Answer: If you're going to grow hydrangea in Utah, choose the hardy oak leaf hydrangea rather than the more tender hydrangea macrophylla. The Oakleaf Hydrangea, Hydrangea quercifolia, is an upright, deciduous shrub with a broad, rounded habit that typically grows 4-6' tall. It features elongated white flowers which slowly turn pinkish purple with age. It also may be used for backgrounds, accents or specimens, foundation plantings or hedges. Best grown in fertile, medium wet, well-drained soil in full sun to part shade. Mulch root zone in summer and provide somewhat constant moisture. Little pruning is needed, but should be done any time after flowering.
