Hyacinth and hydrangea are two different species of flowering plants, each possessing their own unique characteristics and beauty. While hydrangea is a shrub from the Saxifragaceae family, typically growing 1-4 meters high in clusters, hyacinth is a perennial herb belonging to the hyacinth family with a shorter stature and bulb-like structure below the surface (The Plant Aide).

These popular plants can serve as delightful additions to home gardens, offering an attractive appearance and elevating the overall decor (Homifine). This article aims to delve into the key differences and similarities between hyacinth and hydrangea, providing valuable insight into their unique traits and care requirements for successful cultivation.

Hyacinth Overview

Origin and Habitat

Hyacinth flowers trace their roots back to the Eastern Mediterranean and were introduced to Europe in the 18th century. They are a part of the asparagus family and are closely associated with Greek mythologysource.

Botanical Description

Each hyacinth bulb produces a single flower stalk that grows 8 to 12 inches tall, accompanied by 4 to 6 strappy leaves. The blossoms open in mid-spring, alongside daffodils and early tulipssource. The flowers come in rich, saturated colors including deep indigo, bright magenta, light pink, purple, and white. Popular cultivars of hyacinth include Blue Jacket (royal blue), Delft Blue (cerulean), and Aidasource.

Hyacinths can be grown outdoors in the ground or in pots, and even indoors in a bulb vase filled with water. They have a moderate growth rate, and while they come back every year, the vigor of their flowers diminishes after a few seasonssource.

Hydrangea Overview

Origin and Habitat

Hydrangeas are versatile flowering plants that come in various types, each with its unique origin and habitat. One such type, the smooth hydrangea, is native to the United States and typically grows as a large shrub up to six feet tall, often utilized as a hedge plant (FTD.com).

Botanical Description

Hydrangeas belong to the shrub category, growing in clusters, and exhibit paper or nearly leathery leaves that are typically round shaped(The Plant Aide). The flowers come in various colors depending on the type and soil conditions, and the plant’s growth is relatively rapid, averaging two feet or more per year(The Spruce).

Size and Growth Habit

Hyacinths and hydrangeas differ in their growth habits and size. Hydrangeas are known for their shrub-like growth, forming large clusters, while hyacinths are herbaceous plants with relatively short stature (The Plant Aide). The smallest hydrangea bushes can reach up to 2 feet tall, whereas the largest ones, like panicle hydrangeas, can grow up to 15 feet tall (Better Homes & Gardens). In contrast, hyacinths have a more compact growth, typically staying much shorter than hydrangeas.

Flower Characteristics

Both hydrangeas and hyacinths have unique flower characteristics. Hydrangea flowers come in a variety of colors and shapes, often arranged in large, showy clusters. Hyacinth flowers, on the other hand, feature a more uniform shape and tend to be smaller in size with densely packed, fragrant blooms on a single stem (Home Stratosphere).

Bloom Times

The bloom times for hydrangeas and hyacinths also vary. Hydrangeas generally bloom in the summer months, with some varieties flowering into the autumn. Bigleaf hydrangeas prefer more shade, while panicle hydrangeas thrive in full sun (FTD). Hyacinths, on the other hand, are known for their spring blooms, adding vibrant color to gardens early in the season.

Choosing Between Hyacinth and Hydrangea

Garden Design Purposes

Hyacinths, being herbaceous plants, are relatively short with fleshy leaves and are perfect for adding a pop of color to flower beds, borders, and containers (The Plant Aide). In contrast, hydrangeas are shrubs, ranging from 2 to 15 feet tall and wide, and are ideal for creating focal points, privacy screens, or hedges in your garden (BHG).

Climate Considerations

Hyacinth bulbs prefer slightly acidic to neutral soil and do best in loose, well-drained soil (The Spruce). Hydrangeas, on the other hand, can thrive in a variety of soil conditions and are suitable for full sun to part shade exposure (Proven Winners). It is crucial to consider your local climate and garden conditions while selecting a plant that will flourish in your yard.

Maintenance Requirements

Maintenance for hyacinths requires proper soil preparation, planting, and watering, while hydrangeas may require pruning, protection from harsh weather, and monitoring soil pH for optimal bloom color. Carefully assess the maintenance and care requirements for each plant and select the one that aligns with your gardening abilities and preferences.


In summary, hydrangeas and hyacinths are both beautiful flowering plants, but they differ in their growth patterns, family classification, and care requirements. Hydrangeas are tall shrubs that belong to the Saxifragaceae family and change color based on soil pH, while hyacinths are shorter perennial herbs from the hyacinth family with various shades of vibrant colors. Understanding these distinctions will assist gardeners in choosing the perfect plant for their landscape and cultivating them successfully.
