clematis 'Mrs George Jackman'


Clematis 'Mrs George Jackman' is an ornamental plant known for its showy flowers and climbing habit, often used to adorn trellises, walls, or fences. This variety showcases large, impressive blooms that are particularly eye-catching due to their color and form. The flowers are white to slightly cream-colored, with a satin-like sheen on their broad petals. At the center of each flower, there is a striking contrast with a group of delicate, slightly fuzzy-looking structures that emanate a creamy or pale yellow shade. These blooms are star-shaped, with their petals unfurling elegantly from a central point. The leaves of this plant have a green shade, providing a lush backdrop for the flowers. They are divided into leaflets, often in groups of three, presenting a toothed or somewhat jagged edge which adds texture to the foliage. The foliage arrangement contributes to a dense, green coverage over the structures that the plant climbs on. This climber wraps its tendrils around supports, which enables it to reach upwards and spread, creating a vertical element of beauty in the garden. The contrast between the green leaves and the white to cream-colored blooms makes Clematis 'Mrs George Jackman' a sought-after choice for gardeners looking to add a touch of elegance to their outdoor spaces. Its blooming period adds to its appeal, as it brings vibrant life to gardens when many plants may not be at their peak display.

    The Clematis 'Mrs George Jackman', commonly known as Jackman's Clematis, should be watered thoroughly once a week during its growing season, ensuring that the soil is moist but not waterlogged. In the hot summer months, you may need to water more frequently, especially if the top inch of soil feels dry to the touch. Provide about 1 gallon of water per plant for each watering session. During the winter months or dormant period, reduce watering to every few weeks, just enough to prevent the soil from drying out completely.

  • sunLight

    Jackman's Clematis thrives in a spot that has full sun to part shade. The ideal location would be one where the plant receives at least six hours of sunlight a day but is shielded from the intense heat of the afternoon sun. This will ensure it gets the light it needs without suffering from potential heat damage.

  • thermometerTemperature

    The ideal temperature range for Jackman's Clematis is between 50 and 75 degrees Fahrenheit. This plant can survive winter temperatures as low as 20 degrees Fahrenheit but may need some protection from extreme cold. During the hottest parts of summer, temperatures exceeding 90 degrees Fahrenheit can stress the plant, so some shading may be beneficial.

  • scissorsPruning

    Jackman's Clematis should be pruned to encourage vigorous growth and to maintain a desirable shape. Pruning should be done in late winter or early spring before new growth begins. This plant falls into Pruning Group 2, where light pruning to remove dead and weak stems is recommended, and cutting back to strong buds is done every year.

  • circleLife cycle

    Clematis 'Mrs. George Jackman' initiates its life cycle when its seeds germinate, preferring well-drained soil and partial shade to full sun conditions. After germination, the seedling develops into a young plant, establishing a strong root system and beginning to send out vines. As it matures, the clematis produces long, climbing stems which require support, and it can be trained on trellises, fences, or arbors. In late spring to early summer, the plant enters its flowering stage, displaying large, showy white flowers with creamy or slightly greenish stamens. Following pollination, the clematis sets seed, producing feathery, plume-like seed heads that can be distributed by wind. The plant then enters dormancy in the colder months, often dying back to the ground in freezing climates, to re-emerge and repeat its growth cycle in the spring.

      Early spring

    • The Clematis 'Mrs. George Jackman', commonly referred to as clematis, is most commonly propagated by layering or taking semi-hardwood cuttings during the summer months. To propagate by layering, one needs to select a healthy, flexible stem and gently bend it towards the ground. A small section of the stem is scraped to expose the inner tissues and then pegged down into the soil, sometimes with the aid of a rooting hormone to encourage root development. The layered section should be kept moist and is typically left in place until the following spring, at which point it will have developed roots and can be severed from the parent plant and transplanted. This method is popular as it retains the characteristics of the parent plant and does not require as much care as cuttings might.
