Hydrangea macrophylla aka Hydrangea

Taxonomy

Hydrangea macrophylla, also known as bigleaf hydrangea, French hydrangea, or lacecap hydrangea, is a deciduous shrub native to Japan. This compact and rounded plant grows up to 2 meters tall and 2.5 meters broad, featuring large heads of pink or blue flowers during the summer and autumn seasons. Its dark green, toothed leaves add to its overall beauty. Widely cultivated in various climates worldwide, this exciting rebloomer offers stunning color combinations throughout the year. The vibrant blooms initially open as chartreuse green with hints of pink, gradually deepening to a violet red while still retaining highlights of chartreuse-green. Adding to its charm, each flower showcases a small blue eye at its center. This Hydrangea species should not be mistaken for H. aspera 'Macrophylla'.

How to care for Hydrangea

Difficulty

With a bit of knowledge and dedication, you can successfully care for Hydrangea, making it a rewarding choice for those seeking a moderate challenge.

Water

Hydrangea should be watered regularly, allowing the soil to dry out between waterings.

Soil

Hydrangea loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Hydrangea requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Hydrangea will be sure to bring you many years of beauty and enjoyment.

Dormancy

During the wintertime, it is common for Hydrangea plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.

Toxicity

Hydrangea is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Humidity

The Hydrangea does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.

Fertilizer

The growth of Hydrangea is gradual and it doesn't necessitate any additional fertilizers. Replacing the soil in its pot once a year should suffice to provide the plant with sufficient nutrition. It's important to keep in mind that plants derive their energy from the sun's rays, not fertilizers.

Region of origin

Hydrangea’s native range is Asia and the Americas.

Flower

If you provide your Hydrangea with adequate amounts of sunlight and water, it will bloom.
