The Grandiflora Hydrangea, Hydrangea paniculata, is a common American garden plant and highly valued for its vigor and bloom dependability. Sterile flowers appear in August and remain on the plant until the first hard frost.
The large conical shaped white flower heads turn to pink in the fall with gray-green leaves. Sent to America from Japan in 1861, this continues to be one of the best loved varieties. The blooms can easily be used for drying. 6+ foot height at maturity.
