Today marks National Best Friends Day if trending Twitter hashtags are any reliable indication of special occasions (with over 7000 tweets attributed to this hashtag we're going to give it some credibility). If you want to pay tribute to your own best friend by sending flowers to express friendship and platonic love, we would recommend a bouquet of yellow roses as the perfect choice. Yellow roses are symbolic of friendship, managing to avoid the more passionate romantic connotations of red or pink roses.
If you have a friend who you'd maybe like to be more than friends with, sending a bouquet of orange roses can be a great way to suggest ambiguity and desire. Whilst not as strong as red or pink roses, there is undeniably some romantic association with orange roses without going overboard and risking the friendship!
