Initially, after planting, water the plant about two to three times a week to ensure the soil remains moist but not waterlogged. Once established, reduce watering to once a week, providing about 1 gallon of water each time, depending on weather conditions. During hot, dry spells, it may require more frequent watering. Always check the top inch of the soil before watering; if it's dry, it's time to water.

    Clematis 'Rubromarginata' thrives best in conditions where it can receive at least six hours of sunlight daily.

  • circleLife cycle

    Clematis × triternata 'Rubromarginata', commonly known as clematis, begins its life cycle as a seed which, when sown in the soil, germinates given adequate warmth and moisture. Once germination occurs, the seedling emerges and develops its first true leaves, entering the vegetative growth stage where the plant increases in size and produces more leaves and stems. As the clematis matures, it enters the flowering stage, wherein it develops buds that bloom into fragrant flowers with purple-pink margins, typically in the summer. After pollination, often by bees and other insects, the flowers give way to seed heads, which contain the seeds for the next generation. As the growing season ends, the clematis may enter a dormant period, especially in colder climates, where it conserves energy by dropping leaves and slowing down growth. With the return of warmer temperatures in spring, the plant breaks dormancy, resuming vegetative growth and preparing for another cycle of blooming.

      Late winter to early spring

    • Clematis × triternata 'Rubromarginata', commonly known as Virginsbower, is typically propagated through softwood or semi-hardwood cuttings, a popular method carried out in late spring or early summer. To propagate by cuttings, a gardener would select a healthy piece of stem about 4 to 6 inches (around 10 to 15 centimeters) long. The cutting should have at least two sets of leaves and be taken just below a node, the point on the stem where leaves are attached. The lower leaves are removed, and the cut surface may be dipped in rooting hormone powder to encourage root development. The prepared cuttings are then placed in a well-draining soil mix, keeping the humidity high and the soil consistently moist. In a few weeks, with proper care, which includes keeping them warm and shaded from direct sunlight, the cuttings can develop their own root system and be ready for transplanting.
