecrop will shape a mat , but they are ground - hugging , so lean to grow around established plants rather than causing any problem by jumble up or through them . Keep an eye on the site , and the stonecrop can be very easily trim back if you palpate there is going to be an impact on a particularly delicate or low plant .
