Smooth hydrangeas are beloved for their big, reliable, blooms. But color has never been their strong suit - until now. Invincibelle Mini Mauvette ® hydrangea brings a never-before-seen color to the species, with large mophead flowers in a deep mauve-violet. Blooms are held on very strong stems and appear early summer through fall. Dwarf habit gives this native plant amazing versatility in the landscape and the garden.
