Help! I'm Trying to Identify What Flower This is to Use in My Wedding Bouquet!

Any green thumbs or floral experts out there? I pinned this image a long, long time ago because it is exactly what I want my bouquet to be. I know the pinks ones are peonies, but does anyone know what the little green ones are?

Could they be baby's breath dyed green?

I thought maybe they were viburnum but the clumps look too small to be viburnum. Any ideas?
Anyway, it's dreary and damp in Maryland, so here are more gorgeous flowers to brighten up your Friday!
How stunning is this?
