Bigleaf Hydrangea is a popular old-fashioned deciduous small to medium size shrub with many sparsely branched stems suckering from ground level. Large showy flower heads of two types, hortensia (florist's type, hemisphere of showy sterile flowers) or lacecap (ring of showy sterile flowers around a center of less showy fertile flowers), in colors ranging from blue to pink are the major asset. Plants are particularly useful along woodland edges or other partly shady sites. Some of the small size cultivars with very large flower clusters are used as potted house plants or for table arrangements.
Plant Habit or Use:
Groundcover, shrub, small shrub, medium shrub, interiorscape
Pink to blue, spent flowers on hortensia types can be mildly showy.
Capsules, mostly on the lacecap types, not particularly showy.

Flower color is affected by the soil pH of the site via the aluminum concentration; acid tends to have blue flowers, while pink is often on higher pH sites, but this is not always tree.
