Green Light Go reaches 28 inches (71 cm) and offers graceful 7-inch (17 cm) blooms, producing about 26 buds on five well-branched scapes. An early-early season, semi-evergreen tetraploid with reliable rebloom and a gentle fragrance, it displays white petals heavily overlaid with green (up to 90 percent), giving the flower a soft, two-tone glow. The petals are deeply piecrust ruffled in green and subtly diamond-dusted, all above a rich, deep olive-green throat. With parentage from Certainly Green and Whirling White, Green Light Go brings refined coloration, sculpted texture, and strong garden presence.
