Giselle™ Clematis (Clematis ‘Evipo051’) is a compact climber bred by Raymond Evison and introduced commercially in the early 2010s. It stands out for exceptionally abundant flowering. Its single, star-shaped 10 to 12 cm blooms have six softly dusky purple-pink sepals with gently wavy edges, long pointed tips and a paler central bar. Purple-pink filaments surround greyish-white anthers that brighten the centre. Upward- or outward-facing flowers remain clearly visible against deciduous green foliage and create a long vertical display without requiring an imposing garden structure in compact outdoor garden spaces nearby.
Giselle generally reaches 120 to 150 cm tall and spreads approximately 60 to 100 cm. It suits a large container fitted with an obelisk, the base of an arch or pergola, or a position beside a free-standing rose. Partial shade preserves the soft flower colour particularly well; gentle sun is suitable when soil remains cool. Plant in fertile, organic-rich, moisture-retentive yet well-drained soil, setting the crown 5 to 8 cm below the surface. Install support immediately so leaf stalks can grasp it as new stems lengthen steadily through spring outdoors.
Flowering begins in late spring and continues into early autumn, sometimes extending later when growing conditions remain favourable. In late winter or early spring, cut every stem back to approximately 15 cm above soil level to renew growth and encourage flowers near the base. Water deeply whenever the soil surface begins to dry, especially in containers, and feed moderately in spring. Like every clematis, Giselle is toxic when eaten and its sap may irritate sensitive skin; wear gloves during pruning and collect all cut material after every seasonal maintenance session.

Growing method
Pour Clématite Giselle, préparez le sol et le support avant de manipuler le plant de pépinière. Choisissez la mi-ombre avec un sol humide et bien drainé. Installez un support stable, protégez les racines d’une chaleur excessive et manipulez doucement les jeunes tiges. Choisissez une terre travaillable et une période d’établissement permettant un arrosage régulier. Manipulez délicatement les tiges, qui sont fragiles au moment de la plantation. Installez le support avant que les pousses s’entremêlent aux plantes voisines. Pour ces hybrides à grandes fleurs, placez la couronne racinaire environ 5 cm (2 po) sous la surface définitive du sol. Comblez soigneusement, tassez la terre avec l’arrosage et gardez le support à distance de la couronne. Protégez la zone racinaire de la chaleur intense par un paillis léger en laissant la base des tiges accessible. Vérifiez la motte de pépinière ainsi que la terre environnante pendant l’établissement. Évitez une terre compacte qui emprisonne l’eau autour des racines. Au Québec, une plantation printanière en terre travaillable permet de suivre l’enracinement avant l’hiver. Une plantation automnale exige une météo convenable et une période dégelée suffisante pour l’établissement. Ne remplacez pas l’observation du sol et de la météo par une date fixe au calendrier.
Soil and care
Soil & care
Care level
Intermediate
Watering
Water deeply and regularly during establishment so the root ball stays evenly moist without becoming saturated. In hot weather, check containers and plants growing beside walls more often because these sites dry quickly. Direct water toward the base instead of wetting foliage. Established clematis still perform best with consistent moisture and should not be treated as highly drought tolerant, especially while actively extending and flowering.
Soil type
Fertile, organic-rich soil that holds moisture yet drains well suits Giselle™. Loam, clay, sand or chalk-based soil can work when excess water drains effectively. Mature compost improves moisture retention without leaving the crown waterlogged. Avoid sites where winter water collects, and keep the root zone cool during summer. Beside a wall, position the crown far enough from the foundation for rainfall to reach the roots instead of disappearing beneath an overhang.
Fertilization
In spring, add mature compost or apply a balanced fertilizer according to label directions. A second light feeding after the first flush can support Giselle™ repeat bloom. Avoid excessive nitrogen, which encourages foliage at the expense of flowers. Water before and after feeding, then stop fertilizing early enough for stems to mature before winter. In containers, use smaller applications when needed because nutrients leach more quickly with frequent watering.
Seasonal care
In late winter or early spring, cut every Giselle™ stem back to approximately 15 cm above soil level, just above vigorous buds. Wear gloves and use clean pruners because clematis sap may irritate skin. Remove debris, inspect the support and replace worn ties before growth resumes. In spring, add mature compost and renew light mulch without covering the crown. Fan out new shoots while they remain flexible. Water deeply whenever the surface dries, especially in containers. Moderate balanced feeding supports flowering, whereas excessive nitrogen mainly produces foliage. After the first flush, keep soil consistently moist to encourage repeat bloom. Watch for slugs, aphids and sudden wilting. Stop feeding in fall and leave several feathery seed heads for texture. In cold regions, insulate containers and prevent winter water from collecting around the crown. During prolonged rain, inspect drainage and remove diseased leaves that have fallen onto the soil. After windy weather, redirect loose shoots before they break. If growth becomes excessively dense, thin several weak stems instead of shortening the entire plant while buds are forming. Spent flowers may be removed for a tidier appearance, but leave several if feathery seed heads are desired. Check moisture beneath mulch rather than judging only its dry surface. As spring returns, resume watering gradually and protect tender shoots from slugs and severe late frost. Container plants may warm and begin growth earlier than garden plants, so continue monitoring exposed stems during rapid temperature changes. Rotate the pot occasionally for balanced light and confirm that drainage remains open after every extended wet period.

