Compared to its famous sibling Limelight, Little Lime hardy hydrangea (Hydrangea paniculata) may seem like a pipsqueak. Don't let this petite shrub fool you. While maintaining its short stature of 3 ft. to 5 ft. tall and wide, it really packs a visual punch in the garden. in summer, lime green blooms open on strong stems - no drooping here. As it ages, rich pink coloring emerges to prolong the show through fall. Little Lime hydrangea is small enough to grow in containers and also stands out as a bold mass planting. Its bright bloom coloration makes it an excellent choice for cut flower gardens and can be used fresh or dried. This reliable performer blooms on new wood, so a quick trim in late winter or early spring will encourage fresh growth and an abundance of buds. Like most hardy hydrangeas, it is hardy to Zone 3 and does best in full sun or part shade. Summer flowers open soft green and turn pink and burgundy in fall.
