Hydrangeas are popular flowering plants known for their large, beautiful blooms and vibrant colors. They are native to Asia and North America, especially in countries like Japan, China, and Korea. This article will explore the origins, history, characteristics, types, and uses of the Hydrangea in simple terms.
Introduction of Hydrangea
The Hydrangea is a genus of about 70 to 75 species of flowering plants. These plants can be shrubs, small trees, or even climbing vines. Most Hydrangeas grow to be between 1 to 3 meters tall. They can be either deciduous, which means they lose their leaves in winter, or evergreen, meaning they keep their leaves all year round. The flowers usually bloom from early spring to late autumn, providing months of colorful display.
Origins of Hydrangea
Hydrangeas are believed to have been first discovered in Japan because they are frequently mentioned in Japanese poetry and historical writings. However, since they are native to many regions, including parts of North America, it's hard to say exactly where they were first found. Fossil records show that Hydrangeas have been growing in North America for millions of years.
History of Hydrangea
Hydrangeas were introduced to Europe in the 1700s. In 1736, a colonist brought a North American Hydrangea variety to England. Around the same time, two Japanese types, Hydrangea macrophylla and Hydrangea serrata, were brought to Europe by doctors and botanists Engelbert Kaempfer and Carl Peter Thunberg. Thunberg is credited with naming these plants. Throughout the 1800s, European plant collectors continued to bring back different Hydrangea specimens from Asia. Some of these, like the Hydrangea macrophylla 'Mariessii', are still sold in flower shops today.
Characteristics of Hydrangea
Hydrangeas are known for their large flower heads, which can be round like a ball or shaped like a cone. The flowers come in many colors, including blue, purple, pink, red, white, and green. One interesting feature of some Hydrangeas, especially Hydrangea macrophylla and Hydrangea serrata, is that their flower color can change depending on the acidity of the soil they are planted in.
Types of Hydrangea
Also known as French Hydrangea, this is one of the most common types. It originates from Japan and is known for its large leaves and impressive flowers. Bigleaf Hydrangeas can change color based on soil acidity and are easy to care for, requiring little pruning.
This type can grow up walls, fences, or arbors, making it great for adding height to gardens. It produces fragrant white flowers in the summer. Climbing Hydrangeas are hardy and can grow in various sun conditions, from full sun to partial shade.
Native to North America, Smooth Hydrangeas are known for their large, round white flower clusters. A popular variety is 'Annabelle', which has huge blooms that can reach up to 12 inches across. They are hardy plants that can tolerate colder climates and bloom reliably each year.
These Hydrangeas have cone-shaped flower clusters and can handle full sun and cold winters. They often start white and may turn pink as they age. Varieties like 'Limelight' are popular in gardens.
