Indoor climber

30 mm, or 30 cm, Tradingsites? Also, can the room be ventilated in summer?

Hmm, next to impossible - but what are you intending to plant in, including the size of any container (depth, height and width)?

Cissus antarctica – Kangaroo Vine is a good indoor climbing plant. It tolerates shade and cool temperatures.
However, a 30mm trough sounds rather shallow.

My ma had a Stefanotis which was growing in a medium sized pot growing round an indside door frame and the flowers were extremely fragrant. Lovely plant.

I had to laugh, Hywel, talk about the understatement of the year - if the asker really means 30mm and not 30cm, three centimetres is not something you can plant in... 30 cm though, that's a little bit better, but depends whether thats 30 cm deep and what the width is as to whether its enough to grow a large climber.

That's true :)

I was thinking possibly Algerian Ivy (Hedera canariensis), since I don't know how cold it gets in there.

Many Hedera would do, given proper root room, Tug, but, and its a big but, all will root into the wall rather than 'climbing' up a trellis...

Oof! how could I forget that! Maybe Star Jasmine (Trachelospermum jasminoides), then, though that could be pretty overpowering indoors. Hmmm...gotta think....

He said its shady, or at least, indoors with no sun, that knocks out star jasmine too, I'd have thought... he'd probably be better off growing bamboo in pots, at least it grows up straight...

Star Jasmine grows and blooms with no direct sun here, though reduced bloom might be no bad thing, indoors. Admitted, the light intensity might be greater here, on average, even with no direct sun. I figured that it should be fairly bright in there, since it has so much glass. Maybe Asparagus asparagoides, or A. falcatus? Depends on the temps not dropping below -2º C, though.

Thank you for the help. Sorry, the concrete walled container is approximately 450mm high and about 2m long and 300mm wide. I will fill the container with soil and compost left over from a wildflower substrate I have used on the houses roof. It has drainage holes and an automatic watering system. The area is protected from frost and will get good light (but no direct sun) in the early mornings and summer. The area also has air movement via a thermostatic controlled fan that draws air in from trickle vents from within the window frames. I am only wishing to grow the plant to a height of about 10ft. I hope this helps!

Well I suppose you could try Trachelospermum jasminoides - if you do, though, mesh flat against the wall isn't an ideal support, it would be better to use proper trellis, fixed onto battens, to leave room between the trellis and the wall for the plant to twine around the trellis. In the UK, though, Trachelospermum flowers much better with some sun, so I can't say how well it will do, but at least its evergreen. Bear in mind, though, that evergreen plants do drop leaves - they do it year round rather than dropping them all at once like deciduous plants do, so you'll be in for a fair bit of clearing up probably weekly.

Your other option is not to use a climber at all, but a bamboo - Chimonobambusa marmorea, in the ground, gets 2m tall, but may not reach that contained in such a way. Whilst it likes some shade, I'm not sure how well it will do with no sunlight at all, but, apart from Fargesia sp., is more tolerant of shade than many. I haven't suggested Fargesia because they have a tendency to get to about 6 feet and then droop over at the top, which will block your narrow passageway. The same caveat regarding falling leaves applies...

Ah, thank you, Andrew! If there is no actual frost, there are a number of subtropical species that you could use. Stephanotis (as Cammomile says), Hoya, Syngonium, or Monstera deliciosa spring to mind, though you might need to keep pruning shears handy for wandering roots on that last. All can tolerate relatively low temps in the winter, though you may want to run an electric space heater occasionally in an extreme year, to keep the temp above -1º C.

You might like to consider plastic covered mesh made for the job rather than painted steel, and install it fixed t blocks so it stands a couple of inches away from the wall. You can only get it in black brown or green but it doesn't need painting ever whereas painted steel will eventually need it or will rust.
The pic doesn't show any provision for collecting drips from the drainage holes?
Acid loving plants are not always happy with their roots us against concrete so that's another point to take into consideration.

My gut feeling is that you are being a bit optimistic. A large plastic plant would avoid all the problems and would avoid any need for an expensive irrigation system, which honestly sounds like overkill to me for one plant. Plants need regular attention, especially in challenging positions, and attending to their daily needs gives you the chance to check any problems before they become severe. Just wondering whether a really good mural wouldn't suit your purposes better in that situation and save a lot of disappointment? You could then grow something really tolerant (eg a Swiss Cheese plant) in a container in the corner.

As the trough is there, Steragram, it makes sense to use it for something, even if that's just a row of Spider plants all the way along the wall - no height, but it'll look attractive, so long as it doesn't get too cold in winter.

Thank you for all your help. I would like to use the planter now that it is in. I did not explain that on the right hand side of the picture is a glass French door that opens into the master en suite. There is a tap by a chair that will link to irrigation pipes so will just need turning on. The drainage is in the concrete floor and linked to storm drainage and the floor will be covered with hard wood decking.
I will be able to tend the plants on a regular basis and will give me pleasure doing so! The glass on the roof has had to be about 24mm thick to support someone walking on it and I can also open the house doors to heat the space without loosing to mush heat. Also linked to a wood boiler it would help with RHI payments!
The picture is a little deceptive because there are to reveals on the right hand side enough to house a chair.
Thank you
Andrew

Sounds as though itsgong to be quite luxurious when its all done! Sorry about all my caveats, but they might have been helpful in other circumstances... Would love to see some photos when its finished!

Agree Bamboo, but he did say climbers specifically?

My experience with bamboos is that they don't do well indoors, anyway, though that may not apply to an unheated near conservatory. Bamboo Palm (Chamaedorea erumpens or C. seifrizii) may work better that way.

Thank you all for your help. I think that I will try bamboo and see how it works. However I am worried about it getting too wide and is it possible to control this by trimming and training?
Yes, the new house is a bit of a Grand Designs project and I have brought a small farm at Tiverton, Devon which I intend to turn into a nature reserve. Having retired from a large commercial farm in Hampshire, I will be installing many wildflower meadows, ponds and managing a 150 acre a ancient woodland that runs down to the river Exe. My aim is to see how diverse I can make my 300 acre patch of rural England from a standing start! I welcome all visitors and if passing would be delighted to show you around. I will try to put up some photos or upload to my website. There are other areas that are not conventional that I would welcome help with.

Bamboo is very trimmable, but, for best appearance, shouldn't be whacked at with hedge shears. If it were me, I would imagine a mental perimeter about 50 cm outside the trough. In the spring, as the new shoots grow outside the perimeter, selectively cut them back to side shoots, or at least a node, about 20-30 cm inside the perimeter. Side shoots will develop to make a full and natural surface near the perimeter. Height can be maintained the same way. The lowest and most slanted of the main shoots can be thinned out, to show off the other stems' distinctive form and color.

Ooh, nice part of the world, and sounds like a really interesting project you're starting, looking forward to ongoing updates, with photos preferably!

Sounds like a wonderful project, and an ideal part of the world to try it. Let me know if you want any primroses.
