Wildflowers are lovely in a wedding bouquet for a country summer wedding. Daylilies and roses along with snapdragons, purple coneflowers and dwarf sunflowers make a sweet bouquet. The challenge with incorporating daylilies into a bouquet is the blooms only last a day. You will have to find your own source, either your own backyard or a neighbor's garden, because daylilies are not available through florists, grocery floral departments or online as a cut flower. Assemble the bouquets without the daylilies and add them at the last minute.
Cut 1 inch off the stems of the roses a well as the other flowers, but not the daylilies, and plunge into ice water for at least one hour before arranging into a bouquet.
Remove any bruised or damaged petals and all of the thorns from the stems. Cut the thorns with a paring knife or snap them off with your thumb and forefinger.
Fill a vase that's no more than 8 inches high with ice water. Cut the stems of the roses to 10 inches long and put them in the vase. Cut the stems of the snapdragons so the flowers stand above the roses by 6 to 8 inches. How much you cut depends on how long the stems are to begin with and how much of the stems are covered in flowers.
Cut the other assorted wildflowers, but not the lilies, to 10 inches long.
Put the roses in the vase, allowing them to fan out. Place the snapdragons among the roses. Fill in with the other flowers.
Place the flowers in a cool, dark place. If there isn't room in the fridge, fill a cooler with a few inches of ice and use that. They should stay fresh for several days if you refill the ice. Misting with water helps, too.
Cut the lilies the day of the wedding. Daylilies are large flowers so you probably won't need more than three to five (odd numbers look better in a bouquet) per bouquet. The stems should be cut so the lilies are at the same level in the vase as the roses. Place them in the vases.
Remove the bouquet from the vase. Place rubber bands around the middle of the stems 2 inches apart. Cover the rubber bands with ribbon wrapped around the stems. Replace in the vase until it's time for the wedding.
