Hydrangea arborescens ‘Hayes Starburst’

Hayes Starburst Hydrangea is a floral arranger’s dream. This chance discovery, by Hayes Jackson of Anniston, Alabama, differs from the species by its showy display of clustered greenish white, multi sepaled star shaped flowers. It is a form of Hydrangea arborescens, also known as Smooth Hydrangea or Hills of Snow, and although native to the southeastern U.S., is cold hardy into zone 4.

Hydrangea arborescens ‘Hayes Starburst’ blooms on new wood, so there is little danger of winter damage to flower buds. We recommend cutting back the woody stems to 12″ in early spring to keep the plants tidy. Hydrangea arborescens prefers to grow in full to half day sun and in a well drained soil that still gets adequate moisture. If there is a common complaint about this species it would be that the flower clusters are so heavy that they weigh down the supporting stems. Some consider this an addition to the plant’s charm, and if it is sited on a slope or above a retaining wall, you could take advantage of its cascading habit. If an upright habit is preferred, situate a large tomato cage over the cut back stalks in spring, which will lend support. The height and spread of this shrub can remain a manageable 3′  x 3′, if pruned annually.
