Whether planted in containers or in a garden bed, few plants provide a bigger impact than a hydrangea. Lacecap, oakleaf, panicle, climbing, smooth, and large-leafed hydrangeas bring diverse texture, color, and form to the summer landscape. Gardeners who crave colors from the cool side of the color wheel, such as pink, purple, white, and blue, will delight in the mix of color hues that are available, sometimes multiple colors on a single shrub. Hydrangeas are best planted in moist, rich soil. This is the rare flowering shrub that does fairly well in shady conditions, but for best performance, most hydrangeas do like to experience some sun in the morning.
Most commercially-available hydrangea cultivars are derived from a relatively few species of the hydrangea genus: H. arborescens (smooth hydrangea), H. macrophylla (bigleaf hydrangea), H. paniculata (panicle hydrangea), H. anomala (climbing hydrangea), H. quercifolia (oakleaf hydrangea), and H. serrata (mountain hydrangea).
Warning
Hydrangeas are toxic to people, The buds, flowers, and leaves of hydrangea plants contain glycoside amygdalin, which can break down to produce cyanide.
These 14 hydrangeas can be a perfect fit for your landscape.

Incrediball® Hydrangea (Hydrangea arborescens 'Abetwo')

If plant breeders are sometimes guilty of hyperbole in their plant name selections, this is not the case with Incrediball—the commercial name for the 'Abetwo' cultivar of H. arborescens. In spite of the huge, densely packed 12-inch flowers the shrub produces in abundance, the sturdy stems on this plant will not allow the flowers on this white hydrangea to flop into the mud. One potted plant will make a gorgeous anchor in your summer border, or you can plant several for a showy hedge.
- Native Area: H. arborescens is native to the eastern United States
- USDA Hardiness Zones: 3 to 9
- Height: 4 to 5 feet
- Sun Exposure: Full sun to part shade

Keep your soil on the acidic side if you want to achieve the most intense blue blooms possible from your 'Nikko Blue' hydrangea bush. This mophead variety blooms earlier than most, usually beginning in June and endures for two months. Provide winter protection in USDA hardiness zone 5 because as flowers are produced from the buds that formed on last year's stems. This is a cultivar of H. macrophylla, which is also known as bigleaf hydrangea.
- Native Area: H. macrophylla is native to Japan
- USDA Hardiness Zones: 6 to 11

Limelight Hydrangea (Hydrangea paniculata 'Limelight')
Green flowers are the little black dresses of the gardening world: they flatter all situations. The chartreuse flowers of 'Limelight' hydrangeas age to a mellow pink as the season progresses. Plants bloom on new wood, making this a very hardy selection in cold areas. Although 'Limelight' is a slightly more compact cultivar of H. paniculata, it is still a fast grower that has been known to reach a height of ten feet; in smaller spaces, look for its smaller cousin 'Little Lime.'
- Native Area: H. paniculata is native to China and Japan
- USDA Hardiness Zones: 3 to 9
- Height: 6 to 10 feet
- Sun Exposure: Full sun to part shade

Cityline® 'Mars' Hydrangea (Hydrangea macrophylla Cityline 'Mars')

A picotee petal adds a little bling to your hydrangea collection. This compact shrub is the perfect addition to your patio garden. Like other Hydrangea macrophylla varieties, soil pH affects bloom color. Cityline 'Mars' shrubs might have multiple colors on the same bush the season following installation as the plants adjust to your unique soil chemistry. The specimen shown here is situated in a garden with a neutral pH, which results in a purple shade hovering just between blue and pink. Maintaining such a narrow pH range is easier to do with container culture than in the ground.
- Native Area: H. macrophylla is native to Japan
- USDA Hardiness Zones: 5 to 9
- Height: 1 to 3 feet
- Sun Exposure: Full sun to part shade

Anyone who inherits a climbing hydrangea specimen is lucky. Hydrangea anomala subsp. petiolaris is notoriously slow to get growing. However, once this self-clinging vine becomes established, it can climb and sprawl 40 feet or more onto fences, structures, and trees. For added interest, look for the variegated climbing hydrangea 'Miranda' (H. petiolaris subsp. petiolaris 'Miranda'), which features creamy yellow leaf margins in addition to ten-inch flower heads.
- Native Area: Himalayas and China
- USDA Hardiness Zone: 4 to 8
- Height: 30 to 50 feet

'Gatsby Pink' Hydrangea (Hydrangea quercifolia 'Gatsby Pink')
Gardeners who cherish North American native plants should not miss the showy oakleaf hydrangea cultivar 'Gatsby Pink.' A season-long spectacle of color, flowers start white and gradually change to pink, then the foliage joins the display in autumn with a brilliant red showing. Because the plants bloom on old wood, oakleaf hydrangeas like 'Gatsby Pink' require a garden in USDA hardiness zone 5 or warmer to prevent winter damage that affects future growth.

Hydrangeas are generally a very easy and trouble-free flowering shrub. However, a variety of fungal leaf spot diseases are possible. You can avoid some of these diseases by watering early in the day and by watering at the base of the plant rather than overhead. If bacterial or viral diseases strike, the affected plant parts should be removed and destroyed. If the plant has been infected by a virus, you might need to remove and destroy the entire plant.
