Hydrangea All Summer Beauty
Since the deciduous Bigleaf Hydrangea blooms on large buds formed on previous season's growth, any pruning should be done immediately after flowering. Long popular as a florist's plant, Bigleaf Hydrangea performs well in moist, rich garden soil in partial sun to fairly deep shade, where it can grow 4 to 8 feet tall. Be sure that tree roots are not competing with the roots, since this will slow growth dramatically. Flowers are bluish in acid soil, pink in neutral. This plant is considered mostly allergy free and causes little or no allergy problems in most people.
