Ruby-red smooth hydrangea! The dark burgundy red flower buds of Invincibelle Ruby open to a two-toned combination of bright ruby red and silvery pink. The foliage is extra dark and stems are strong, making this new hydrangea a gem in any garden. It is a strong rebloomer that will be an excellent addition to any garden. Like other smooth hydrangeas, it flowers on new growth and so blooms every year without fail.
