Water

The Clematis Cézanne should be watered deeply once a week, ensuring moisture reaches the roots, which typically equates to about one gallon of water per session. During hot or dry spells, increase watering frequency to twice per week. It’s important to avoid overhead watering to prevent disease; instead, water at the base of the plant. Reduce watering in the fall and winter when the plant is dormant, adjusting as necessary to keep the soil from drying out completely.

Light

Clematis Cézanne thrives in a location that receives full sun to partial shade. Ideally, situate the plant so that its roots are shaded, either by other plants or a mulch layer, while the foliage and flowers receive at least six hours of sunlight daily. Too much shade can reduce blooming, so aim for a balance of morning sunlight and afternoon shade if possible.

Temperature

Clematis Cézanne performs best in temperatures between 60°F and 75°F. It can withstand short periods of colder weather down to about 20°F but should be protected from severe cold snaps. In regions where the temperatures frequently drop below this range in winter, adding a layer of mulch for insulation is advisable.

Pruning

Pruning encourages healthy growth and prolific blooming in Clematis Cézanne. Prune it in late winter or early spring, removing any dead or weak stems. This variety typically blooms on new wood, so annual moderate pruning will enhance the plant's performance. Aim to cut the plant back to about a foot from the ground at this time. Additionally, deadhead spent blooms throughout the growing season to encourage more flowers.

Cleaning

As needed

Soil

Clematis 'Cézanne' thrives best in well-draining, loamy soil with a pH of around 6.5 to 7.5. To create an optimal soil mix, blend garden soil with compost and a bit of perlite or grit to improve drainage. Mulching around the base with organic material can help retain moisture and keep roots cool.

Repotting

Clematis 'Cézanne', a perennial vine, typically does not require frequent repotting. It may be repotted every few years to refresh the soil or if the plant has outgrown its current container. However, ensure it's done during the dormant period, which is late winter or early spring.

Humidity & Misting

Clematis 'Cézanne' appreciates a moderate level of humidity but is tolerant of average outdoor humidity levels. It does not have specific humidity requirements, but ensuring good air circulation around the plant can prevent fungal diseases.

Suitable locations

• Indoor

  Place in a bright spot, with some direct light, and keep soil moist.

• Outdoor

  Plant in fertile, well-drained soil with partial to full sun.

• Hardiness zone

  4-9 USDA

Life cycle

Clematis Cézanne, commonly referred to as Clematis, begins its life cycle as a seed that germinates when conditions are favorable, typically requiring a period of cold stratification. Once sprouted, the seedling grows, developing a robust root system and climbing stems with leaves. As it matures, Clematis Cézanne produces flower buds in late spring which bloom into large, colorful flowers throughout summer and often into early autumn, attracting pollinators. After pollination, the plant forms seed heads that disperse seeds, allowing for the cycle to start anew. During the winter, it enters a period of dormancy, conserving energy and resources, sometimes with the above-ground growth dying back, depending on the climate and specific variety. With the return of warmer temperatures in spring, the Clematis resprouts from its rootstock or remaining stems, beginning the cycle again.

Propogation

• Propogation time

  Early spring

• The Clematis Cézanne, which goes by the scientifically annotated name 'Evipo023' (PBR) (EL), is commonly propagated through cuttings, a practice widely advocated for many in the Clematis genus. The most effective time to take semi-hardwood cuttings is during late spring or early summer, when the plant is actively growing and healthy material is abundant. To propagate Clematis Cézanne by cuttings, locate a strong, healthy stem and make a cut to create a segment around 4 inches (about 10 centimeters) long, ensuring at least a couple of sets of leaf nodes are present. The lower leaves are removed, and the cut end can be dipped in a rooting hormone to increase the chances of successful rooting. This cutting is then placed in a well-draining potting mix and kept in a humid environment until roots develop, which can take several weeks. Patience is vital, as clematis can be slow to root, but maintaining the right conditions will give these cuttings the best chance to develop into healthy new plants.
