🌸 Long, fragrant, trailing purple clusters • 🌿 Vigorous climber • ☀️ Full sun to partial shade • ❄️ Hardy down to −15 °C • 📏 H65 cm | Pot Ø15 cm
Wisteria sinensis 'Caroline' is a purple wisteria native to China, famous for its long clusters of delicately scented mauve flowers that cascade from spring onwards. It transforms walls, pergolas, and balconies into truly poetic scenes.
Hardy down to −15 °C and very vigorous, it improves year after year — the older it gets, the more abundant and spectacular its blooms become.
Which wisteria variety should you choose?
The Wisteria genus includes two main species with different characteristics. Here's how Wisteria sinensis 'Caroline' stands out from other varieties in the catalog:
- Wisteria sinensis 'Caroline' (this plant) — very fragrant purple clusters, early flowering before leaves, very vigorous. The classic purple version with the strongest scent.
- Wisteria sinensis 'Prolific' — abundant blue-violet clusters, early and repeat flowering, very floriferous. The most floriferous blue version.
- Wisteria floribunda 'Alba' — very long, delicately scented white clusters, slightly later flowering. The classic pure white version.
- Wisteria floribunda 'Rosea' — very fragrant pale pink clusters, elegant habit. The romantic pink version.
- Wisteria floribunda 'Naga Noda' — exceptionally long double purple clusters, very spectacular. The most sumptuous purple version.
Light & location
'Caroline' wisteria loves light and warmth — full sun or bright partial shade, ideally facing south or west for maximum flowering. Like all wisterias, its roots need space and depth. Provide a very sturdy support from planting: a mature wisteria can weigh several dozen kilos.
- Exposure: full sun to partial shade — ideally south or west facing.
- Support: pergola, wall, arch, balcony — must be solid and well anchored.
- Soil: ordinary, deep, and well-drained — avoid soils too rich in nitrogen.
- In a pot: large container at least 30 cm in diameter and depth.
Wisteria sinensis flowers before leafing out — its clusters appear on bare wood in early spring, which visually sets it apart from Wisteria floribunda, which flowers at the same time as the leaves appear.
Watering & care
'Caroline' wisteria is undemanding once established. Water regularly for the first two years to encourage rooting, then gradually water less often. Pruning is the essential care — twice a year to stimulate flowering and control vigor. Stems pruned in summer make easy cuttings. If leaves turn yellow out of season, check drainage and nutrient supply.
- Watering: regular for the first two years, moderate afterwards.
- Summer pruning: July-August — shorten new shoots to 5–6 leaves.
- Winter pruning: January-February — shorten the same shoots to 2–3 buds.
- Fertilizer: never nitrogen — it promotes leaves at the expense of flowers.
If your wisteria doesn't flower, check two things: too much nitrogen in the soil and not enough sun — these are almost always the reasons a wisteria produces leaves but no flowers.
Decor ideas & plant combinations
The fragrant purple clusters of Wisteria 'Caroline' create a Mediterranean and romantic atmosphere. Its early flowering on bare wood — before the leaves — offers a unique floral display from early spring.
- For a two-tone wisteria duo, the white Wisteria floribunda 'Alba' complements the purple Caroline on the same support — the two colors contrast elegantly and their flowering is slightly staggered for a longer season.
- To frame the wisteria with a complementary scent, the 'Halliana' honeysuckle extends the fragrant season from June to September — when the wisteria rests after its great spring flowering.
- For a pink and purple balcony trellis, the Crazy in Love Pink climbing rose plays off the wisteria's purple for a very romantic two-tone floral composition on the same railing.
- To cover the base of a wall in evergreen white, the Trachelospermum 'Star of Venice' with its evergreen foliage complements the wisteria, which loses its leaves in winter — a duo that keeps the support covered all year round.
Verdeia tips
- Install the support before planting: a mature wisteria is a heavy, powerful plant capable of bending or tearing down light structures — pergolas, arches or trellises must be firmly anchored from the start, before planting.
- Strictly follow the twice-yearly pruning schedule: prune in July-August to 5–6 leaves, then in January-February to 2–3 buds — this twice-yearly rhythm is what triggers abundant spring flowering, not light alone.
- Guide the main stems from the first year: direct and tie the main stems in the desired direction from planting — once woody, they twist irreversibly and become impossible to redirect without breaking.

What should I do when my plant arrives?
Open your package as soon as you receive it and carefully remove the plant from its packaging. Let it acclimate for 24 hours in its new environment before watering. If it has been slightly stressed during transport, it will recover its shape after one or two days in the light.
What should I do if my plant arrives damaged?
Contact us within 48 hours with a photo of the issue. Our team will assess the situation and offer you the best solution: replacement, partial refund, or recovery advice.
