Hi all. I have 2 metal obelisk and I quite fancy putting climbers in the pot. The obelisk stands about 5ft tall. I quite fancy clematis as they are so showy but worried about the length of flowering time and pruning. If anyone can suggest 2 colours/ varieties. I'm looking for something that may be evergreen and long showy flowering season without having to have too much over winter care.

i saw some stunning clematis today and walked away in favour of asking everyone here, how I managed it I will never know. Thanks in advance

The evergreen clems tend to flower in winter or early spring and then look dull the rest of the year so need to be planted as a backdrop to other plants that carry on the display the rest of the year.

Clematis are hungry and thirsty plants with lots of thick, fleshy roots so your pots will need to be deep enought to let their roots grow and have access to plenty of food and water which will mean frequent waterings and feeding over the growing season.

Have a look at this site and research flower colours, flowering periods and also a suitable height for your obelisks.  http://www.clematis.hull.ac.uk/new-clemlistsearch.cfm

montanias do well  on climbing on things like obelisk.

Montanas are beautiful for a couple of weeks in spring but tend to need a whole house or lots of trellis or a long pergola as they are so vigorous.   There are smaller clems with a longer flowering period that will be far better suited to obelisks.

thanks. The clematis ranged from 6.99-23 pounds yesterday so I need to get it right. Am I too late to plant??

No.  Just make sure you get the planting soil and depth right and keep them watered and fed regularly.   Never let them dry out but don't let them sit in a puddle either.   Expect them to take a year or so to settle in and start really performing well.

..you might like the dark blue Clematis 'Arabella'... it's herbaceous so grows up vigorously from the base each season...so pruning is easy, just cut it all off.. I have this planted in the ground with an obelisk on top... it's one of the longest flowering Clematis there are, so I believe... some might find it a bit dark, and the flowers on the small side.....it's also a bit short..maybe 4 - 5 foot...there are taller types... have a look and see what you think...

My Arabella is lilac/mauve and is supposed to get to 2 metres - http://www.clematis.hull.ac.uk/new-clemdetail.cfm?dbkey=110 but I find that with each successive year it gts a bit bigger and produces more and more flowering stems that sprawl about as it is not self clinging.  I love it and it does flower for a long time.   It's also very hardy and copes with seriously cold winters.  Mine is planted in good soil in a hot, sunny bed and scrambles happily through a purple leaved cotinus.

Like the look of the Arabella but worry as it states non clingy, won't I have problems getting it to furl around my metal obelisk. I do fancy the type I have to prune right back as I don't like dead twiggy look over winter. I have tried looking at the link given but my iPhone struggles to load the searches

Red - they have bred clematis specially for pots too - think they are called patio clematis or boulevard series.  I have just used Taylors Clematis mail order and was delighted.  Really big plants for £8-10.  Very friendly people too - i'm sure they would be happy to advise if you gave them a ring

22/04/2014 at 22:53

..what I do is, I keep the canes in the middle of the Clematis so I can loosely tie in wayward shoots, [it doesn't twine or cling]...and I also push any shoots that want to grow outside the obelisk, in towards the middle, until they reach a higher point near the top.. then I allow some stems lower down to grow outside the obelisk.. this results in a cascading effect at flowering time... as some of the stems might flop which can put a dent in them, but this doesn't seem to affect the flowering... just carries on...

..incidentally...my growing conditions are quite different from obelixx above.... mine is growing in shade of north facing wall.. never gets the sun.. but is in good moist soil...  I underplant with Geranium 'Cambridge'...  as with all clematis I watch out for snails at this time of year....

22/04/2014 at 22:57

..just a caution about those Boulevard clematis chicky has mentioned above... my only  experience of these was one called 'Ice Blue'.. cost me £18... and it was killed by frost after 2 years... killed outright...roots were dead....we did have a bad winter then...  so if you see that one... choose another...

I have an Abilene that is about 4 years old - so has come through some harsh frosts.

22/04/2014 at 23:40

Love the look of Abilene but worry it states a couple of seasons to get going. Is there anything for impact this summer that's frost hardy. I do love the crossing petals more than the gappy petals but don't mind. i prefer larger flowers as I think on a small obelisk 4-5ft that will have largest impact. How fussy am I sounding!!

..they do look nice and would be suitable for your obelisk...and container... 'Rebecca' is one I keep admiring... I might try again with another at some point...

I have a north facing wall that I would like to grow something against, the problem is the soil is full of builders rubbish. How big an area would I need to clear out around the roots. The soil when I find some seems to be a good loam.

23/04/2014 at 00:57

..a common complaint...but it can be dealt with quite easily.... if you can manage to excavate a planting hole at least 12 inches square, 18 is better... then you should be able to get a container grown plant in there...get it off to a good start and the roots will find their way through any rubble...  one quarter of my garden has this problem but like yours, with a good loam underneath... you just need to help the plants get to that loam...

I have 2 clematis growing on my back wall, north facing and planted in a mix of rubble from when it was a farm and builder's rubble from our renovations.  I dug out a big hole as Salino advises but for two of them I also made a raised bed by making a square U with roofing beams and filling it with good garden compost mixed with some potting compost.    

This gives the extra depth and fertility the clematis need and also supports a Falstaff rose.  I've planted spring daffs and alliums plus hardy geraniums in one and hosta Fire on Ice in another and mulched the whole lot with chipped bark.  These were done late autumn 2012 and all the plants are very happy.  The clems are a Minuet and a Caerulea Luxurians.

..nice bit of flair and innovation there obelixx..just goes to show what you can do...

..and all on a north wall...I like that very much...

23/04/2014 at 13:59

Thanks.  It is a north wall with plenty of light as there are no neighbouring buildings or trees and it gets some sun after 3:30 between the equinoxes.  However it also suffers from brutal winds and severe frosts down to -32C in Jan 2009 but normally -20C in an average winter.   This mild winter we've just had means all the plants in there are very happy and about a month ahead of usual schedule.
