WaterThe Clematis, commonly known as Virgin's Bower, should be watered regularly to maintain a moist, but not soggy, soil environment. During the growing season, it's typically recommended to provide the plant with about 1 gallon of water per week, adjusting as necessary for rainfall and temperature conditions. To avoid waterlogging and possible root rot, ensure that the soil drains well. It's best to water the plant deeply and infrequently rather than little and often, encouraging strong root development. In hot, dry weather, watering frequency may need to increase, while in cooler, wet periods, it may decrease.
LightVirgin's Bower thrives in a location that receives full sun to part shade. Ideally, the plant's base and roots should be shaded or mulched to keep them cool, while the foliage and flowering parts should have access to sunlight for at least 6 hours a day. A spot that offers morning sun and afternoon shade can be particularly good for preventing wilt in hotter climates.
TemperatureVirgin's Bower Clematis prefers a temperate climate and will thrive best in temperatures ranging from about 50°F to 75°F for optimal growth. These plants are typically hardy in zones 4 to 9, which means they can usually withstand minimum winter temperatures down to -30°F, and during the summer months, they can tolerate temperatures up to around 95°F.
PruningVirgin's Bower should be pruned to maintain shape, encourage vigorous growth, and promote more abundant flowering. It is often best to prune in late winter or early spring before new growth begins. Depending on the flowering group of your clematis (whether it blooms on previous or current year's growth), you may do a light prune just to remove dead and damaged stems or a harder prune to rejuvenate the plant. Prune again after the first flush of flowers to shape the plant and stimulate new blooms.
CleaningAs needed
SoilThe best soil mix for Clematis 'M. Koster', commonly known as Virgins Bower, is a well-draining loamy soil with good organic matter content. Aim for a soil pH between 6.0 and 7.0. You can create an ideal mix using two parts garden loam, one part well-rotted compost, and one part gritty material like perlite or coarse sand.
RepottingClematis 'M. Koster', or Virgins Bower, should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. Younger plants may need more frequent repotting while established plants can be left longer if they show no signs of stress.
Humidity & MistingClematis 'M. Koster', also known as Virgins Bower, prefers moderate humidity levels. While it does not require high humidity, ensuring the surrounding air is not too dry can help the plant thrive. Avoid overly arid conditions that can desiccate the foliage.

Life cycleThe clematis 'M. Koster', like other clematis plants, begins its life as a seed, which, when planted in well-drained soil and given adequate warmth and moisture, will germinate and sprout. The seedling stage follows, characterized by the development of the first true leaves, and as the plant matures, it enters the vegetative stage, where it produces a vine-like stem and more complex leaf structures. During the growing season, the clematis 'M. Koster' enters the flowering stage, displaying large, vibrant, purple flowers that attract pollinators. After pollination, the plant produces seed heads, which mature and eventually release seeds, completing the reproductive cycle. In the dormant stage, which occurs in the colder months, the above-ground parts of the clematis die back, while the root system remains alive to start the cycle anew in the spring. The clematis 'M. Koster' can live for many years, going through this yearly cycle, with older plants typically displaying more abundant and vigorous blooms.
PropogationPropogation time
Spring-Early Summer
The most popular method for propagating the Clematis 'M. Koster' is by taking softwood cuttings in spring as the plant begins to grow vigorously. To do so, choose a healthy shoot and cut a piece about 4 to 6 inches (10 to 15 cm) long, ensuring the cutting has at least two pairs of leaves or nodes. The lower leaves are removed, and the cutting is dipped in rooting hormone to encourage root development. The prepared cutting is then placed in a well-draining potting mix, ensuring the bottom node is buried in the soil. The pot should be placed in a warm, well-lit area but out of direct sunlight and kept consistently moist. Roots typically develop within a few weeks, after which the new Clematis can be gradually acclimatized to outdoor conditions and eventually transplanted to its final position in the garden.
