Freshen Up Your Garden: Growing White Hydrangea Bushes

White hydrangeas are beloved by professional landscapers and ornamental gardeners for good reason. They are easy to grow, reliable, and produce an abundance of vibrant flowers. While purple, blue, and pink hydrangea bushes are more common, there are new varieties available in different colors and shapes. These stunning white hydrangeas look glorious alongside succulents, trees, and other forms of greenery, adding a fresh and elegant touch to any garden.

A Rich History of White Hydrangeas

White hydrangeas have a long and illustrious history. Initially discovered in Japan in the 1700s, the Hydrangea genus quickly gained popularity among Asian gardeners and horticulturists. In the 1800s, hydrangeas were introduced to North America and Europe, where they became highly sought-after plants.

White hydrangeas, in particular, have always been a favorite among gardeners. Natural mutations that occurred in pink or blue hydrangeas resulted in the first white flowers. Over time, breeders selectively cultivated white cultivars for their color and other qualities.

White hydrangea bushes hold cultural significance in Japan, where they are used in burial rites to symbolize purity and humility. These graceful flowers also convey elegance and sincere emotions in the language of flowers. They are often used in bridal bouquets and other ceremonial arrangements.

Today, white hydrangeas are cherished by gardeners worldwide for their stunning blossoms and low maintenance requirements. Whether planted in gardens, borders, or pots, pink and white hydrangea bush varieties are guaranteed to impress and add beauty to any environment.

Discovering White Hydrangea Plant Varieties

White hydrangeas are popular flowering bushes known for their large, showy blooms and ease of cultivation. They come in various varieties, each with its own unique characteristics in terms of flower size, shape, and color. Whether you prefer a classic white hydrangea or a more unique option, there is a white hydrangea bush plant that will suit your garden’s needs. Here are some popular white hydrangea varieties:


The Annabelle variety is admired for its hardiness and ability to thrive in various climates. This deciduous shrub can grow up to 10 feet tall and wide, but it can be kept smaller through pruning. Annabelle hydrangeas prefer partial to full shade and moist, well-drained soil. With their elegant and graceful appearance, these white hydrangea-style flower bushes are a popular choice for landscaping and gardening. They can also be used as cut flowers in bouquets or arrangements due to their long-lasting nature and striking beauty.


Incrediball white hydrangeas are another variety known for their large and impressive blooms. This variety is a cultivar of the Annabelle hydrangea but produces even bigger flowers, reaching up to 12 inches in diameter. Like Annabelle hydrangeas, Incrediball hydrangeas thrive in partial to full shade and well-drained soil. They can grow up to 5 feet tall and wide but can be kept smaller through pruning. Their sturdy and long-lasting blooms make them a popular choice for cut flowers and floral arrangements.


White hydrangeas of the Limelight variety display cone-shaped blooms that start as a soft, lime-green color before turning white in late summer. These hydrangeas are known for their vigorous growth and ability to tolerate more sun than other varieties. They can grow up to 8 feet tall and wide but can be kept smaller. Limelight hydrangeas prefer well-drained, moist soil and can tolerate some drought. They also respond well to pruning and can be shaped into tree forms or hedges.

PeeGee hydrangeas, also known as Hydrangea paniculata ‘Grandiflora,’ produce cone-shaped blooms rather than round ones. These white blooms can reach up to 12 inches in length and often develop pink or green hues as they age. The PeeGee variety is known for its hardiness and ability to tolerate various conditions, including full sun and drought. It can grow up to 20 feet tall and 10 feet wide, but pruning can help maintain a smaller size.

Snow Queen

The Snow Queen variety produces large, rounded blooms that are pure white and can reach up to 6 inches in diameter. Unlike other white hydrangea bush varieties, Snow Queen blooms on new wood, allowing for pruning in late winter or early spring without affecting next year’s flowers. Snow Queen hydrangeas prefer partial shade to full sun and moist soil. They are hardy and resistant, making them an excellent choice for low-maintenance gardening.

Choosing the Perfect White Hydrangea for Your Garden

With numerous white hydrangea varieties available, how do you choose the best one for your garden? Each variety has its own care requirements and ideal growing conditions. Here are four common types of hydrangeas and their characteristics:

  1. Bigleaf (H. macrophylla): This classic white hydrangea variety is a favorite among florists. It thrives in partially shaded locations with well-drained soil. Hardy up to Zone 5 (or Zone 4 with proper winter protection).

  2. Smooth (H. arborescens): Anabelle is the most popular variety of this type. It blooms best under the sun but prefers partial shade in southern regions.

  3. Oakleaf (H. quercifolia): These plants have oak-shaped leaves that turn eye-catching colors in autumn. The white flower heads eventually turn tan or pink as the weather cools. Oakleaf hydrangeas can withstand Zone 5 conditions in dry soils.

  4. Panicle (H. paniculata): Panicle hydrangeas produce cone-shaped flowers and are adaptable and easy to grow. They prefer full sun but can thrive in various climates except the coldest ones. Panicles typically bloom in midsummer.

Consider the growing requirements and aesthetic appeal of each variety before making your choice. By selecting plants with similar needs and complementary colors and textures, you can create a stunning garden display.

