hydrangea 'Rotschwanz'


The hydrangea 'Rotschwanz', part of the Teller Series, is a striking ornamental shrub known for its large, flat flower heads. The blooms present a captivating mix of colors, typically ranging from deep pink to violet, and sometimes bearing shades of blue, depending on the soil acidity. Each flower head is a mosaic of smaller florets that have a star-like quality, with the outer ring of florets being significantly larger and showier than the tiny buds at the center. These outer florets tend to have a more pronounced color, while the inner buds might have a subtler hue. The leaves of the hydrangea 'Rotschwanz' are glossy, offering a deep green backdrop that contrasts beautifully with the vibrant flowers. They have a typically ovate shape with somewhat serrated edges, which adds texture to the plant's lush foliage. The overall impression of the plant is one of robustness and abundance, as it displays its striking blooms and rich foliage throughout its blooming season, which generally spans from early summer to late fall, offering a long-lasting display of color in the garden.

As needed
  • water dropWater

    Lacecap hydrangeas, including 'Rotschwanz,' typically require consistent moisture to thrive, so water them thoroughly to keep the soil moist but not waterlogged. During the growing season, water about 1 gallon per plant each time you water, ensuring that the water penetrates deeply into the soil. Generally, watering once or twice a week should be sufficient, but adjust based on weather conditions, with more frequent watering necessary during hot, dry periods and less when rainfall is abundant. In winter, reduce watering, but don't allow the soil to become completely dry.

  • sunLight

    Lacecap hydrangeas, such as 'Rotschwanz,' grow best in partial shade with some morning sun and afternoon shade, especially in hotter climates. The ideal spot shields them from the harsh midday sun, which can cause leaf scorch and stress the plant. A location with dappled sunlight throughout the day is also suitable, as this provides a gentle and consistent light source without the extremes of direct sunlight or deep shade.

  • thermometerTemperature

    Lacecap hydrangeas, including the 'Rotschwanz' variety, prefer moderate temperatures and perform well in a range between 60 to 75 degrees Fahrenheit. They can withstand minimum temperatures down to about 20 degrees Fahrenheit, but frost can damage new growth, so late spring frosts can be a concern. During the hottest parts of summer, providing extra shade can help protect the plant from extreme heat above 80 degrees Fahrenheit.

  • scissorsPruning

    Lacecap hydrangeas, including 'Rotschwanz,' benefit from occasional pruning to remove dead wood and encourage blooming. They bloom on old wood, so prune just after flowering in summer or in early fall to avoid cutting off next year's buds. Prune out any dead or weak stems to improve air circulation and overall plant health. Avoid heavy pruning unless necessary to rejuvenate an older plant; even then, do so immediately after flowering.

  • broomCleaning

    As needed

  • bambooSoil

    Lacecap hydrangeas thrive in well-draining, fertile soil with high organic matter. A mix of peat moss, compost, and perlite in equal parts is ideal. Maintain a soil pH of 5.5 to 6.5 for vibrant flower color.

  • plantRepotting

    Lacecap hydrangeas should be repotted every 2-3 years to refresh the soil. Larger specimens may need less frequent repotting if top-dressed with fresh compost.

  • water dropsHumidity & Misting

    Lacecap hydrangeas prefer moderate to high humidity levels, ideally around 50-60%. They tolerate lower humidity but flourish with higher moisture in the air.

  • circleLife cycle

    Hydrangea macrophylla 'Rotschwanz', commonly known as Bigleaf Hydrangea, begins its life cycle as a dormant, bare-root specimen or as a rooted cutting. Upon planting, it enters a vegetative growth stage characterized by the expansion of leaves and the development of a robust root system. The next stage is the flowering period, which typically occurs in early to mid-summer, showcasing large, showy flat-topped flower heads that start off as one color and often change as they mature, with this variety featuring red to violet florets. Following pollination, which is less significant for ornamental value in Hydrangeas, the plant may produce small, inconspicuous seeds, though many cultivated varieties are propagated through cuttings rather than seeds. As temperatures drop in autumn, the hydrangea enters a period of senescence where the leaves may change color before the plant becomes dormant in winter. Yearly pruning during late winter or early spring is crucial for removing spent flowers and encouraging new growth, thereby completing its annual cycle and preparing it for the succeeding season of growth and flowering.

      Spring-Early Summer

    • Hydrangea macrophylla 'Rotschwanz', commonly known as the Teller Series Hydrangea, is most effectively propagated during the warmer months of late spring through summer when the plant is actively growing. The most popular method of propagation is through softwood cuttings. To undertake this method, a gardener should cut a 4 to 6-inch (10 to 15 cm) piece of a healthy, new growth stem just below a leaf node. It’s essential to remove the bottom leaves and possibly dip the cut end in rooting hormone powder to enhance root development. The cutting should then be placed in a well-draining potting mix, ensuring at least one node is below the soil surface where roots will form. The environment should be kept humid, often by covering the cutting with a clear plastic bag or container, and kept out of direct sunlight. Roots typically begin to form within a few weeks, after which the new hydrangea can be gradually acclimated to less humid conditions and eventually planted out.
