Invincibelle Limettaź hydrangea is the easy way to experience refreshing summer color every year. It's as reliable as the classic 'Annabelle,' but offers big-time improvements, like strong stems that hold the blooms upright all season, and a dwarf, rounded habit that makes it perfect to plant anywhere, from foundations to flower gardens. In early summer, spheres of lime green flowers appear. They lighten to a soft green-white before turning jade green for the rest of the season. They last clear through frost for a persistent show that takes practically no effort on your part - they are great for both fresh and dried cut flowers.
