Blue-Purple Clematis Flowers with Creamy White Stamens
What are Clematis Varieties?
Clematis varieties are classified as tender vine or evergreen and pruning group of plants. Apart from vine or climbing clematis varieties, bush varieties also exist. The flowering plants can beautify gardens in beautiful colors and are available in diverse colors, forms and complexity.
Due to their varying bloom sites, clematis varieties are pruned based on class. Furthermore, vine and bush varieties require different support during growth. Therefore, gardeners should know their plants and specific varieties in their gardens to accord them the right support.
Classes of Clematis Varieties
The class of clematis varieties determines the kind of care specific plants require. Whereas class 1 clematis varieties bloom off mature wood, class 2 varieties bloom off mature and new wood, flowering two times in a single season. On the other hand, class 3 clematis varieties bloom off budding wood.
Knowledge of the right class ensures clematis varieties are pruned at the right time. Otherwise, the wood flowers bloom off might be cut off before the flowering season. Trimming a minimum of two vines can help determine the class of plants whose class is unknown.
Forms of Clematis Varieties
Climbing clematis vines are popular among gardeners. Bush clematis varieties grow upright as shrubs up to 3 feet based on species. They include Tube, the Mongolian Snowflakes and Fremont's clematis. Rock or trailing clematis has vines that crawl on the surface of soil, creating appealing soil cover.
Trailing clematis varieties include the Mongolian Gold, Ground and Sugarbowl. Some climbing clematis varieties are not just easy to grow, but also attractive. For instance, C. macropetala has beautiful blue flowers that grow up to 5 inches wide. On the other hand, Bees Jubilee feature mauve blooms.
Magenta C. viticella 'Grandiflora Sanguinea' and Crimson Ville de Lyon make landscapes more vibrant.
Pink-Purple Clematis Flowers
Evergreen Clematis Varieties
Just like deciduous plants, evergreen clematis varieties require cultural care. The persistent, arrow-shaped leaves are glossy and vibrant, creating accents and vibrant shields. The plants bloom in early spring towards the end of winter. The plants do well in temperate climates. It is among the first vines to produce flowers.
A good example is Armand's clematis varieties with white blooms and a great scent. The plant belongs to the class or group 1 clematis varieties. Climbing clematis vines require support and training.
Yellowing of Clematis Leaves
Clematis varieties are tolerant of various conditions upon maturity. However, insufficient nutrients in soil and infestation of pests can cause the leaves to yellow. Diseases such as mites, weather, pests and poor cultivation conditions such as site, soil and drainage, and lighting can cause clematis leaves to yellow.
Clematis varieties for full sun require at least six hours of full sun to bloom while clematis varieties for shade are protected at the base or mulched to prevent loss of moisture. They thrive in well-drained, fertilized soils with compost to improve nutrients, drainage and flow of air.
Magnesium and iron deficiency causes yellowing of clematis leaves. The latter increases soil pH while the former is fixed using a mixture of one gallon of water and a teaspoon of Epsom salts. The mixture is applied once a week to give the leaves back their green color.
How Long Clematis Varieties Take to Bloom
Clematis varieties are perennial vines that brightly bloom in cascades of colors for many years. Different varieties bloom at different times and for varied duration. Depending on the variety, clematis flowering plants can bloom in spring, autumn, summer or across different seasons.
Clematis varieties can also bloom in two different seasons or periods. USDA zone, sunlight and the quality of soil can affect a variety's bloom time.

Summer Blooming Clematis Varieties
Clematis is a showy and versatile vine. The shape and size of flowers vary from cultivar to cultivar. A combination of spring, winter and summer clematis varieties in the same garden can ensure it blooms all-year round.
Although spring blooming clematis varieties are the most common, interesting varieties in flower and vine cascades can ensure a garden blooms into fall. Summer varieties can bloom in June and July or into autumn. They can either be non-vining or vining types of clematis. Despite being colorful, each has a distinct growth habit
- Non-Vining Summer Clematis
The bushy yet compact nature of non-vining clematis plants that bloom in summer makes them ideal for perennial or container gardens. Tube clematis (funnel-shaped blue flowers), solitary clematis (large, lavender flowers) and Mongolian Gold (cold and drought tolerant; deep yellow flowers) are non-vining summer varieties.
- Vining Summer Clematis Varieties
Vining clematis varieties climb and thus need support. They include Durand (lavender blue flowers), Elsa Spath (bigger flowers), Sweet Autumn, Jackmani, and Henryi.
Other Summer Clematis Varieties

Clematis Plants Care and Cultivation
Clematis varieties are the most attractive and popular flowering vines for home gardens. They can be deciduous, woody, evergreen or herbaceous. Although most varieties bloom from early spring to fall, varieties vary in color, form and flowering seasons. However, growth requirements for most plants are similar.
Clematis vines require at least 6 hours of sunshine and cool, moist soils for the roots. Two inches thick mulch or a cover crop can help keep the soil cool and moist. Most clematis varieties use fences or trellis for vine growth support. However, larger varieties grow up to 12 feet tall and thus require arbors for support.
Smaller vine varieties grow up to 5 feet tall; they can use poles as vine support systems. The vines are planted in early spring or fall depending on variety and climatic region. They can be planted in gardens or containers. The vines do well in rich, well-drained soils and require proper spacing for sufficient air flow between plants.
Holes should be dug at least 2 feet deep and soil mixed with compost. Before planting, the vines are pruned to minimize shock while enhancing adaptation to the new growth environment. The plants are watered weekly and mulch replaced every spring.
Control diseases such as powdery mildew and clematis wilt, and pests such as spider mites and aphids. Prune clematis based on variety to promote growth and flowering while enhancing the plant's attractiveness. Large-flowering clematis varieties flower in mid spring; prune them in early spring or late winter and cut only the buds at the top.
Prune the early-spring-blooming clematis varieties prior to July but after the plants flower. The plants bud on the growth from the last season. On the other hand, prune late-blooming varieties in early spring or late winter; only cut the buds at the top. Use winter bags to overwinter clematis varieties in winter; it involves deadheading clematis and plant protection from freeze-thaw-freeze cycles.
Grow Clematis Vines in Pots/Containers at Home
Unlike vines grown in gardens on the ground, potted clematis plants need more care and attention. Potted clematis plant varieties include the Polish Spirit (blue-purple flowers), Nelly Mosser (purplish-pink flowers), Sieboldii (purple-creamy-white flowers; dwarf varieties) and The President with red flowers.
Grow clematis plants in large fabric pots, especially for winter when clay or ceramic pots tend to crack. Water the potted plants as recommended or as need be.
