But I have just found Neat Image... which does a great job at removing noise. Like it! With the demo version I have been able to control the noise in the shadow areas somewhat. This is what I got:

3. Used curves to brighten the photo.
4. Because the photo is basically monochrome, I used vibrance at +10 and saturation at +10 to put a little colour back.
5. Job done.
If you crank the brightness up to stupid levels (say, setting the middle point to 2.5 using Levels) you get enough of the bouquet of flowers visible to allow you to at least make out the leaves. Possibly you could this as a template and paint on some colour to this area. I've done something simple, copying this area to a new layer, giving it an opacity of 44%, and then used a soft brush to paint onto a layer mask to blend the edges a little better. You can see the extra noise in the flowers on my version. Not totally happy with it, but getting a little foreground interest into the photo seemed to improve it.
