Invincibelle Wee White ® hydrangea is poised to revolutionize landscaping. Its sturdy compact frame reaches just 1-2.5' tall and is covered in pure white mophead flowers from summer to fall. We'd call it a dwarf version of 'Annabelle,' but that wouldn't quite do it justice, as it also boasts very sturdy stems that never flop and the ability to rebloom, producing fresh flowers all summer.
