How to Care for a Shooting Star Hydrangea | eHow. Not the best photo.. My "Hanabi" Shooting Star Hydrangea has bright pale green leaves. The lace-cap flowers are chartreuse, and the bigger "shooting star" blossoms sit 4-6" above the lace-cap and are white, aging to faint green. Blooms on previous year's growth! Don't dead-head as the old blooms protect new buds from freezing over winter.
