Hydrangea, a shade-loving beauty, offers huge bouquets of clustered flowers, in various arrangements from mophead to lacecap, from summer through fall. Varieties of hydrangea differ in size of plant and flower panicle, flower color, and blooming time.
PeeGee hydrangeas grow into small trees; the flowers turn russet and cling into winter. Oakleaf hydrangeas have the most handsome foliage, which reddens dramatically in fall. Some of the newer hydrangeas feature huge flowers on compact plants, ideal for containers and small gardens.
Hydrangeas thrive in a moist, fertile, well-drained soil in partial to full shade. If you're seeking blue hydrangea flowers, check your soil's pH level and apply aluminum sulfate in spring to lower pH to the 5.2-5.5 range. The change in hydrangea flower color results from lower pH and higher aluminum content in the soil.
