There is a new Annabelle cousin that is currently out for sale (I was not aware either). More compact and a shade of pink different than the others. Check local places that typically sell Proven Winner Hydrangeas (to see if they ordered it). From the wholesaler:
Hydrangea Invincibelle Mini Mauvette is the very long name of this 2.5'-3' tall to 3-4' wide small version of Invincibelle, which is in turn a "cousin" of Annabelle. Details from the wholesaler: "A whole new color for smooth hydrangeas! 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."
