The Clematis Vines or the Queen of the Vines is commonly known for its beautiful and showy flowers. Despite having such grandeur, the most common misconception about them is that they are high maintenance and hard to grow. The truth of the matter is that this Queen does not need fancy things and lives simply.
Belonging in the Ranunculaceae family, the Clematis sp goes by many names such as Clematis Vines, The Queen of the Vines, Leatherflower, Traveller’s Joy, Vase Vine, Virgin’s Bower, Leather Flower, and Old Man’s Beard. There are over 250 species and thousands of varieties of this plant as it is widely used in the landscape due to its aesthetic appeal and growth habits.
It was first seen in Japan, China, India, Australia, New Zealand, Europe, and North America. Generally, the Clematis plants grow in temperate regions and bloom better in places with the same climatic conditions. Given its origins, the Clematis Vine thrives in USDA Zones 3 to 9.
The Clematis Vines are deciduous and evergreen broadleaf consists of leaves that are somewhat common to other people’s eyes. They are green and glossy, sometimes characterized as leathery as well.
Depending on the species, their leaf shapes may vary from cordate, lanceolate, elliptical, or deltoid, as well as their leaf margins. It can be either toothed or not. Their leaves are arranged in alternating positions and trichomes are not present.
As beautiful as the Clematis flowers may look, the colorful parts are not petals but sepals. Since this genus has hundreds of species and thousands of varieties, flower shapes and colors vary from bell-shaped, tulip-shaped, tubular, open bell-shaped, star-like, double, semi-double, or single, composed of 4 to 20 petal-like sepals. Usually, it extends to 3 inches in diameter but some can go as wide as 8 inches.
At the fruit set, flowers slowly dry and produce achenes or small dry fruits with a silky hair-like tail. Usually, the seeds are brown to a golden brown.
Growth and Development
Despite being called the Queen of the Vines and having the appearance of expensive and high-maintenance plants, the Clematis plant is an aggressive grower and requires less maintenance than other high-value plants. Due to its climbing nature, the plant easily clings and grows with the help of other structures such as trellises.
Also, they have the ability to adapt to their environment quickly because of their tendrils. These are specialized structures that serve as an anchorage for the plant as it grows toward places with more sunlight. It can grow as high as 30 to 50 feet, given the right support.
Different species of the Clematis Vines are classified based on their blooming patterns and, in turn, maintenance schedules are planned after. Aside from the pruning schedules, other caring methods for most species are similar.
When selecting clematis companion plants, consider plants with contrasting colors or complementary foliage, as well as having similar growing conditions.
Clematis Care and Growing Tips
These vines are sun-loving and should be exposed for at least 6 hours uninterrupted for them to bloom. Although there are varieties that tolerate being planted on shaded areas, such as Alba Luxurians, Purpurea Plena Elegans, and Betty Corning. The mentioned varieties may have smaller flowers than others but it is good for people who are new to gardening and have no full-sun areas to plant.
In the first year of growth, it is necessary to ensure that the soil is moist throughout the growing season. This can be achieved by watering every week, once or twice a week. Remember to observe the plant and the soil for signs of dryness or overwatering, too much or too little moisture may cause detrimental effects for the Clematis Vines.
Clematis vines are perennials and they love to grow in one spot for long periods. Hence, it is important to choose the best planting spot for them. Ideally, the soil should be loamy and rich in organic matter. The root zone should be kept in an area that has a lower temperature. Some soils tend to lose more moisture than others, especially on hot days. Therefore, adding mulch, such as leaves, compost, or coco peat, inches from the stem will help retain moisture.
The leaves and the roots differ in temperature requirements. The leaves want to be exposed to the full sun most of the time, resulting in higher temperatures, while the roots prefer to be in a cooler place.
The beauty Clematis brings comes with a cost, in this case, it is the soil nutrients. These vines are known to be heavy feeders. In line with this, the application of complete fertilizers may be done monthly during the growing season. Altering the fertilizer to be supplied to a more phosphorus-rich fertilizer should be done during the flowering season. Failure to do this change may affect the flowering which may result in fewer blooms.
Pruning clematis is the most important maintenance activity for these vines and it should be coherent to what type you are planting. Below are the different groups classified based on their time of flowering. Along with each group is how pruning should be done.
These are Clematis plants that bloom after it has matured in the previous season. The best way to prune is by removing dead and weak parts. Letting the plants fully bloom during spring before making any extensive pruning is advisable. Usually, heavy pruning may be done during early summer or late spring to give the plant enough time to regenerate for the next season.
Under this classification are clematis plants that can produce flowers on both new and old growth. June is when the first peak of flowering occurs and will repeat at the latter part of the season. Heavy pruning is not recommended in this group. Light pruning or removal of dried, dead, and damaged parts should be performed after the first peak of bloom, helping the plant create more blooms in the late parts of the season.
Under this group are the species and varieties of Clematis that bloom on new growth and can withstand extensive pruning as it helps in the continuous production of flowers around the latter half of summer or early fall. Pruning for this group is best performed during spring. Aside from the usual removal of dead, dried, and damaged plant parts, pruning 6 to 12 inches of older stems will give way to younger shoots and rejuvenate the plant.
Clematis reproduces either through seeds, but young stem cuttings are the common way of propagation. Choosing the right planting material is crucial in this type of propagation. Stems that are not too mature or too young to develop roots.
After choosing the right stem cuttings to plant, preparing the right rooting media using soil that is rich in the organic matter should be done. Plant the stem around 3 inches deep with the crown of the plant on the top part.
Remember that watering deeply is crucial to develop a strong root system for the clematis. The amount of water may be changed to at least an inch deep after a year of growth.
After the cuttings are established, transplanting should be done on a carefully chosen spot in your garden or landscape. Follow the mentioned recommendations for caring mentioned above.
Problems Frequently Encountered
The Clematis Vines usually encounter powdery mildew and wilt. This can be identified if there are fungal spores on surfaces of the plant that are browning or wilting. Fungal diseases are controlled by removing the infected parts and application of fungicides to protect those that are not infected yet. To avoid plant diseases, ensure proper keeping and sanitation of garden tools and selecting disease-free planting materials.
