If it's a September wedding how about hydrangea - the coloured ones start to get that lovely faded look with burgundy and green shades coming through. Great with Illusion roses. What about poppy seed heads and firework grass. Sedum is great too - the green/pink one is lovely with Illusion, the brown one would be nice with Sweet Avalanche and Pepita spray roses.

Can you still get Metallica? My main dutchman told me last year that there were no growers anymore, though you do still see it in wedding flowers magazines.
