Luckily, my spring wedding is right smack-dab in the middle of peony season. Yay! However, they are quite expensive. So maybe I'll have a few in my bridal bouquet and get a similar look by substituting garden roses elsewhere.
Overall, I think the floral theme will be fluffy and romantic with a just picked garden-y/wildflower look. Did wedding planning open your eyes to different kinds of flowers? I've lucked out, but did you end up falling in love with flowers that won't be in season for your wedding?
