🌹 Large velvet-red flowers, 12–15 cm, from May to September • 🔄 Blooms again after pruning • ☀️ Sun to partial shade • ❄️ Hardy down to –20 °C • 📏 H65 cm | Pot Ø15 cm
Clematis 'Niobe', or large-flowered red clematis, is a deciduous climbing plant of European horticultural origin, selected for the exceptional intensity of its flowers — deep velvet red with purple hues, 12 to 15 cm in diameter, with a highly contrasting center of golden stamens. Its extended flowering period from May to September, blooming again after each light pruning, makes it one of the most generous clematis in the clematis collection.
Compact (2 to 3 m), easy to train and hardy down to –20 °C, it is the ideal choice for bringing an intense, sophisticated color to a trellis or pergola on a balcony or terrace.
Which large-flowered clematis should you choose?
The Verdeia clematis collection offers numerous varieties in distinctive colors. Here's how to place 'Niobe' among the summer-flowering large-flowered clematis in the catalog:
- Clematis 'Niobe' (this plant) — deep velvet-red flowers measuring 12 to 15 cm, flowering May to September, repeat-flowering. The most intense and longest-flowering of the red clematis.
- Clematis 'Hagley Hybrid' — cardinal pink-red flowers, slightly smaller, flowering from June to September. The choice for a softer palette and a very compact habit.
- Clematis 'The President' — large intense violet flowers, repeat-flowering from June to September. The choice for a blue-violet contrast to complement the red 'Niobe' on the same pergola.
- Clematis 'Miss Bateman' — large white flowers streaked with green, flowering in May–June, then repeat-flowering. The choice for a striking white-red contrast paired with 'Niobe'.
Exposure & placement
The Clematis 'Niobe' flowers best in sun or bright partial shade — an overly shady location reduces the intensity of the red and limits flowering. Like all large-flowered clematis, it prefers shaded roots and stems exposed to light. Its moderate height (2 to 3 m) makes it particularly suitable for small supports and pots.
- Exposure: sun or bright partial shade — roots in the shade, stems exposed.
- Support: trellis, mesh, pergola or arch — the petioles wind themselves around any slender support.
- Soil: fertile, cool and well-drained — roots in the shade or mulched.
- In a pot: large container at least 30 cm wide, with the substrate replaced every 2 years.
Mulch the base generously with 10 to 15 cm of organic matter — keeping the roots cool is the main condition for long-lasting, abundant flowering throughout the season.
Watering & care
'Niobe' belongs to pruning group 2 for clematis — it flowers on both the previous year's wood AND the current year's shoots. This characteristic allows repeat blooming: light pruning after the first flush in June triggers a second flowering in August-September. In a pot, the finger test helps you gauge watering. Leaves that turn yellow out of season often have one of the usual causes: soil that is too heavy or a lack of potassium.
- Watering: water regularly during dry periods — keep the substrate moist but not waterlogged.
- Pruning: light pruning after the first flush of flowers in June — cut back by one third to trigger repeat blooming.
- Winter pruning: optional — cut back to 50 cm above the ground in February to renew the framework.
- Fertilizer: potassium-rich fertilizer in spring and after the first flowering to support repeat blooming.
Never cut 'Niobe' back completely in autumn — unlike group 3 clematis, it forms its first buds on the previous year's wood, and hard pruning in autumn would remove the first flush in May.
Decor ideas & plant combinations
The deep velvet red of 'Niobe' creates powerful color contrasts — in a Mediterranean garden or on a flowering jungle terrace, it immediately stands out as the focal point of any composition.
- For a spectacular white-and-red contrast on a pergola, pair it with Clematis armandii on the same support — armandii covers the pergola with fragrant white flowers in February-March, then 'Niobe' takes over with its intense red from May to September, against a backdrop of evergreen foliage all year round.
- For a very intense red and purple pairing, the purple Clematis 'The President' blooms simultaneously from June to September — the two colors complement each other without competing and double the floral density on the same trellis.
- To showcase the velvet red in a pot, a slate-gray or anthracite ceramic container creates the sharpest contrast — the dark background intensifies the brilliance of the red and the purple undertones of the petals.
- For an evergreen backdrop that enhances the flowering, plant it in front of Lonicera henryi — the honeysuckle's glossy, dark green evergreen foliage creates a natural setting that highlights the intensity of the velvet red throughout the season.
At the end of flowering, the clematis's silvery, feathery fruits persist for several weeks — leave them in place to extend the decorative interest until winter pruning.
Verdeia tips
- Prune lightly after the first flowering to trigger repeat flowering: cut the stems back by one third in June as soon as the first flowers fade — this simple intervention triggers a second wave of velvet-red flowers in August-September, extending the season by two months.
- Protect the stems in winter without cutting them back completely: 'Niobe' belongs to group 2 and first flowers on the previous year's wood — in February, optional pruning to 50 cm above the ground renews the framework, but hard pruning removes the first wave of flowers in May.
- Install the support before planting: clematis stems are fragile and difficult to move once they start climbing — secure the trellis or pergola first, then plant and immediately guide the first stems in the right direction.
