Can you name this painting?

I saw an amazing painting in the Albertina Gallery in Vienna last August and I can't remember the title or artist.

It's a night/evening scene an on the right you can see a city in the distance. On the left there's a person lying on a hill and above them a giant bouquet of flowers.

I suppose it could be described as surrealist and there might have been other images in the sky, sorry my memory's a little vague!
