Lovely climber/s to cover a large shed roof?

[Pannacotta]

I need to get some greenery over my shed roof which is large and not very pretty.
The shed is next to the compost and has windows at the front so I cant plant anything too thorny or wild.
I know Clematis montana is often suggested but the flowering period is a bit short and I already have two in the garden. Same with Clematis armandii.
I could go for a rose but would need a thornless one which rules out the ramblers I think?
Any other thoughts?
Thanks

Oh - I spotted the perfect rose for you just the other day: fragrant, climbing, repeat flowering and thornless - it was called Zephirine Drouhin. I can't work out how to post a photo from my phone but I'm sure if you google it. Very pretty compact flowers in a strong pink.

Otherwise how about tracheospermum jasminoides (sp?) glossy evergreen leaves and highly fragrant jasmine type flowers in summer. There seem to be variegated version and even pink flowering ones around these days if you aren't inspired by the usual one.

Thanks Wild, I have had that rose before and my soil wasn't good enough (its quite light) and it got lots of diseases. Shame as its lovely.
I would need a tough old rambler, not too compact either as the shed is big and tall.
And yes I could combine with Trachelospermum for scent, nice idea.

rambling rector?

Could you have several to intertwine? A passionflower e.g. Passiflora caerulea plus a vine e.g. vitas coignetiae or maybe a honeysuckle e.g. lonicera americana or perhaps a jasmine e.g. Jasminum polyanthum

Akebia Quinata. Doesn't lose it's leaves in winter neither.

Yes I could plant several.
I love Akebia but don't find it covers very well as its very twining.
Will look up R Rector but have a feeling it is quite bushy.
A large leaved vine would be good.

Garrya Elliptica? Hydrangea petiolaris?

Does it need to be a climber? How about putting on a green roof, with sedums and so on? I find sheds with a green roof really lovely.

Like this

We have honeysuckle and summer flowering jasmine all over our shed.

Also have Paul's Himalayan Musk all over a fence. It's very prolific and absolutely stunning. It's romping way here and we have shit soil.

Wd love a green roof but don't have the budget.
Pauls Himalayan Musk would look good, how are the thorns?

I did my green roof for not much more than the cost of a climber. Just need some woods to retain the soil, a few cuttings of sedum and some soil and puzzolane. Sedums really do grow from every scrap of cutting.

Yes, I came on to suggest a green roof.

Thanks but my shed roof is as big as a garage and has a steep pitch so not feasible to create or maintain.

Some types of honeysuckle might do the trick for you OP.

Never grown them but would a Golden Hop work? Maybe a combo of clematis montana and a honeysuckle and/or Golden Hop?

Paul's Himalayan musk has thorns but not loads. It is THE most beautiful thing.

Quite keen on a lovely rambling rose and think Pauls Him Musk does look gorgeous, might try that with another climber or two, perhaps an evergreen honeysuckle and a gorgeous clematis I have discovered, Royal Velours.

I'd go for honeysuckle- fab scent and flowers

Honeysuckle Halliana is an evergreen so will work as a screen all winter too but, for me the Rambling Rector Rose I have growing over the outside bog is a treat to behold and flowers from May until October. The scent is divine (the rose not the bog, that was decommissioned in 1996) and I heartily recommend it.

Wow May till October would be great. That is unusually long flowering for a rambler!
Sounds ideal, really like the flowers too. How are the thorns though?!
