Hydrangeas are one of the most popular houseplants in the world. They have been used for centuries in Chinese medicine. Hydrangeas are native to Europe and Asia but they were introduced into North America during the early 1900’s through New York City botanical gardens. Today, hydrangeas are grown all over the world with many varieties being hybridized to create new hybrids. Hybrids are not always better than their parents.
Some hybrids may even be worse than their wild parent species. Hybridization is a very common way plants get better or worse characteristics. Hydrangeas are often confused with roses because both have petals that turn red when exposed to sunlight. However, hydrangeas do not produce flowers like roses do; instead they grow from underground stems called stolons which produce leaves and flowers only once every two years (or less).
Hydrangeas are also sometimes confused with peonies because they have similar looking flower heads. Both hydrangeas and peonies have long stems that grow straight up from the ground. These stems usually end in a spike at the top of the stem called a trumpet or pistil. When these flowers appear, it is known as a showy bloom. Peony flowers are usually flat while most hydrangea flowers have a 3D appearance.
As mentioned above, hydrangeas do not produce flowers every year.
In fact, some varieties may take up to four years to flower for the first time. They do this because by delaying their first bloom they can produce more flowers all at one time during the first (and in some cases second) bloom.
Why air pockets in the soil might cause a plant to die?
The answer is because plants need oxygen for their roots just like we need oxygen for our lungs. This is why it’s important to make sure there are no air pockets in the soil.
If you are growing your cutting in a planter rather than in the ground, be sure to keep it out of the sun because hydrangea cuttings can get sunburn.
In conclusion, hydrangea flowers have been a popular addition to gardens since they were first discovered by Europeans. They come in a wide variety of colors and add a fun contrast to many different types of gardens. They are fairly easy to grow from cuttings and can be enjoyed by people of all ages.

How To Grow Hydrangeas
Learn about the best soil, sun and shade conditions, watering, pruning, root pruning, feeding, flower feeding, repotting, taking cuttings, and more.
In choosing a site select a partly shaded position preferably on the north side of the house where they are protected from the hot afternoon sun. This is most essential for hydrangea varieties that do not tolerate heat and midday sun will prevent blooming. It is important to note that soil should be kept on the dry side since hydrangeas do not like ‘wet feet.
Hydrangeas can be grown from seed, but it is much easier to propagate by cuttings. A new hydrangea can be started with a single leaf and rooted in a small pot of soil or could even be stuck in a glass of water.
When taking cuttings, harvest only the newest wood which is usually found towards the base of the shoot. Cut about 5 cm below a pair of buds and remove the leaves that will be below the cut. This area will be buried in soil so it does not need leaves.
The leaf sticking up acts as a support to help the cutting upright.
