Invincibelle Ruby smooth hydrangea is truly a gem of a plant - you'll see that the moment you see its first bloom in summer. The tops of the petals are pink, and the lower surfaces a deep red-pink, a combination that brings to mind the exact tones of this precious gemstone. It's quite a heavy bloomer, so you'll have plenty of beautiful fresh flowers to enjoy and ponder whether the florets are more red or pink. You'll also find very strong stems, which keep the flowers upright, and dark green foliage for a dash of extra good looks.
