They're the type of flowers which are happy to look beautiful by themselves or when placed alongside other blooms.
A sunflower motif is effective on your wedding invites, seating plans, not to mention, you can put a packet of sunflower seeds by every place setting like a memorable favor.
If you're using a summer big day then consider putting your bridesmaid dresses in sunflower yellows.
Or you may also use the sunflowers along with other hues to produce quite a different feel for your day. Take a look below in a few of the real wedding color combinations.
Blue and yellow always interact well - so maybe that's something to consider for the rose gold bridesmaid dresses.
I love this bride's selection of delphinium blue and white flowers combined with her sunflowers, using the bridesmaids in pretty royal blue. Many thanks to Boho Weddings with this great shot.
And then for any different look - sunflowers combined with coral pink or red! Both of these combinations are stunning. Immediately below is definitely an inspirational look from Rustic Wedding Chic and below that's a riot of color from Jennifer Wilson, via Pinterest.
