Smooth (H. arborescens): ‘Annabelle’ is the most popular variety. Smooth hydrangeas flower best in full sun, but southern gardeners should site the plants in part shade. Bigleaf (H. macrophylla): Bigleaf hydrangeas are the classic florist types of hydrangea that everyone loves, but not everyone can grow. Bigleafs grow best with partial shade in moist, well-drained soils. Most are hardy to Zone 5 or to Zone 4 with winter protection. Panicle (H. paniculata): Tough and easy to grow, panicle hydrangeas produce cone-shaped flowers. They prefer full sun and survive in all but the coldest climates (Zone 3). Panicles bloom later than other varieties, usually midsummer. Heights can range from three to 10 feet, depending on the variety. Oakleaf (H. quercifolia): These plants have oak-shaped leaves, which turn eye-catching shades of burgundy, rust, or orange in the fall. The white flower heads usually transform to pink or tan as the weather cools. Cultivars of this native species, generally hardy to Zone 5, do well in dry soils and in sun to partial shade.
