Hydrangea arborescens


hydrangea


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.

annabell

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.

Big leaf hydrangea

oak leaf

is the most popular hydrangea. Flowers open white in panicles up to 12 inches long and 4 inches wide. Individual flowers within the cluster are about 1 inch. The fragrant flowers are present in May and June. Flower color changes from white to pink with some purple then brown. Propagation of Hydrangea's is easily accomplished by taking cuttings or purchase your plants in containers at a local nursery.


Choosing a Hydrangea known to do well in your area and giving it the right requirements are extremely important to have a happy and healthy plant.

Bigleaf hydrangea should be pruned after flowering so they can develop "old wood" to support blossoms the following summer. Avoid pruning after August 1.

One of the easiest ways to propagate bigleaf hydrangea is by layering. This is done by digging a trench near the plant and bending a section of limb down into the trench. Use a knife to remove a small ring of outer bark about an inch wide all the way around the limb. Then, cover the limb with soil, leaving 6 to 12 inches of the tip growth uncovered. Old established hydrangeas may also be divided in the early spring by using a shovel to divide the clump.
