Hydrangea arborescens
and paniculata can grow well in full sun and may become leggy if grown in dense shade. However, both use large quantities of water when grown in full sun and should not be allowed to wilt. As a result, some growers produce these plants in light shade or in areas where plants will receive natural afternoon shade.

Annabelle is the best known variety of Hydrangea arborescens. Similiar to most other hydrangeas, they prefer morning sun and afternoon shade or dappled shade all day, especially in the south.
prune Annabelle to about 18"-24" tall rather than cutting it to the ground every year. This will allow the stems to thicken a little each year,and thus better able to support the other branches and blooms. In addition, the heads will be more plentiful but slightly smaller. This plant blooms on new wood and can be pruned back during fall/winter or anytime except during spring when it is preparing to bloom. In the heat of our summers even in partial shade most of these plants require extra water or they wilt in the afternoon heat.
