 'Annabelle' is a naturally occurring cultivar that was discovered ~1910 in the wild near Anna, (Southern) Illinois. Plantsman J.C.McDaniels from the University of Illinois named it and promoted it for its extremely large flowers (corymbs) which are considerably larger than the species. It is probably the most grown cultivar of smooth hydrangea. It blooms on new wood, so it is quite hardy. It can be cut to the ground in late winter to promote plant vigor.

The 'Annabelle' Hydrangea is a very common shrub planted in the average yard and in professional landscapes, offered by most all conventional nurseries and big box stores in much of the USA. This cultivar has rounded flower heads of all or almost all sterile showy florets, called a hortensia or mophead flower cluster, not really good for pollinators. The flower clusters get to about 12 inches across. It has replaced the old-fashioned 'Grandiflora' or 'Hills of Snow' Hydrangea that has smaller flower heads. The heavy flower heads fall down a lot. The flowers turn from white to light green later in summer before turning brown in late summer through winter. It is best to cut it to the ground in early spring for a better-looking plant that blooms on new wood, that is barely wood for many hydrangeas.
