- Toxicity
To humans
The panicle hydrangea, specifically the Hydrangea paniculata 'Bombshell' (PBR), is considered mildly toxic to humans if ingested. The plant contains compounds called cyanogenic glycosides, which can release cyanide in the body. Symptoms of poisoning may include nausea, vomiting, and diarrhea. In severe cases, ingestion could lead to more serious symptoms such as dizziness, rapid pulse, or increased body temperature due to cyanide’s potential to interfere with oxygen transport in the blood. However, serious cases of poisoning in humans are rare, as considerable amounts of plant material must be consumed to cause these effects.
To pets
The panicle hydrangea, specifically the Hydrangea paniculata 'Bombshell' (PBR), is toxic to pets if ingested. Like in humans, the plant contains cyanogenic glycosides which can lead to cyanide poisoning when the plant parts are chewed and digested. Symptoms of poisoning in pets can include gastrointestinal upset, such as vomiting and diarrhea, depression, and lethargy. In more severe cases, cyanide poisoning may result in difficulty breathing, increased heart rate, and seizures. It is important to prevent pets from ingesting parts of this plant and to seek veterinary care if a pet is suspected to have eaten any quantity.

- Water
Panicled hydrangeas like 'Bombshell' should be watered deeply and thoroughly, aiming to keep the soil consistently moist but not waterlogged. It's generally best to water these plants once a week with about one to two gallons of water, but this may need to increase to twice a week during hot, dry spells. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. Use a slow trickle or soaker hose to allow water to penetrate deeply into the soil, promoting healthy root growth. Adjust watering based on rainfall, more during dry periods and less when natural precipitation is sufficient.
- Light
Panicled hydrangeas like 'Bombshell' thrive best in full sun to partial shade. An ideal location would offer morning sunlight and afternoon shade, especially in hotter climates, to protect the plant from intense midday heat. Too much shade can result in fewer blooms, so aim for a spot that receives at least 4 hours of direct sunlight each day.
- Temperature
Panicled hydrangeas like 'Bombshell' can tolerate a range of temperatures, but they perform best when daytime temperatures are between 65°F and 75°F. They can survive winter cold down to about -30°F but might need protection in these extreme conditions. Ideal growing conditions include warm summers and cool winters, and they can handle temperatures up to around 95°F without stress.
- Pruning
Panicled hydrangeas like 'Bombshell' should be pruned to maintain shape and to remove any dead or weakened stems, which promotes healthy growth and better blooms. The best time to prune is late winter or early spring before new growth begins. They should be pruned annually since they bloom on new wood; cutting back about one-third of the older stems each year can help maintain vigor.
- Cleaning
As needed
- Soil
Panicled Hydrangea 'Bombshell' thrives in well-drained, moist soil rich in organic matter with a pH that is slightly acidic to neutral, around 5.5 to 7.0. An ideal soil mix can be made of equal parts garden soil, compost, and peat moss to ensure good drainage and fertility.
- Repotting
Panicled Hydrangea 'Bombshell' typically requires repotting every 2-3 years to replenish the soil and provide room for root growth. Repot in spring before active growth begins.
- Humidity & Misting
Panicled Hydrangea 'Bombshell' prefers average to high humidity levels, ideally ranging between 40% and 70%. Ensure good air circulation to prevent moisture-related diseases.
- Suitable locations
Indoor
Ensure bright indirect light, moist soil, and adequate humidity for Panicled Hydrangea.
Outdoor
Plant in morning sun, afternoon shade, and well-draining, moist soil for Panicled Hydrangea.
Hardiness zone
3-8 USDA
- Life cycle
The life of Hydrangea paniculata 'Bombshell' begins with seed germination, which occurs when the temperature and moisture conditions are ideal, typically in the spring. Following germination, the seedling stage involves root and shoot growth until it becomes a young plant. As the plant enters the vegetative stage, it develops a robust root system and lush foliage during the growing season. The hydrangea then enters the flowering stage, generally in early to late summer, where it produces large, showy flower clusters that can range from white to pink. After pollination and fertilization, it reaches the fruiting stage where seeds develop for the next generation. Finally, in the dormant stage during fall and winter, the hydrangea's growth slows and it may lose leaves, conserving energy until the next growing season.
- Propogation
Propogation time
Spring-Early Summer
The most favored method for propagating Hydrangea paniculata 'Bombshell' is through softwood cuttings. This technique is commonly carried out in late spring or early summer, when new growth is still tender and flexible. Softwood cuttings should be about 4 to 6 inches (10 to 15 cm) long and include several pairs of leaves. The lowest set of leaves is removed, and the cut end of the stem is dipped in rooting hormone to encourage root development. The prepared cutting is then inserted into a well-draining growing medium like a mix of peat and perlite or vermiculite. The cuttings must be kept moist and in a warm environment with indirect light until roots develop, which generally takes 4 to 8 weeks. Once rooted, the young plants can be gradually acclimated to outdoor conditions and eventually transplanted into the garden.
