A garden wedding needs a garden venue. Walled city gardens, greenhouses, overgrown farms, all of these can set the scene for your natural affair. From there, it isn't too hard to convey the theme: keep your colors neutral with browns, greens, yellows, and other earthy hues. Wedding favors, like wildflower seeds or little planters are a cute personal touch. When choosing a bouquet, look for cascading greens to enhance the garden look.
