Clematis...

I don't see why not. I've got a few different types on the same fence myself.

 

Hi,

Those Suttons ones look good though they say they do not despatch until August and then only in a small 7cm pots, so you will be looking well into next year before they cover anything of that big fence, let alone flower.

Think you will find your local garden centers will have a much better selection now or shortly, ours usually have 1mtr tall ones in for under a tenner.

Guessing your fence is about 8-10 mtrs long ? so think you can get way will quiet a few plants, and have a look as getting group1 ,2 and 3 types and hardy ones so you have a good succession of flowers and foliage
One or two Montanas wil soon help cover the fence but they are mostly a spring flowerer.

Also consider some filler plants for the first season or two like tall sweet peas and other similar annual climbers like Nastrurtiums etc.

Places like the Range and B&M also have some limited varieties of decent sized Clematis plants plus lots of cheaper smaller ones that if planted early this year will be a good size next year.

 

Hi FC, if you're wanting a selection for all-year round colour, how about these...C. montana 'Mayleen' or 'Tetrarose' (spring), C. Perle d'Azur or Prince Charles or Blue Angel (early summer), C. viticella - any colour that you like (late summer), C. cirrhosa 'Winter Parasol' in the sunniest, most sheltered spot. I'd have recommended Taylors Clematis as having the best selection and good prices, but they've been taken over by Sarah Raven, so don't know if they're still feasible.

Thorncroft were good, too, if a bit pricey.

Or as Ricky says, have a look for some bigger plants in the local GC. Small plants can take quite a while to settle in to less-than-perfect soil. They'll need watering through their first couple of summers too.

 

Hi @Fat Controller when Morrisons start selling plants again (normally in March I think), they often have loads of different clematis very cheap. I got c. triternata rubromarginata and a couple of others - about £1.50 each I think. I recommend that variety

 

They are a bit to small they really need growing on another year, slugs like young clematis . How large / long is the fence FC? Clematis montana can get very large.

I like Montana but they can look messy in the winter , clematis Armandii may be of interest spring flowering evergreen / vigorous / scented and usually found at B&M for £10-12 . I bought a clematis Montana rubens from asda last year its ready to plant out now , its going on a fence.

And as Noisette has mentioned any viticella are brilliant plants and lots to pick from and usually much longer flowering around 3 months. I wouldn't be without my Super nova .

They is also some summer/ autumn flowering ones they are Flammula group some are very big like Terniflora ( probably not montana size ) white flowers and rubromarginata is another , they are the most scented clematis with small flowers but loads of them.

 

A good looking selection there

Don't forget to plant them deep as they say it helps regrowth if any suffer from wilt.

Some tall Sweet Peas will help fill out the fence during the early years.

ps just to add to @noisette47 comment about slugs, find a ring of the Copper Tape on the soil around the base of the plant really works when the new shoots emerge in the Spring,

 

Wonderful, FC! It's recommended to put the large-flowered, stripy pink and red ones in a shady spot so they don't fade in the hot sun..... Also to put a large flat stone or bit of slab on the soil in front of the plant, to help keep the roots cool. Watch out for slugs and snails, though
If you can, mix a bit of blood, fish and bone, or even just bonemeal into the soil, as long as the pooch can't get to it.

 

Well blow me, that must be why the pikeys round here have been known to relieve Orange of some of their wiring
Bless, they were just looking to protect plants...
