The Annabelle Hydrangea (Hydrangea arborescens Annabelle) is the perfect choice for those who live in climates too cold for the commoner Hydrangea macrpophylla cultivars. The species type is native to North America, and this heritage cultivar has absolutely massive blooms up to 12 inches across. Because it's a quick grower that likes to be cut back in winter, many choose it as a stunning hedge plant. It's happiest in light shade, but it isn't too fussy about getting sunshine either, making it an adaptable and easy to grow and spectacular option.
