Another green roof hack – a customers project – a capable roofer built this for his young son ….its in the middle/end of his garden as you’ll see from the pictures – his main concern was to ease the visual impact for his neighbours so chose to add sedums to the flat roof. No water added, after a while the pictures show an amazing roof ….the Sedumshack way. We recommended he go to a local plant nursery to recycle plug trays(256 trays) which were cut to fit – they ensure good drainage and will last for decades when dark.
how many plants are needed …
This answer depends on the plants used …as a very rough guide…
We suggest 64 per metre for 1 year coverage (8x 8)
We suggest 49 per metre for 2 year coverage (7 x 7)
We suggest 36 per metre for 3 year coverage (6x 6)
However, this number also depends on whether they are evergreen or deciduous – i.e. the variety.
Evergreen plants range from tiny-leaved, close up, compact plants (like blue bubbles) that may need 150 per metre for instant coverage …down to just 25 per metre for the more vigorous , larger kinds (spruces)…. so consider this also into the equation ……we group the vigour( ground covering ability ) like this ….
First listed are the slower growing, smaller plants needing a denser planting to achieve coverage….
These are all evergreen and flower in a mix of whites, soft pinks or yellows over summertime. For a ‘viewed from close up’ location these are all we recommend…-
We sell a popular 36 plant mixed selection to include the splash and superstar plants, but stay low if you truly want 12 month evergreen.
Our Splash and Superstar sedums need much more room – and need a ‘big handful size’ area to live in…. but not allowing anything else to share this space because they shade the ground below. Great for larger areas , not for tight spaces unless they can be planted at the sides to grow away and over the edge. If this is wanted then some splash Sedums will add super super summer colours.
Where to grow sedums?
Garden Sedums can be used in many locations where few other plants survive due to extreme drought or hard-frosts freezing thin substrate.
bike sheds or roofs ,

This is the result of a customers DIY shed roof using sedums to soften the view for everyone
the possibilities are endless, limited only by your imagination.
Governed by the simple rule that Sedums are survivors and suffer only when really dry …at least you get an extra chance to add a little water to your extreme planting …you’ll be surprised to see them bounce back up with a little drink
Sedums and Hylotelephiums are perfect plants for pollinators.
Wild bees and other pollinators are in decline. One way gardeners can help is by planting garden flowers that provide forage for a wide variety of pollinating insects.
Using scientific evidence, extensive experience and the records of gardeners and beekeepers, the RHS has selected a range of year-round flowering Plants for Pollinators to tackle the decline in pollinator numbers and Sedums always sit high on the list of useful plants.
SedumShack Sedums and Hylotelephiums are covered with flowers from Spring to Autumn …theres a plant for every month and a mixture is sure to keep these insects happy.
The RHS Perfect for Pollinators mark is only given to plants that support polinating insects such as Bees, Butterflies, Moths ,Hoverflies and many others that visit Sedum flowers to feed on their nectar or pollen.
BEE KEEPERS love Sedums, planting them close to their hives.
When Honey production is at its maximum – late Summer – the Sedums and Hylotelephiums provide a feast…
Sedums to grow in your UK garden must be hardy to resist cold frost ,
and be tough enough to live through both wet and dry conditions.
The location for a garden sedum is well drained and bright light – at least a few hours of direct light each day, though this is not too essential for the deciduous sedums over winter so if the sun doesnt rise high enough to shine on these then its no problem – it may in summer when they need the sun, when the arc of the sun is much higher and your garden is lit much better.
These Succulents dislike constant damp and need to dry out regularly –
ideal for containers, baskets, troughs, wall and green roof gardens where water is sometimes added.
Hylotelephiums need Vernalising – 6 weeks of cold – to produce
short, compact growth and many good flowers the following Summer and Autumn.
Live-Forever Stonecrop Succulents they may be – it’s surprising how much cold, wet and miserable weather they can tolerate over cold Winters. Their Succulence and the way they function (CAM) is an advantage during drought and also over extended periods of cold and frost. Most other plants suffer terribly if they cannot ‘breathe’ for 3 or 4 months….but sedums seem to wake up each spring like hibernating Bears looking like they needed their long sleep – emerging with vigour and zest and soon growing lush leaves and filling their spaces before Summer flowering.
This is a trait of most Alpine plants and one that sorts out many other plants when it comes to surviving cold, wet frosty winters.
If you look closely at a succulent sedum when it is frozen it seems surprising that they will recover – but they do, and it seems they change slightly after this frosty period. The stems seem to stiffen and toughen, the leaves seem to rebuild their cells bigger and stronger and thicker ….so treat them to a frosty period if they are sheltered all winter. This temperature drop changes the chemistry and hormones inside the sedums – so to get the best flowering , and compact growth ….dont grow them in a polytunnel (like most commercial growers do …hint, hint …quality cannot be attained there)
To Care for these Sedums keep slugs and snails away from them, keep away from damp places, don’t plant them under other larger plants in your garden and always ensure they get at least a few hours of direct sunshine each day – preferably south facing (and never north facing).
Tidy leaves and debris away from them, and try not to damage them – that includes cats, dogs and footballs, although the smaller leaved groundcovering types can take the odd knock.
Good drainage is essential wherever they are planted – what falls from the sky is usually ample for a Sedum.
What Sedums excel at is surviving the dessicating, destructive effects of icy wind. Their leaf stomata close, their leaves and stems thicken and toughen and normal plant functions are stopped ….for many weeks, often months. They has a special adaptation, unique to this family of Crassula succulents (which includes Sedums) called CAM – Crassulacean Acid Metabolism< heres a link to WIKI about this …do please return here…!
Sedumshack Sedums and Hylotelephiums are great rock gravel alpine basket trough container gutter and roof plants – they can survive extreme conditions and are long lasting perennial succulents to grow in gardens that get very cold each winter – we do not sell half-hardy plants raised in laboratories and polytunnels ….that would be lying to you about whether they will survive ….please take your chances elsewhere with the other big nurseries who care not about this lie – nor have they ever tested their product in an English Winter outside of their plastic-clad nursery designed to protect these ‘chancers’ from inclement weather. That doesnt seem right to me, hence SedumShack doesnt sell many Sedums found in the garden Centres nowadays. For example one called S.Makinoi ‘OGON’ is often sold elsewhere as an indoor evergreen houseplant – yet Dobies and others think this can get through a cold winter. Hahahahahahahahaahahaha.
Ill leave that little chunk of humour with you……..dont be fooled by the shiney labels, trust on the Specialists….

Autumn-Winter Care of Sedums
Low growing, evergreen , groundcover Sedums only need light pruning (cutting back) if they have outgrown their space.
Plan ahead and remove a little more than needed to start next year tidy and ready to flower…these often form at the Stem ends so this ‘maintenance’ is recommended for better flowering and growth next year.
The cold temperatures will halt growth and the short days will delay flowering so little will happen until Springtime …enjoy these plants for their changing colours over the dull dark days.
Hylotelephiums – our SPLASH Sedums and our SUPERSTAR Sedums will now have halted growth and flowering. Colours will be fading and stems may be flopping. Tidy up, but leave some healthy stems in place…
They will eventually recede back to ground-level rosettes but for protection it is best to leave these through winter – they are attractive coated with frost and serve to protect the crown from physical damage until Spring.
Sedums are tough , and most can survive a cold, long winter of frosts and snow …but recent introductions to your garden may fail to reappear. Newer plants, especially the hybrids, are not Garden tested and may be fussy unless given perfect growing conditions.
Come back next month to discover the Perfect conditions to grow sedums in…