Planting White Hydrangeas with Care

To ensure your white hydrangeas thrive, it’s important to plant them correctly and provide them with the optimal conditions. Here are some tips for planting and caring for white hydrangea bushes:

The Best Time to Plant Hydrangeas

Fall and early spring are the best seasons for planting hydrangeas. This timing allows the shrubs to establish a strong root system before producing flowers. Planting in the late afternoon or early morning, when the weather is cooler, helps protect the blooms from heat stress.

The Best Soil for White Hydrangeas

White hydrangeas prefer soil with organic material and good drainage. Moist soil is ideal, but waterlogging should be avoided. If your soil is heavy, adding compost can improve its quality.

The Best Planting Location for Hydrangeas

Choose a sheltered location for your hydrangea bush that receives sunny mornings and shady afternoons. Avoid planting directly under trees, as competition for nutrients and water may occur. Planting beds beside your home is a common choice for many gardeners.

When planting, dig holes that are wider than the root ball and consistent in depth. The plant should sit slightly higher or level with the surrounding soil. Adding a slight mound helps with water drainage away from the plant’s base.

Propagating white hydrangeas is a simple process. Bend a branch to touch the soil, scratch the bark where it makes contact, and then fill the trench and place a stone or paver on top. Once the branch develops its root system, it can be planted in another location.

Companion Plants for White Hydrangeas

Pairing white hydrangeas with the right companion plants can create a stunning garden display. Here are some ideas for plants that complement white hydrangeas:

  • Hostas: Shade-loving plants with various leaf colors and textures that create an elegant garden look.
  • Ferns: Shade-loving plants with delicate fronds that provide a beautiful contrast against white hydrangea blooms.
  • Coral Bells: Perennial plants with colorful foliage that add vibrancy to a white hydrangea garden.
  • Bleeding Hearts: Shade-loving plants with delicate, heart-shaped flowers that create a romantic and whimsical look.
  • Astilbe: Perennials with feathery plumes of flowers that add a soft, delicate texture to a garden with white hydrangeas.
  • Cornflowers: Blue or pink blooms that complement the white hydrangeas, creating a beautiful contrast in color.

When selecting companion plants, consider their soil conditions, light requirements, and overall aesthetic appeal. By choosing plants with similar growing requirements and complementary colors and textures, you can create a harmonious garden display.

Caring for Your White Hydrangea Plants

While white hydrangeas may seem delicate, they don’t require tedious care. Here are some basic tips for caring for your white hydrangeas:

  1. Mulching: Add mulch around the base of the plants to keep the soil cool and moist. Organic mulch improves soil texture and provides nutrients over time.

  2. Watering: Regularly water your plants to ensure they receive about an inch of water per week. Deep watering encourages root growth. While hydrangeas in general need consistent watering, smooth and bigleaf hydrangeas have a higher water requirement.

  3. Pest Protection: Choose cultivars with resistant traits to protect your flowers from pests. However, pests are usually uncommon, and proper care for your hydrangeas will keep them healthy.

Maintaining the Color of Your White Hydrangeas

White hydrangeas naturally undergo color changes as they age and grow. If your blooms are changing shades, it is part of their normal process. To maintain the white color for as long as possible, keep your hydrangeas healthy. Sunlight exposure affects the color of the blooms, so ensure they receive the right amount of shade. Proper watering and fertilization also contribute to the longevity of white blooms.

Storing and Preserving White Hydrangea Flowers

If you want to store or preserve white hydrangeas, follow these steps:

  1. Cut the stems at an angle and place them in a bucket of water.
  2. Remove any leaves that will be submerged to prevent bacterial growth.
  3. Mist the blooms with water and wrap the stems with damp paper towels before covering them with a plastic bag.
  4. Store the bouquet away from direct sunlight and heat sources.
  5. Change the water every few days, trim the stems, and mist the flowers to prolong their vase life.

To dry the flowers, hang them upside down in a place away from direct sunlight. The dried blooms can be used in arrangements. Another preservation method involves dipping the stems in alum powder, which helps preserve their color and shape.

Tips and Precautions for Growing White Hydrangeas Outdoors

Growing white hydrangeas in your outdoor garden requires proper care and attention. Here are ten tips and precautions to keep in mind:

  1. Choose the right location: White hydrangeas prefer partially shaded areas with moist, well-drained soil. Avoid planting them in full sun to prevent them from drying out.

  2. Plant at the right time: Early spring or fall is the best time to plant white hydrangeas when temperatures are cooler and moisture levels are higher.

  3. Mulch around the base: Apply organic mulch to retain moisture around the roots and keep the soil cool.

  4. Water regularly: Provide regular watering, especially during warm summers. Hydrangeas need deep watering once or twice a week, depending on the weather conditions.

  5. Fertilize sparingly: Avoid over-fertilization, as it can reduce bloom production. Use a well-balanced fertilizer in spring and fall, refraining from fertilizing in summer.

  6. Prune at the right time: Prune in early spring or late winter, removing any damaged branches to improve air circulation.

  7. Protect from frost: Cover or move your white hydrangeas indoors if frost is expected, as they are sensitive to cold temperatures.

  8. Watch for pests: Regularly check your plants for signs of pests or infestations, and take appropriate measures to protect them.

  9. Provide support: Some varieties, such as Annabelle and Incrediball, may require support to prevent branches from bending or breaking. Use stakes as the plant grows.

  10. Be patient: White hydrangeas may take a few years to establish and produce abundant blooms. With proper care and patience, you will be rewarded with a beautiful display of white flowers.
