    For Lacecap Hydrangeas, which is a common name for Hydrangea macrophylla varieties including 'Mariesii Lilacina', it's essential to maintain moist but well-draining soil. Water these hydrangeas deeply once a week, providing about 1 gallon of water per plant, especially during dry spells. During periods of extreme heat or drought, check the soil moisture more frequently and increase watering as needed to ensure the soil doesn't dry out, but avoid waterlogging. In the fall, reduce watering to help prepare the plants for dormancy. Remember to water directly at the base of the plant to keep moisture off the leaves and flowers.

  • sunLight

    Lacecap Hydrangeas prefer a location with morning sun and afternoon shade, which helps protect the blooms from intense midday heat. Ideally, provide these hydrangeas with about 4 to 6 hours of filtered sunlight per day, which can be achieved by planting them in a spot that gets dappled shade under a canopy of deciduous trees or on the east side of a building.

  • thermometerTemperature

    Lacecap Hydrangeas thrive in a temperature range between 60°F and 80°F, making them suitable for most temperate climates. They can tolerate minimum temperatures down to around 20°F; however, winter protection may be needed to prevent frost damage. The optimal growth temperature for 'Mariesii Lilacina' occurs within the 65°F to 75°F range, where the plant can flourish without stress.

  • scissorsPruning

    Lacecap Hydrangeas benefit from pruning to remove dead wood and to shape the plant, typically done in late winter or early spring. Since 'Mariesii Lilacina' flowers on old wood, be cautious not to remove stems that will produce the current year's blooms. Prune immediately after flowering if needed to encourage vigor and maintain a desirable size, but avoid extensive pruning late in the season.

  • circleLife cycle

    Hydrangea macrophylla 'Mariesii Lilacina', commonly known as Lacecap Hydrangea, begins its life cycle with seed germination, which typically occurs in spring when soil temperature and moisture levels are suitable for growth. Following germination, the seedling stage involves the development of the first true leaves and establishment of a root system. As the plant enters the vegetative growth stage, it develops a woody stem, more complex root system, and larger leaves, preparing for flowering. During the flowering stage, which usually occurs in early to mid-summer, the Lacecap Hydrangea produces distinctive flat flower clusters with small fertile florets surrounded by larger sterile florets, often exhibiting shades of blue or pink depending on soil pH. After pollination and fertilization, the plant develops seeds within the spent flowers as it progresses into the senescence stage, preparing for dormancy during the winter months. The plant can then survive winter dormancy, re-emerging and repeating the cycle in the following spring.

      Early spring

    • Hydrangea macrophylla 'Mariesii Lilacina', commonly known as Lacecap Hydrangea, is commonly propagated by softwood cuttings taken in late spring or early summer when the plant’s new growth is still tender and flexible. To do this, a gardener should select a healthy branch and cut a 4 to 6 inch (10 to 15 cm) portion that includes at least two pairs of leaves. The lower leaves are removed, and the cut end is often dipped in rooting hormone to improve the chances of root development. This prepared cutting is then inserted into a pot filled with moistened potting mix, sand, or vermiculite. It’s crucial to keep the cuttings under conditions of high humidity and indirect light until roots develop, which typically takes 2 to 4 weeks. Once rooted, the young plants are potted into individual containers to grow on before being planted out the following spring.
