Creating a green roof for a small shed in shade
Hello! I am a newbie to anything more adventurous than moving the lawn. I would like to create a green roof on a shed which I look out on from the kitchen sink. But it is totally in the shade and never gets the sun. Has anyone got any experience of what might survive in a cold shady Scottish corner?!
Many thanks!
Alison

You will need to make a box frame to take a depth of soil, membrane and drainage.
Can you post a photo from you kitchen?
However, if you manage it, some of the saxifrages will grow in shade - Saxifraga urbium [London Pride] will grow anywhere, and small ferns will also grow in almost any conditions. It would be a question of finding the right ones.
I have a white saxifrage that grows in a fair bit of shade too, as well as lots of other places.
Even some of the smaller Heucheras would grow - it's surprising how little they will grow in, as long as they're damp enough. I had a piece of Lime Marmalade which was stuck in a pot for weeks - no soil, just wet from the rain. Looks great!
You may need to limit it to a few varieties of plants
If you can open your kitchen window enough you can water from above or use a spray lance on a hose pipe and a set of steps at ground level.
Would a moss roof potentially weigh less as requires less soil etc? And could you intersperse it with the ferns/other plants suggested by Fairygirl?
Many thanks again Alison
To be honest - I hadn't thought of a moss roof, but that would be lovely, and would be lighter. A moss covered wall, for example, is a real delight.
Easy to do, easy to maintain - and moss just grows here anyway - as you probably know already
I also have a few polypodium ferns in the shadiest section, but I think the depth isn't good enough for them as they've struggled a bit.
For comparison, my green roof is about 15cm deep, on a 20 degree slope and the right hand side is in full shade all year. The left hand side gets sun in the afternoons in late spring / summer.

I hope that helps! This is one of my favourite parts of the garden and seeing a bit of green makes the world of difference when washing up.
