Does anyone know how to accomplish the color of dusty ****** leaves?  Is there a tutorial for making them somewhere?

Do you mean like eucalyptus leaves? If so I made them by mixing apple and forest green until I had a lump of "sludgy" green paste( kind of shabby chic looking) and then dusting them with a little icing sugar mixed with grated blue chalk. I didn't steam them as they are supposed to be kind of matte. 

Yes they are kind of the same colour.  Apparently this site censored the word m i l l e r as in Dusty ******.

Thank you for the advice with how you make the colour.  I tried something last night and it was way off.

Dont dust all of the leaves if they are on a spray, they look more reaistic if the lower (older) leaves are dusty and the top (younger) leaves are fresher.

That's a good point.
