I heard something on GQT on R4 on Sunday saying that sedum was difficult to
get, and all you got nowadays was some inferior variety.

Is this true?

I have told someone that I would kindly build them a green roof on their
garage, idiot that I be. I haven't a clue what I'm doing, but I was going
to put a rubbery membrane on it, build round the sides a bit, fill it with
compost and plant sedum and maybe some alpines etc, in a Norwegian stylee.

You can't walk on the roof, it's asbestos or similar, so I can't be
weeding it either. I understand that I can put chicken wire over the top
which stops certain wildlife eating the roof, but I think that would be
ugly in the extreme.

Any ideas/tips/pointers/books/articles on the subject would be very
welcome.

Thank you

I think your problem will be the weight loading,particularly on something
like an old and brittle substructure.
These people tell you more about how it should be done and loadings.
