I have always wanted to do a wedding with lavender, not just the color itself but the actual flower. Lavender is a short lived annual or a herbaceous perennial. The smell is intoxicating and reminds me of freshly washed sheets.
There are many farmers who specialize in growing lavender: Prairie Lavender Farm, Woody Creek Lavender Farm, and Country Lavender Farm. Check out your local market for specialty soaps, blooms, plants, and many other products made from lavender.
Here is a little inspiration just for you. My favorite is the lavender wedding rice, much more eco-friendly than the bird exploding rice I should say.
