Hydrangeas

Hydrangea Plants

Brightly studded with large, globular, mushroom-headed, or broadly conical flowers, hydrangeas richly color borders from July to September. Blooms come in white and shades of pink, blue, or red. Long-lived, deciduous Hydrangea shrubs grow 20 inches to 8 feet high and across. 

Most widely grown are aptly named mophead and lacecap varieties of Hydrangea macrophylla. Yielding pink, mauve, or red blooms on alkaline soils and blue heads in acid conditions, they thrive in fertile ground. Characteristically, lacecaps have an outer ring of large, sterile flowers enclosing tiny, fertile ones that are pink or blue.

Care and Planting

They like dappled sunlight or morning sun and afternoon shade, which suits hydrangeas well. Ensure they are sheltered from frosty winds, as they can damage embryo blossoms

H. macrophylla varieties are reliable seaside plants for relatively frost-free areas. Hydrangea trees and shrubs need damp soil high in organic matter. You can improve poor areas by digging in plenty of well-decayed manure or compost a few months ahead of planting. Also, mulch plants with well-rotted organic matter. You can plant these from March to November.

The Beauty and Versatility of Hydrangea Shrubs

Hydrangeas are a splendid addition to any garden, offering a riot of colors, sizes, and shapes that can breathe life into your outdoor space. These lush, flowering shrubs add a touch of elegance and charm that’s hard to match.

Visual appeal: Hydrangea shrubs are renowned for their large, vibrant blooms that can transform any garden space. The Endless Summer variety offers a continuous display of flowers from early summer to fall, ranging in color from deep blue to pink blooms. The Annabelle hydrangea is famed for its enormous white flower heads, providing a stunning visual impact.

Versatility: Hydrangeas are incredibly versatile, available in a range of sizes and forms to suit various landscaping needs. Dwarf varieties like the Little Lime can fit into smaller gardens or container plantings. Larger cultivars, such as the Limelight, can grow up to eight feet tall and wide, making a dramatic statement as a hedge or standalone specimen.

Water needs: While most hydrangeas require consistent moisture, many varieties have adapted to tolerate brief periods of drought once established. Mulching and proper soil preparation can enhance their water retention, making them more resilient and reducing the need for frequent watering.

Attracts pollinators: With their large flower heads, hydrangeas are excellent at attracting pollinators such as bees and butterflies to your garden. This not only aids in the health of your garden's ecosystem but also ensures the pollination of surrounding plants.

Low maintenance: Hydrangea shrubs thrive in a variety of soil types as long as the soil is well-drained and rich in organic matter. Annual mulching and moderate fertilization can help ensure vibrant blooms without the need for constant care.

Pruning flexibility: Some varieties, such as the Panicle hydrangeas (Hydrangea paniculata), benefit from annual pruning to enhance blooming and maintain shape. Others, like the oakleaf hydrangea bushes (Hydrangea quercifolia), require minimal pruning and can be left to grow naturally beautiful.

Frequently Asked Questions

Hydrangeas are a gardener's delight, offering a spectacular display of blooms that can enhance any outdoor space. To assist you in selecting and caring for these beautiful plants, here are some key questions and answers.

What types of hydrangea shrubs are best for my garden?

It depends on your climate, soil, and desired aesthetic. Endless Summer varieties bloom throughout the season and adapt well to various climates. For large, dramatic blooms, consider the Annabelle or Limelight hydrangeas. Dwarf varieties like Little Lime are perfect for smaller spaces.

How often should I water my hydrangea plants?

Water them deeply 1-3 times a week, depending on your climate and soil drainage. Mulching can help retain soil moisture and reduce the frequency of watering.

Can I change the color of my hydrangea flowers?

Yes, for certain types like the Hydrangea macrophylla, you can influence the color by adjusting the soil pH. For blue flowers, the soil needs to be more acidic (pH below 6), and for pink flowers, it should be more alkaline (pH above 7). Adding garden sulfur for blue flowers or ground limestone for pink flowers can help adjust the pH.

When is the best time to plant hydrangeas?

The best time to plant them is in early spring or fall when the weather is cooler. This allows the plants to establish their root system before the extreme temperatures of summer or winter.

How do I prune my hydrangea shrubs, and when is the best time to do it?

For types that bloom on old woody stems (last year's stems), prune right after flowering. For varieties that bloom on new wood (current year's growth), prune in late winter or early spring before new growth begins.
