Double Clematis Clematis 'Purpurea Plena Elegans' (Vt/d)

Water

Clematis 'Purpurea Plena Elegans', commonly known as Viticella Clematis, requires consistent moisture but does not like to be waterlogged. During the growing season, it should be watered deeply once a week with about 1 gallon of water per plant. In periods of drought or extreme heat, watering frequency should increase to twice a week, ensuring the soil remains moist but not saturated. During winter or cooler months, reduce watering as the plant's water requirements decrease. Always water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases.

Light

Viticella Clematis thrives in a location where it receives about 6 hours of sunlight daily, with some shade during the hottest part of the day to protect the blooms. Ideally, the plant should be positioned in a spot where the roots are shaded or mulched but the vines can climb towards the light. This balance ensures healthy growth and plentiful flowering.

Temperature

The ideal temperature for Viticella Clematis ranges from 55°F to 75°F. While the plant can survive temperatures down to about 20°F, it is essential to provide some protection to the roots during winter freezes. During the hot summer months, Clematis can tolerate temperatures up to 85°F, provided they are not exposed to prolonged periods of intense heat without adequate moisture.

Pruning

Viticella Clematis should be pruned to encourage strong growth and flowering. Prune in late winter or early spring when buds begin to swell. This type of Clematis falls into Pruning Group 3, meaning it flowers on new growth, so it can be cut back to about 12 inches from the ground. Pruning not only shapes the plant but also promotes vigorous growth and more flowers. The best time for pruning is usually February or March.

Cleaning

As needed

Soil

For Double Clematis, the ideal soil mix is well-draining, rich in organic matter with a pH of around 6.5 to 7.5. Incorporate compost and a balanced fertilizer, and ensure adequate drainage to prevent root rot.

Repotting

Double Clematis typically doesn’t need frequent repotting and can be done every 3-4 years or when it outgrows its current pot. Spring is the best time for repotting to allow the plant to establish in the growing season.

Humidity & Misting

Double Clematis thrives in moderate humidity conditions; it doesn't require high humidity. Ensure good air circulation to prevent fungal diseases but avoid extremely dry environments.

Suitable locations

• Indoor

  Ensure bright indirect light, support for climbing, and consistent moisture.

• Outdoor

  Plant in partial shade with support for climbing, and mulch the base.

• Hardiness zone

  4-9 USDA

Life cycle

Clematis 'Purpurea Plena Elegans' (also known as Double Purple Clematis) starts its life cycle as a seed, which germinates in spring when soil temperature and moisture levels are suitable. The plant then enters a vegetative stage, producing long vines and leaves while establishing a root system. From late spring through early autumn, the Double Purple Clematis enters the flowering stage, showcasing its distinctive double purple flowers. After blooming, the plant sets seeds surrounded by feathery structures, which are dispersed by the wind for reproduction. During the winter, the clematis enters a dormancy phase, where growth pauses and the above-ground parts of some varieties may die back, while the root system remains alive. With the arrival of spring, the cycle resumes as new growth emerges from the buds on the woody stems or from the base of the plant for non-woody types.

Propogation

• Propogation time

  Late winter-early spring

• The Clematis 'Purpurea Plena Elegans', commonly referred to as Viticella clematis, is best propagated through layering, which is a popular method for this specific variety due to its straightforwardness and high success rate. The ideal time to carry out this method is in late winter or early spring, just before the plant resumes active growth. To propagate by layering, select a long, healthy stem and gently bend it towards the ground. Make a small incision or notch on the underside of the stem where it naturally touches the soil to encourage rooting. Then, secure this portion of the stem in contact with the soil using a U-shaped pin or a heavy object, and cover it with about 2 inches (about 5 centimeters) of soil while ensuring that the tip of the stem is exposed. Over time, roots will develop at the point of contact with the soil. Once a good root system has been established, which can take several months, the new plant can be cut from the parent plant and transplanted to a desired location.
