The Tulip is one of the most iconic and beloved spring flowers, instantly recognizable by its clean, cup- or bell-shaped bloom. Tulips grow from bulbs and are known for their bright, clear colors that come in nearly every shade. A unique and fascinating trait of cut tulips is that they continue to grow in the vase and are "phototropic," meaning they will bend and stretch towards the light. This gives any arrangement featuring them a dynamic, evolving quality, as they seem to "dance" and change position from day to day.
