I have a special place in my heart for any flower that is green and white! So snowball viburnum hits the mark. The name accurately describes the flower–a snowball. These lovely green and white balls of blooms tuck nicely into spring arrangements and are easier to work with than large, heavy-headed hydrangeas. (If you love hydrangeas, you’ll LOVE these!). Harvest these while the flower is still green. If it wilts at any time in the vase, clip the stem, dip in boiling water, then place in cool water in the refrigerator until the flower rehydrates.
