      The common name for Hydrangea macrophylla Love = 'Youme H1917' (PBR) (H/d) is Hydrangea. Hydrangeas are considered to be mildly toxic if ingested due to the presence of cyanogenic glycosides found in the plant’s leaves and flower buds. If parts of the plant are eaten, symptoms of poisoning can include gastrointestinal upset, such as nausea, vomiting, and diarrhea. In some rare cases, more severe symptoms could occur, such as dizziness, lethargy, or confusion due to cyanide release in the body. However, serious toxicity is uncommon, and ingestion of hydrangea typically results in minimal toxicity.

  • water dropWater

    Bigleaf hydrangeas, including Hydrangea macrophylla Love, require consistent moisture, so water them once or twice a week. The soil should be kept moist, but not soggy, to a depth of about 6 inches. During hot or dry periods, you may need to water more frequently to prevent the leaves from wilting. A general rule is to provide about 1 gallon of water per watering session for each plant, adjusting as needed for rainfall and temperature variations.

  • sunLight

    Bigleaf hydrangeas, such as the Hydrangea macrophylla Love, thrive in dappled shade or morning sun with afternoon shade. Avoid placing them in full afternoon sun, as this can cause stress and wilting. A spot that receives bright, indirect light for most of the day is ideal. East-facing locations where the plant can get gentle morning sunlight and shade from the harsher afternoon rays are typically best for these hydrangeas.

  • thermometerTemperature

    Bigleaf hydrangeas like Hydrangea macrophylla Love prefer temperatures between 65°F and 75°F for optimal growth. They can survive temperatures as low as 5°F for short periods once established and properly mulched, but prolonged exposure can damage the plant. In summer, they should be protected from extreme heat above 95°F, which can cause stress and harm to the plant.

  • scissorsPruning

    Prune Bigleaf hydrangeas like Hydrangea macrophylla Love shortly after they finish blooming in summer, as they bloom on old wood. Remove faded flowers and any dead or damaged branches to encourage healthy growth and improve the plant's shape. Pruning too late in the season can remove developing flower buds for the next year, so timing is crucial.

  • circleLife cycle

    The life of a Hydrangea macrophylla, commonly known as Bigleaf Hydrangea, begins with seed germination, where it requires warm and moist conditions to sprout. Once sprouted, the seedling grows into a juvenile plant with characteristic large, glossy leaves and begins to develop a woody stem structure. As the hydrangea matures, it enters the vegetative stage where it focuses on leaf and stem growth. The flowering phase follows, typically in early to mid-summer, where it produces large, showy flower heads that can be pink, blue, or purple depending on soil pH. After pollination, if it occurs, the flowers give way to seed capsules that mature by autumn, allowing the plant to reproduce sexually, although hydrangeas often propagate through vegetative cuttings. Finally, the plant enters dormancy in the winter, reducing metabolic activities to survive cold conditions until the cycle recommences in spring.

    • Propogation time

      Spring to early summer

    • Propogation: The most popular method of propagating the Hydrangea macrophylla, commonly known as bigleaf hydrangea, is through softwood cuttings. This is typically done in late spring or early summer when the plant's new growth is still tender and green but has not fully hardened. Gardeners cut a 4 to 6 inch (about 10 to 15 centimeters) length of stem that includes several leaves and at least one node, or the point on a stem where leaves are attached. The bottom leaves are removed, and the cut end is dipped in rooting hormone before being planted in a moist potting mix. The cutting is then placed in indirect light and kept consistently moist until roots develop, which generally takes about 2 to 4 weeks. After rooting, the new hydrangea plant can be transferred to a larger pot or planted directly in the garden.
