Throughout early and late fall, the branch tips of Tardiva panicle hydrangea (Hydrangea paniculata 'Tardiva') are graced with masses of small, white, fertile flowers, surrounded by sterile, large, showy white petals that age to pink. One of the larger panicle hydrangeas, this cultivar can grow to 6 to 8 feet tall, and can be trained to a tree form. It requires regular watering in extreme heat.

Hydrangeas are best grown in full sun to partial shade and in moist soil. They bloom on the current season's wood—thus, pruning can be a good way to control growth. They are insect- and disease-resistant, but young plants need protection from rabbits.
