This finish has produced a huge range of options for gardener , and there are now clematis with huge variations which suit a range of unlike condition .
“ Clematis is the most versatile genus I have intercourse , ” debate Ken Black .
“ By selecting variety from different groups , they will extend [ their ] cooking stove of colour and peak to any garden and put up flowers throughout the year , even in the depth of winter . ”
Clematis has become prized for its ability to sputter up wall , fences , treillage and other support complex body part , and many are well - get it on cosmetic plants .
The horticultural classification of clematis is a complicated affair .
But broadly , clematis is divided into small - bloom groups , and both early and late big - flowered group .

“ This is a genus that has variety produce to only a few column inch or monsters attaining 20 - 30 feet in a season , ” allege Fraser .
“ There is a clematis for all time of year and all situation . ”
The big - flowered group are super democratic in gardens .
These are mostly believed to be hybrid involve crosses ofC. lanuginosa , C. patensandC. viticella .
Common Varieties
“ There are so many clematis varieties that there ’s something for almost every office you could believe of in the garden , ” says Peter Skeggs - Gooch .
“ Their various nature and abundance of colours mean we have a deal of options when it comes to fulfilling our horticulture pauperization . ”
More than 80 different clematis form have gained the RHS Award of Garden Merit .
Here are some common varieties to look at which have get this honor :
“ The plant I could n’t live without would have to be my Clematis ‘ Wisley ’ , ” shares Janice Shipp , Garden Writer .
“ It ’s a sweetheart and every year I ’m astonished by how crowing it get and how many flowers it has . I can sit down on my shake bench and look up to it for week on end and I would really miss it if it was n’t there . ”
For those just starting out with produce clematis , Peter has some apt suggestions :
“ There is one group of clematis that are very absolvitory and splendid for tiro … ”
“ They are call the ‘ Viticella ’ and they are late summer flowering and very fertile in the quantity of flowers they raise , they also require less attention than many clematis because of their natural vigor .
Ken Black agrees :
“ Viticellas can be implant in a variety show of garden place and they come in many different specter , size and bod of blossom .
“ They are fairly disease immune and when firmly pruned each spring , down to about 3 feet , will supply an teemingness of peak . ”
“ Viticella grouping Clematis are a unfluctuating favourite of mine in the garden , ” says Horticulturist Colin Skelly .
“ The first Clematis I ever grow was ‘ Etoile violette ’ and it is still move strong despite being actuate a few clock time .
“ Once established , they are childlike to grow and prune and give plenty of floral rewards with minimum endeavour . ”
Planting Clematis
“ Clematis are often portrayed as all having the same habits and growing needs , but this is not true , ” says Ken Black .
“ They originate from many parts of the world mostly , though not entirely , from the northerly cerebral hemisphere .
“ Access to information about what conditions are best suited to each group is therefore authoritative if you want to get the good out of this wonderful range of plant . ”
Most Clematis will grow best in a cheery or partly shaded spotlight and will not flower as well in a deep shaded locating .
The approximation is usually to keep the radical coolheaded and moist , so a posture which allows for weak ghost at ground level but provides plenty of sun for the get plant is commonly ideal .
However , there are cultivar which can be chosen to suit any spot , be it a shady wall , or one that is particularly bright and sunny .
Herbaceous type usually want a berth in full sun , and some clematis , including wintertime and spring flowering type , ask a sheltered stance since they are not so hardy .
Of course , crampoon like clematis will take some variety of support , be it other plant life , a loose - bear trellis or other social organization , or a support structure on a rampart or fence .
It is important to think about how you will support your clematis before you decide where exactly to set it .
We ’ll discuss your options for supporting climbers like clematis a little later in this guide .
Many clematis also work well in containers .
The first phase in planting clematis is organize your planting area and supporting structures .
You involve to be aware of the growing requirements of your clematis ( covered below ) .
“ A adept depth is demand to fit a couple of forks full of rotted compost or manure and to allow the root chunk of the clematis to be embed about 2 - 3 inches deeper than the original level in its pot , ” explains Peter from Thorncroft Clematis .
Clematis is planted somewhat differently depend on what type you are mature .
enceinte - flowered types are planted with the top of the rootball 5 - 7.5 cm below the surface of the soil .
This can be beneficial in allowing the plant to reclaim if infected with clematis wilt and it encourages the growth of newfangled shoots from below ground storey .
Other clematis types are engraft with the top of the rootball only just below the surface of the land .
Whichever type of clematis you are planting , it is important to make certain , when plant close to a rampart or fence , that the planting hole is beyond the rainwater shadow of the structure , as Ken Black explains :
“ When planting a clematis to raise up a paries , do n’t plant it too close to the social system because the basis of the wall will be dry and the clematis will not find enough wet . Plant it at least 3 feet away . ”
If you are engraft clematis to mount a Sir Herbert Beerbohm Tree or shrub , it is beneficial to plant it on the side from which winds most oft come near .
That way , the climber ’s stems will be blow towards the trunk or subdivision rather than away from them .
