How to Grow
The foundation for a thriving Clematis ‘Evijohill’ JOSEPHINE begins with the soil and location preparation. Plant this vigorous Clematis in fertile, well-drained soil that retains medium moisture. While the vines themselves prefer full sun or partial shade, the roots must be kept cool and shaded; this is crucial for the longevity of any Clematis vine.
To achieve root cooling, site your Clematis where the flowering parts receive appropriate sunlight, but ensure the base is shaded by companion perennials, small shrubs, or a deep layer of mulch. Never permit the soil around the roots to dry out completely, as Clematis requires uniformly moist conditions, particularly during the heat of summer. All vining hybrids, including JOSEPHINE, need a trellis or another stable structure on which to twine and climb.
Pruning is vital for this variety; Clematis ‘Evijohill’ JOSEPHINE is classified as Group 2. Group 2 Clematis bloom on both old wood (last year’s growth) and new wood. Generally, extensive pruning is discouraged to maintain bloom volume, although light trimming in spring is acceptable. Avoid harsh pruning in fall or early spring, as this can reduce or delay flowering. Mulching the root zone heavily is highly recommended for insulation and moisture retention.
Landscape Uses
Clematis vines offer unparalleled vertical accents in the landscape, and Clematis ‘Evijohill’ JOSEPHINE excels at transforming plain surfaces. Train this vigorous climber up trellises, fences, arbors, or even lampposts to introduce architectural height quickly. Because of its dense, floriferous nature, it can function as a stunning focal point in cottage gardens or as an elegant screen.
For best results, pair the vibrant lilac-pink blooms with contrasting colors or textures. Consider planting evergreen shrubs near the base to maintain the necessary cool, shaded root conditions while the upper vine basks in the sun. This Clematis also works surprisingly well when allowed to sprawl over sturdy, short shrubs, creating a cascading floral effect rather than strictly vertical growth.
If space is limited, Clematis can be successfully grown in large containers, provided ample internal support is installed immediately upon planting. For border designs, use shorter, sun-loving perennials like hardy Geraniums or Hostas at the base of the trellis to keep the root zone shaded while complementing the mature height of this beautiful vine.

Noteworthy Characteristics
Clematis is a genus of over 250 species, most of which are woody to semi-woody deciduous vines climbing by twining leaf stalks or in some cases trailing over support, but in a few cases grow as freestanding or sprawling herbaceous perennials and small deciduous or evergreen shrubs. This specific cultivar, ‘Evijohill’, features large, dahlia-like, double flowers that create a substantial visual impact from late spring through summer. Cultivated plants, including this Clematis, are often divided into three groups based on pruning needs, with JOSEPHINE falling into Group 2, meaning it flowers on both old and new wood.

- Black Walnut
Potential Problems
Clematis vines, including Clematis ‘Evijohill’ JOSEPHINE, can occasionally suffer from serious fungal issues, most notably wilt or stem rot, which can be fatal if not addressed promptly. Prevention relies heavily on excellent drainage and avoiding overwatering, as wet feet encourage rot. Fungal diseases like powdery mildew and various leaf spots are common, particularly when air circulation is poor or humidity is high.
To manage pests, regularly inspect the foliage for signs of common culprits like aphids, scale, slugs/snails, and spider mites. Prompt action with appropriate horticultural oils or insecticidal soaps can keep infestations in check. Keeping the root zone cool, shaded, and healthy is the best defense against overall plant stress that invites secondary infestations or diseases.

Conclusion
The Clematis ‘Evijohill’ JOSEPHINE offers unparalleled ornamental value with its large, lush, double flowers appearing consistently throughout the summer months. This reliable Group 2 Clematis is a garden showstopper that marries vigorous growth with spectacular color. Before planting, confirm your location offers the prerequisite support and that root zone conditions remain cool and moist throughout the growing season.
Companion Planting
Selecting appropriate companions is key to successfully managing the root zone temperature for this magnificent Clematis. Plants with shallow or fibrous root systems that prefer consistent moisture work perfectly underneath the vine structure. Consider using low-growing annuals like Impatiens or medium-sized perennials such as Coral Bells (Heuchera), whose foliage will effectively shade the soil surface.
These shorter companions help insulate the roots against summer heat, which is a cultural essential for nearly all climbing Clematis varieties, including JOSEPHINE. Ensure your companion choices also share the preference for well-drained soil and similar moisture regimes to avoid competition for necessary nutrients or excessive drying of the soil profile.
Seasonal Care Calendar
Spring preparation involves a very light pruning, only removing dead wood, as Group 2 specimens rely on last year’s growth for most of their flowers. As the weather warms, apply a thick layer of root mulch (like shredded bark or compost) around the base without touching the main stems. This crucial step maintains the cool, uniformly moist environment Clematis demands.
Summer maintenance focuses primarily on watering, ensuring consistent, deep moisture without waterlogging the soil. If heat stress is observed, ensure the shady buffer around the roots is robust. Deadheading spent flowers lightly may encourage a few sporadic repeat blooms, though it is not strictly necessary for Clematis ‘Evijohill’ JOSEPHINE.
In the fall, after the foliage has died back, resist the urge to heavily cut back the stems; only trim back to just above a pair of healthy buds if necessary, preparing for the Group 2 pruning in early spring. Clean up fallen debris to reduce overwintering sites for potential fungal spores or pests.
