Clematis 'Venosa Violacea'

Clematis 'Venosa Violacea' is a botanical treasure with a long history: it was raised by Lemoine et fils in France in 1883, as a cross of Clematis viticella with an earlier hybrid of C. viticella and C. florida. The result is truly unique – there is no other clematis quite like it. The flowers, 10 to 12 cm across, carry 5 to 6 tepals whose base colour is pure white. Violet-purple veins trace an intricate pattern across each tepal, deepening into a velvety dark-violet margin. Young flowers display the most vivid contrasts; as blooms age, the colouring gently fades to lavender – a shifting colour play that keeps the plant endlessly fascinating. At the centre, a decorative crown of stamens with dark-violet anthers on cream-coloured filaments adds further elegance.

The main flowering period runs from July to September, making 'Venosa Violacea' one of the most reliable late-summer performers in any garden. Its vigorous growth reaches about 250 cm, enough to clothe a trellis, obelisk or pergola impressively. It combines beautifully with pale-coloured or lavender roses – a particularly striking partnership is with the salmon-pink shrub rose 'Bonica'. Thanks to its robust constitution and straightforward care, 'Venosa Violacea' is an excellent choice for both beginners and experienced clematis growers.

'Venosa Violacea' overwinters reliably to Zone 6 (−23.3 to −17.8 °C) and is considered very cold-hardy. In March, cut the plant back hard to about 25 cm – this stimulates the growth of vigorous new shoots and ensures a generous flowering display the following summer. As a classic Pruning Group 3 clematis, maintenance is refreshingly simple. For best results, plant 'Venosa Violacea' in nutrient-rich, consistently moist but well-drained soil in a sunny to partly shaded position.
