As you know, we're singin' the blues in May, and one of my favourite ways to have a something blue at your wedding is via a blue bouquet. But blue bouquets are a funny thing - because there aren't that many blue blooms (compared to, say, pink or white), an-all blue arrangement can be a bit... overwhelming, or at least look a bit artificial. Which is why, even when they're planning a wedding with a blue palette, many brides choose to go with white or silvery flowers and foliage. But with the right flowers in season, and the right combinations and accessories (blue ribbons? love), it can be done - and these 20 incredible bouquets show just how beautifully so.