Clematis should usually be placed at least 1.2 m aside from the al-Qaeda of the supporting plant life to debar excessive competition for nutrients and water .
When grow clematis in batch , remember to think about support and check that that if the financial support is in the container , the container is large and heavy enough that it will not be knocked or go down on over .
Any clematis containers should be at least 45 cm in depth and width .
engraft your clematis in the container with apeat - liberal , soil - based potting compost .
Ongoing Clematis Care
Clematis can allow a broad variety of soil and soil conditions , but they will tend to thrive most when planted in a thick , fertile , and moist but free - enfeeble soil or medium .
“ There are a lot of clematis form with fine root system , and they can be prone to ‘ wetting off ’ in the winter , ” explicate Peter .
“ Soil drainage can also be of import for sealed cultivars , so you should pay close-fitting attention to the root system when you take the sess off and , if the tooth root are very fine and fibrous , then free - drain conditions will be preferred . ”
If your soil is not optimum ( if it is with child clay , for deterrent example ) or very luminousness and sandy , bring plenty of organic matter prior to planting will assist afford in effect termination .
Clematis will vary in their idle requirement .
As mentioned above , some are better in sunlight and some in fond refinement , though flowering will always run to be diminished in mysterious tone .
As a world-wide rule of thumb , recall that it is usually best to keep the root in light specter and give up the plants to produce in full sun .
This is of import when growing in containers as well as growing in the ground , so add otherlow - growing companion plantsaround the al-Qaeda or add together mulch to keep the roots cool .
Clematis lean to be rather picky about soil wet and will abide if the soil or arise medium is allowed to dry out .
check that that you irrigate well , particularly during dry menses until plants are well established .
commend that clematis growing in containers will need to be water more often than those growing in the ground .
When water clematis , make trusted that you give the plant life a deep soaking .
The soil or growing medium should be exhaustively soaked to around 30 cm in depth .
For plants growing in the ground , this might typify at least four watering seat worth of water per straightforward time .
Thinking about how you will reap rain to meet watering needs is a very good idea when growing these thirsty plants .
Clematis motley in their temperature necessary as some are brave than others .
However , most clematis plants will appreciate a quick and sheltered daub , with relatively high humidness , especially around the base of the industrial plant .
Marcel from Floyd ’s Climber & Clematis think that create shade at the base of clematis ’ radical is one of the most important care factor , as this help to keep the roots cool .
Mulching is one way to do this .
A garden compost , well - waste manure , or leaf mould can be ideal , since these will not only keep root nerveless and avail maintain moisture but will also provide slow - firing nutrients to the plants .
In accession to add together constitutional mulch around the bag of the clematis for birthrate , it is also a in force estimate to tally a potassium - plenteous constitutional plant food around the base of operations of the plant in early spring each year to promote just unfolding , as Ken explains :
“ Feeding is optional , but the quality and bit of flower can be improve by providing additional nutrition . ”
Container - develop clematis should also be fed with a multi - purpose constituent liquid feed during the spring and summer around once a month .
Support is crucial for clematis plantsand pick out the right choice can aid you reach the best and most pleasing results .
There are many options which are both practical and aesthetically sympathetic .
For example , you might grow clematis :
Some go up clematis can twine naturally around their support , but it is a good thought to carefully tie in the stems to your accompaniment to make trusted they are secure and distribute out more equally over the social structure and heyday better .
utilise natural twine and secure the stems using a loose figure of eight knots .
Different character of clematis require dissimilar pruning aid , as Ken reminds us :
“ Each year I am invited to talk with garden order and one of the most vulgar result raised is pruning . This is not a difficult subject if you know the name of a clematis .
“ Too often , however , the plant label has been recede and the name is leave . ”
Vigorous growers and early - flowering species generally need no pruning at all , though occasionally tangled growth may need to be thinned or dispatch .
early on flowering large - flowered clematis case are generally pruned gently in the dormant period to ameliorate their bodily structure .
Late - blossom large - blossom clematis is also unremarkably pruned during the torpid catamenia , and the current season ’s growth is generally crop back to a pair of buds .
If you are timid about which pruning group your clematis fall into , you’re able to follow this simple rule : If clematis blossom before June , do not prune .
“ By remembering this , you are not going to cut off the bud of a clematis that is about to blossom early in the year and has shape its buds before becoming dormant for the wintertime , ” explains Ken .
“ Any clematis that should flower from June forward will still do so even if you might have been more heavy - handed than you need to have been . ”
If they bloom afterwards , prune in late winter ( I rule that February is the safe month to do so ) .
Clematis can be propagate from semi - advanced cuttings taken between spring and late summer .
In warm and humid conditions they should usually settle down within a mates of months .
These cutting should be pot up into individual pots the following outflow and should flower within two years .
Clematis with prospicient , flexible fore can also be propagated by layer ( looping stem below the soil to encourage novel root to forge on the buried section ) .
After 1 - 2 year , young roots should have formed and the stems can be discerp from the parent .
