As climbers, Clematis are unsurpassed in their long flowering presence, the rich diversity of flower shapes, a wide array of colors, and tolerances in terms of exposure and climate. It is no wonder they are so popular! From tree huggers to container varieties, there is a Clematis for every garden and flowers for almost every month of the year!

Members of the Ranunculaceae family, Clematis, include more than 300 species and hundreds of hybrids and are divided into 12 main groups, each with consistent flower size, blooming season, pruning and garden use characteristics.

Clematis – Late Large-Flowered Group

The small-flowered Orientalis group contains the truly yellow clematis. Mostly originating from Central Europe and Asia, this group comprises clematis species such as Clematis orientalis, Clematis serratifolia, Clematis tangutica, or Clematis tibetana. Used to harsh conditions in their native environment, these vigorous clematis enjoy so much our temperate conditions that some have ended up on invasive or noxious plant lists.

  • Habit and Size: Strong-growing, these clematis are deciduous vines or scrambling shrubs that grow rapidly, with at least three feet (90 cm) of growth per year from sprouts or existing stems. They can reach 15-20 feet (4.5-6 meters). These plants are true climbers and prefer a structure or support to twine their leaf stalks around.
  • Foliage: Foliage is often mid-green and provides a nice backdrop for the vibrant flowers.
  • Flowers: Their bright yellow flowers are small, lantern- or star-shaped, and often nodding. Each flower produces showy pom-pom-like seedheads with silvery silken tails that persist and disperse over the winter and early spring.
  • Blooming Season: They bloom profusely from mid-late summer to fall and appear particularly conspicuous in autumn when color has disappeared elsewhere in the garden.
  • Hardiness: Hardiness is generally strong, with most varieties thriving in USDA zones 4-11.
  • Uses: These Oriental clematis can be trained over arbors, pergolas, or fences. They partner well will the biggest rambler roses and create a stunning effect in conifers that tolerate some companionship.
  • Pollinators: Clematis attract bees and other pollinators, providing a valuable resource in the garden.
  • Deer and rabbit: They are also not a favored food source for deer or rabbits.
  • Toxicity: All parts of the plant are toxic if ingested and can cause skin irritation. Toxic to cars, dogs, and horses.

Favorite Oriental Clematis

Growing the Clematis Orientalis Group can be quite rewarding with the right care. Here are some tips to help these vines thrive:

  • Sunlight: Plant your Clematis in a location where it can receive at least six hours of sunlight each day. However, they prefer the top of the plant in sun and the roots in shade. So, it’s often beneficial to plant it where the roots can be shaded by other plants or a layer of mulch.
  • Soil: These plants prefer well-drained, fertile soil. They can tolerate a wide range of soil types, but adding organic matter like compost can improve the soil’s structure and provide essential nutrients.
  • Watering: While Clematis Orientalis is somewhat drought tolerant, it will perform best with regular watering, especially during dry periods. Ensure the soil is moist but not waterlogged.
  • Pruning: This group belongs to pruning group 3. This means they flower on the current year’s growth and should be pruned in late winter or early spring. Cut back all the old stems to the lowest pair of healthy buds, about 6-12 inches from the ground. This hard prune will encourage the plant to put out lots of new growth and flower prolifically.
  • Support: Provide a trellis, arbor, or another climbing structure for your clematis to grow on. They use leaf-stalks to twine around structures and need something thin enough to wrap around.
  • Fertilizing: Feed your clematis with a balanced fertilizer in early spring, and again in mid-summer to promote blooming.
  • Diseases and Pests: Monitor for common pests like aphids and caterpillars, and fungal diseases such as clematis wilt. While not typically a significant problem for this group, a healthy plant is the best defense against these issues.

Remember, every garden and every plant can be unique, so use these tips as a general guide and adjust based on your specific conditions and experiences.
