These plants dress up any kind of structure they climb with their flowers that come in an array of shapes and colors. Bloom time ranges from late spring to fall, depending on the type and variety. With a little planning, it’s possible to have clematis blooms in your garden throughout the growing season. You can even plant these vigorous vines alongside sturdy woody plants such as roses, trees, or shrubs to act as a living trellis. David McDonald. David McDonald Whether it's a summer-blooming variety with large, showy blooms, or a fall-blooming type of clematis with hundreds of smaller flowers, these vines make a stunning statement. The most common clematis are the open-face blooms that reach as large as 7 inches across. Blooms also come in small, bell-shaped blossoms with outer petals that dangle like little lanterns. Some blooms have a pleasant fragrance. The swirling masses of fluffy seeds add textural interest, too. Bloom time of clematis vines varies, depending on the species. Many new varieties are rebloomers, but most of the older types will only bloom for one season. However, even after blooming, clematis flowers add interest. As the seed heads mature, they expand to become fluffy balls that look especially pretty in dried floral arrangements.

If you suspect your child has eaten clematis, call the doctor. The plant is also known to be toxic to dogs, cats, and horses. Where to Plant Clematis Clematis is a perennial vine that grows in USDA Hardiness Zones 4–9. It thrives in the garden or planted in containers. Although most clematis plants are vining types, there are some shrubby clematis varieties available. Invasive Plant Some clematis varieties can become invasive, so deadhead blooms to prevent their spread. Clematis Care Tips Clematis is an easily grown perennial vine, as long as you keep a few things in mind. Light In general, clematis prefers full sun, but a few varieties can manage to grow in partial shade. An important thing to note: Although the leaves of the plant thrive in the warm sunlight, clematis prefers to have cool roots, so plant it at the base of another plant that will provide shade over the base of the plants. Soil and Water A clematis prefers well-drained soil and consistent moisture. Certain species are more drought-resistant and can handle dry soils better than others. Fertilizer Clematis has a reputation as a heavy feeder, so don't neglect regular fertilization. Begin in the spring after the buds form and use a low nitrogen fertilizer (5-10-10). Continue to feed the plant every four weeks or so throughout the season using a balanced 10-10-10 fertilizer. Pruning Pruning clematis vines is quite simple. There are three main classes when it comes to pruning, numbered accordingly. The group numbers indicate how to prune. To start, no matter which group number vine you have, it's always a good idea to give plants in their first year a good spring pruning. Group 1 plants will bloom on old wood (growth from previous seasons), so if needed, prune them right after blooming. Clean up these vines lightly in early spring, but be aware that any live growth you remove is, in fact, a potential flower you've just cut. Try to only cut off dead wood. Here’s When to Prune Trees, Shrubs, and Flowers for Healthier Plants Group 2 vines bloom on both new and old growth. Typically, most of their blooms will appear in spring, but they'll also put on another floral show on new growth in the fall. With this group of clematis, you can do some mild pruning in early spring, especially removing dead wood. Any major work should be done just after the primary bloom in spring. Group 3 vines all bloom only on new wood. These types of clematis vines are easy to grow and can be cut back every spring to about 8-12 inches above the ground. If you don't cut Group 3 back each spring, plants can become overgrown and unruly. How to Propagate Clematis You can propagate clematis with seeds by planting them in a flat of seed-starting mix and keeping it moist, but it can take several months before you see any results. Taking softwood stem cuttings from a healthy plant in April or May is a better method for propagating clematis. The cutting must contain a leaf bud. Press the cuttings into a small pot filled with compost or seed-starting mix, water, and cover with a plastic bag. When they root, transfer them to separate containers. It can take as long as a year for the seedlings to be robust enough to be planted outdoors.

Yes, although the vining types are difficult to work with; use those trailing from the bottom of an arrangement. Choose the blooms of shrubby or herbaceous types of clematis for your arrangements if possible because their stems are rigid and easier to work with. Does clematis attract pests or have diseases? Clematis wilt is a fungus that affects some large-flowered clematis plants. The plant is also susceptible to common garden pests, such as aphids, scale, spider mites, and slugs.
