That's actually kind of odd. All the weddings I've seen and heard about it was the wife who wanted to plan and have the ceremony and the guy just wanted the wedding for the wedding night. (Stereotypical I know, but still.....) Do have a color scheme yet? Start with that and go from there. You can find flowers in literally any color (especially fake ones which I would recommend due to cost). After that the tuxes for groom and groomsmen should match the flowers (though I would with a darker shade for the tuxes), white dress for you if that's what you want. Brides maids should make the men. After that as far I know it's little minor details. Though before I would definitely try to get your fiance involved and make him actually tell you what he'd like and find some form of compromise. Unless you've already booked the hall and sent invitations you can always push back the wedding to accommodate.
