ToxicityTo humans
Hydrangeas, including the Hydrangea macrophylla variety, are known to be toxic to humans if ingested. The plant contains compounds such as hydrangenol, which can cause gastrointestinal upset, with symptoms including nausea, vomiting, and diarrhea. In some rare cases, more severe symptoms can occur, such as dizziness, rapid pulse, or even respiratory issues. It is advisable to avoid consuming any part of the hydrangea plant to prevent these potential consequences.
To pets
Hydrangeas, including Hydrangea macrophylla, are also toxic to pets, such as dogs and cats. The toxicity is due to the presence of cyanogenic glycoside in the plant.

In more severe cases, ingestion can lead to increased heart rate, heavy breathing, and even seizures. If you suspect your pet has eaten any part of a hydrangea plant, it's important to seek veterinary care immediately.

WaterThe Bigleaf Hydrangea should be watered deeply, ensuring the water reaches the roots, about one to two times per week depending on the climate and soil drainage. These plants prefer consistently moist soil, so during dry spells or hot weather, more frequent watering may be necessary, such as every two to three days. Generally, aim for about 1 gallon of water per watering session for each plant, adjusting for weather conditions. During winter, water less frequently, allowing the soil to dry out slightly between watering to prevent root rot.
LightBigleaf Hydrangeas thrive in a spot with morning sun and afternoon shade, as too much direct sun can scorch their leaves. They can also grow in full shade, however, the blooms may be less prolific. Protection from hot midday sun is particularly critical in warmer climates to maintain the vibrant colors of the flowers.
TemperatureThe Bigleaf Hydrangea is hardy and can tolerate temperatures down to about 5°F, but it thrives best when daytime temperatures are between 65°F and 80°F. These plants can survive up to 95°F, but the foliage may suffer in prolonged heat, especially if not adequately watered. Ideal growing conditions include a location where the plant is shielded from harsh winter winds.
PruningPrune the Bigleaf Hydrangea after it flowers in the late summer to remove spent blooms and any weak or dead branches, which encourages healthy growth and improves the plant's shape. Since hydrangeas flower on old wood, do not prune in the spring as you may cut off the current year's blooms. Pruning every year is not necessary; do so every other year or only when the plant becomes too large or unkempt.
CleaningAs needed
SoilBigleaf Hydrangeas thrive in a soil mix that is rich in organic matter, well-draining yet moist, with an ideal pH range of 5.5 to 6.5. A blend of garden soil, peat moss, and perlite can create an optimal environment for Hydrangea macrophylla 'Shining Angel'.
RepottingBigleaf Hydrangeas should be repotted every 2-3 years or when they outgrow their current pot. The best time to repot is in late winter or early spring, before new growth commences.
Humidity & MistingBigleaf Hydrangeas prefer moderate to high humidity levels, around 50-60%. They benefit from a humid environment, which can be maintained with regular misting or using a humidifier.
Suitable locationsIndoor
Ensure bright, indirect light and maintain soil moisture.

Life cycleHydrangea 'Shining Angel' begins its life as a dormant bare-root or potted specimen that is planted in early spring or fall. It emerges from dormancy with new growth in the spring, developing lush green foliage and robust stems. During late spring to early summer, it enters its flowering stage, producing large, showy bloom clusters that can range in color from pink to blue depending on soil pH. After blooming, if the flowers are not deadheaded, they may develop into seed heads, though hydrangeas are more commonly propagated through cuttings. As fall approaches, the plant's growth slows, and it begins to prepare for winter dormancy by withdrawing nutrients from the leaves, which change color and eventually drop. Over winter, the hydrangea remains dormant, conserving energy until the next growth cycle begins in spring.

Spring-Early Summer
Hydrangea macrophylla 'Shining Angel' from the Black Diamonds Series can be propagated most effectively through softwood cuttings. This is typically done in late spring or early summer when the plant's new growth is still tender but has begun to mature slightly. One would cut a 4 to 6-inch (approximately 10-15cm) section of stem from a healthy parent plant just below a leaf node, where the concentration of growth hormones is high. The bottom leaves are then removed, and the cut end dipped in rooting hormone to encourage root development. The cutting is then placed in a pot with a mixture of peat and perlite, ensuring the leaf nodes are buried where roots will form. The environment should be kept humid, often by covering the pot with a plastic bag or placing it in a greenhouse, and within a few weeks, roots should establish, at which point the new hydrangea plant can be gradually acclimated to less humid conditions.
