ToxicityTo humans
The plant commonly known as panicle hydrangea is not considered highly toxic to humans; however, all parts of the plant contain cyanogenic glycosides, which can release cyanide when damaged or chewed. Ingesting large quantities could lead to poisoning. Symptoms of poisoning might include stomach upset, nausea, vomiting, and diarrhea. In rare cases and after consuming significant amounts of plant material, more severe symptoms could occur due to the release of cyanide, potentially leading to breathing difficulties, dizziness, fainting, and potentially more serious effects that could require medical attention.
To pets
Panicle hydrangea is similarly toxic to pets, particularly cats and dogs, as it is to humans. As with human toxicity, the plant contains cyanogenic glycosides, which can produce cyanide when plant parts are chewed or ingested. Symptoms of poisoning in pets may include vomiting, diarrhea, and depression. In severe cases, where larger quantities are consumed, it might lead to an increased heart rate, hyperventilation, lethargy, seizure, and collapse. The toxicity may vary depending on the size of the pet and the amount ingested, and it is advised to consult a veterinarian if a pet has eaten any part of the panicle hydrangea.

WaterThe Peegee Hydrangea should be watered deeply once a week, providing about 1 inch of water each time to sustain its large blooms and green foliage. During hot and dry periods, this may need to be increased to twice a week. The soil should be kept moist, but not waterlogged. It’s best to water the plant at its base to avoid wetting the foliage, which can lead to fungal diseases. Measure the amount of water with a rain gauge to ensure the plant receives a consistent amount, which is particularly crucial during the plant's first few years to establish a strong root system.
LightThe Peegee Hydrangea thrives in full sun to partial shade. It prefers morning sun with afternoon shade or dappled light throughout the day. The ideal spot would be one where it's protected from the harsh afternoon sun, especially in the southern parts of its range, to prevent leaf scorch.
TemperaturePeegee Hydrangeas are hardy and can tolerate a range of temperatures but perform best when the temperature is between 65 to 75 degrees Fahrenheit. They can withstand winter cold down to about -30 degrees Fahrenheit, and summer temperatures as high as 95 degrees Fahrenheit. Sudden frosts or prolonged exposure to temperatures below the hardiness threshold can damage the plant.
PruningThe Peegee Hydrangea should be pruned in late winter or early spring before new growth begins. Pruning encourages healthy growth, removes dead or crossing branches, and can control the size of the plant. It's recommended to remove about one-third of the oldest stems annually to rejuvenate the plant. The best time for major pruning is every few years to achieve a more manageable size and shape.

Life cycleHydrangea paniculata 'Big Ben', commonly known as the panicle hydrangea, begins its life cycle when the dormant buds break in spring, initiating new growth. Leaves emerge, followed by rapid stem elongation, leading to the development of large, conical flower panicles by mid to late summer. The white flowers bloom and gradually transition to pink and then to a beige color as they age and set seed through late summer into fall. In autumn, the plant's leaves turn yellow and eventually drop off as it enters dormancy for the winter period. The plant remains in this dormant state, enduring frosts and snow, until the warmth of spring reactivates its growth cycle for the following year. With proper care, the hydrangea can continue this life cycle for many years, growing larger and producing more abundant blooms as it matures.
PropogationPropogation time
Late Winter-Early Spring
The most popular method to propagate Hydrangea paniculata 'Big Ben', commonly known as Panicle Hydrangea, is through softwood cuttings. This is best done in late spring to early summer when the plant’s new growth is still tender and flexible. Cut a 4 to 6-inch long portion of the stem just below a leaf node using a clean, sharp pair of shears. Remove the lower leaves and dip the cut end into a rooting hormone powder to encourage root development. Plant the cutting in a pot filled with a moist potting mix and cover it with a plastic bag or place it in a propagator to maintain humidity. Keep the pot in indirect sunlight and ensure the soil remains slightly moist but not soggy. Roots typically develop within 4 to 6 weeks (approximately 28 to 42 days).
