Flower Explosion sells many different tints, tones, and shades of yellow flowers. Regardless of the types of yellow flowers you choose, they will bring happiness to any floral arrangement. Yellow color flowers can really be used any time but there are special times when the color yellow conveys that meaning of friendship. Consider sending a dozen yellow roses to a close friend during International Friendship Month, which is February, or to celebrate the Old Friends, New Friends Week during the third week in May. Lastly don’t forget Friendship Day, which occurs on the first Sunday in August. All of these little known holidays can be celebrated by creating a yellow themed tablescape, which could include a centerpiece made from yellow sunflowers and pompoms.
