I like ivory and green bouquets with loads of texture.
(All photos except top row, center, from The Knot. Top row, center photo is Ariella Chezar, from Elise Theuer.)
On the other hand, I also love single-flower bouquets and non-floral elements.
Top row: bouquet of berries, from Martha Stewart; Amaryllis, from the Knot; Icelandic Poppies, from Martha Stewart; roses & celosia
Bottom row: Baby's Breath from Martha Stewart; pheasant feathers and roses from the Knot, roses and thistle from The Knot, coordinating bouquets
Pictures I've liked and never put them in a board:

I love this gold wrap for my bouquet!
Boutonnieres aren't a huge priority, but Mr. Limey would like a red rose. I'm not a huge fan of red roses, but I'll oblige him this one request! I'd still like it to be cool, though. I like the wrapped calla lilly (top left) and the extra ornaments on the ones along the bottom. The white rose? I like that it's small, and not a huge prom-sized flower.
Gorgeous ideas:
