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 3-5’ 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.
