Common names
Hydrangea macrophylla 'Tokyo Delight' (L).
ToxicityTo humans
The common name for Hydrangea macrophylla 'Tokyo Delight' is Hydrangea. Hydrangeas are considered to have low toxicity to humans. However, if ingested, parts of the plant can cause stomach upset, with symptoms including nausea, vomiting, and diarrhea. This is due to the presence of cyanogenic glycosides in the leaves and flower buds, which can release cyanide in the body. Ingesting large quantities could potentially result in more serious symptoms, but such cases are rare.
To pets
The Hydrangea plant can be toxic to pets if ingested. The symptoms of poisoning in pets may include vomiting, diarrhea, depression, and lethargy. In some cases, ingestion can also lead to an increase in heart rate and hyperthermia. Cyanogenic glycosides, which are present in the plant, are the main toxic agents that can release cyanide when metabolized. Pets consuming parts of the Hydrangea plant should receive prompt veterinary attention to manage symptoms and prevent more serious complications.

WaterBigleaf Hydrangeas require consistent moisture and should be watered deeply about three times a week, ensuring the soil is moist but not waterlogged. During periods of high heat or dry spells, increase watering to maintain soil moisture. Each watering session for an established plant should consist of about 1 to 1.5 gallons of water. Monitor the plant's leaves for signs of wilting, which indicate the need for more water, and during the winter, reduce watering frequency since the plant will be dormant.
LightBigleaf Hydrangea thrives in conditions where it receives morning sun and afternoon shade. The ideal spot is one where the plant is protected from the intense midday heat but can soak up gentle morning rays. Avoid placing it in full shade or full sun, as too little light can inhibit blooming, while too much can scorch the leaves.
TemperatureBigleaf Hydrangea prefers a range where daytime temperatures are between 65°F and 75°F, with nighttime temperatures slightly lower but ideally not below 50°F. This plant can generally tolerate temperatures as low as 20°F, but hard freezes may damage the flower buds. The optimal growing conditions for this hydrangea are moderate temperatures with high humidity.
PruningBigleaf Hydrangea should be pruned to remove dead branches and encourage the plant's natural shape, typically immediately after flowering has ceased, as it blooms on old wood. Lightly prune just above the first pair of healthy buds below the spent blooms. Pruning too late in the season may result in cutting off next year's flower buds, so early summer or late spring is ideal.
CleaningAs needed
SoilThe best soil mix for Hydrangea, commonly known as hortensia, should be rich, porous, and well-draining with an even mix of peat, compost, and pine bark. Hortensias prefer a soil pH that affects bloom color, ranging from 5.2 to 5.5 for blue flowers and 6.0 to 6.2 for pink flowers.
RepottingHortensias should be repotted every 2-3 years or when the root system outgrows the container. This will ensure the plant has enough space and fresh soil to continue growing healthily.
Humidity & MistingHortensias thrive in environments with high humidity levels, ideally between 60% to 70%. If indoor air is too dry, consider using a humidifier or placing a water tray nearby to increase humidity.
Suitable locationsIndoor
Place hortensia in bright, indirect light and maintain high humidity.
Outdoor
Ensure partial shade, shelter from winds, mulch well, and keep soil moist.

Life cycleThe 'Tokyo Delight' hydrangea, a cultivar of Hydrangea macrophylla, begins its life cycle when a seed germinates in spring, given appropriate moisture and soil conditions. Emerging as a seedling, the plant then develops a root system and foliage through vegetative growth. Over the next few years, it matures and forms a woody structure, allowing it to withstand colder temperatures and become a perennial presence in the garden. The hydrangea enters a particularly prolific phase of blooming in early to mid-summer, showcasing large mophead flowers that shift color based on soil pH. After the flowering period, which can last through late summer, the plant sets seeds which may drop and germinate nearby, beginning a new cycle. During the winter months, the 'Tokyo Delight' hydrangea becomes dormant, losing its leaves and storing energy in the roots for the next growing season.
PropogationPropogation time
Spring-Early Summer
The most popular method for propagating Hydrangea macrophylla 'Tokyo Delight', commonly known as Bigleaf Hydrangea, is through softwood or semi-hardwood cuttings. This technique is typically performed in late spring to early summer. A healthy, non-flowering shoot is selected and a cutting about 5 to 6 inches long with several leaves is taken. The lower leaves are removed, and the cut end is dipped in rooting hormone powder to encourage root development. This cutting is then inserted into a pot filled with a well-draining potting mix or a 50:50 blend of peat and perlite. The pot is placed in a warm, humid environment but out of direct sunlight to prevent desiccation. Regular misting helps maintain humidity levels, and roots usually form within 4 to 6 weeks.