Container growing
Recommended pot size
At least 50 cm (20 in) deep and wide
Giselle™ is especially well suited to containers because it remains 120 to 150 cm tall. Use a frost-resistant pot at least 50 cm deep and wide with several drainage holes. Install a stable obelisk before planting, then fill the container with rich potting mix that holds moisture without remaining waterlogged. Set the crown slightly deeper than it grew in the production pot. Water slowly until excess drains freely, then check moisture daily during hot weather. A thin mulch layer limits evaporation without trapping water against stems. Feed moderately in spring and after the first flush. Before winter, move the pot to a sheltered location, insulate its sides and raise it so drainage remains open. In spring, replace the upper layer of mix and confirm that the support remains stable before new shoots lengthen. Rotate the pot periodically so all shoots receive balanced light. Never leave the container standing in a water-filled saucer, and check that drainage holes remain open after prolonged rain. During summer, water preferably in the morning and direct moisture toward the potting mix rather than foliage. A thin layer of compost in spring renews organic matter without reducing watering space. Loosen ties that begin marking stems, and remove any suddenly wilted shoot promptly with disinfected tools. Shelter large flowers from severe wind, and keep the crown visible so new spring growth can be monitored easily.

Garden associations
Companion plants & uses
Companion plants
Pair Giselle™ with free-standing roses, coral bells, hardy geraniums, catmints or small ornamental grasses that shade the soil lightly without invading the crown. Plum, dark-green or silver foliage emphasizes dusky purple-pink flowers and their paler central bars. White or pale-blue annuals in neighbouring containers extend the palette. Keep clear space around the base for watering, air circulation and pruning. Avoid vigorous plants or aggressive roots that could reduce available moisture or hide emerging clematis shoots in spring. Choose companions with similar light needs.
Garden use
Grow Giselle™ on a sturdy trellis, arch, lower pergola or in a large container fitted with an obelisk. Its usual height of 120 to 150 cm keeps pure dusky purple-pink flowers near eye level while allowing stems to weave through an airy established shrub. Full sun or partial shade keeps the display bright, while The paler central bar remains visible in soft light. A grey wall, dark fence or silver foliage emphasizes the dusky purple-pink flowers and greyish-white anthers. Position the crown away from a dry foundation so rainfall reaches the roots. Keep the base accessible for deep watering, mulch renewal and annual pruning. On a balcony or terrace, anchor support securely and shelter the large blooms from severe gusts. In a border, use low perennials around the root zone without covering the crown. Guide young stems with soft ties and confirm that they do not block a walkway. Deciduous foliage makes support inspection easy in winter. Wear gloves during maintenance and collect cut stems because clematis is toxic when eaten and sap may irritate sensitive skin. Check ties regularly as vigorous stems lengthen during warm weather. Nearby low plants can shade the soil while preserving airflow and access to the crown.
Garden inspiration
Create a romantic display with a large charcoal container, black obelisk and Giselle™ clematis shoots spread in a fan. Add plum coral bells, a small silver artemisia or hardy geraniums below without hiding the crown. Dark foliage brings out the dusky purple-pink sepals and their paler central bars. Beside an arch or pergola, allow stems to mingle with a free-standing rose to stagger the flowering display. In a border, place two matching supports on either side of a bench or entrance for a balanced composition. White annuals in neighbouring pots add crisp contrast without creating permanent root competition. Soft morning or late-day light reveals the gently wavy sepal texture and pale anthers. Renew the composition each spring by directing young shoots toward open sections of the support, then keep the base clear for deep watering and mulch renewal. Subtle nearby lighting can extend enjoyment after sunset without heating the root zone or interfering with climbing stems. The result stays soft and refined.
Frequently asked questions
Frequently asked questions
How should Giselle clematis be pruned?
In late winter or early spring, before active growth resumes, cut every Giselle™ stem back to approximately 15 cm above soil level, just above healthy buds. This short pruning renews the compact habit and stimulates flowering shoots from the base. Use clean pruners, wear gloves and collect debris because clematis sap may irritate skin. Inspect the smaller trellis or obelisk afterward and replace worn ties. When new stems appear, spread them in a fan and tie them loosely before they intertwine. Add light mulch without covering the crown, then resume consistent watering as growth accelerates and flowering shoots begin covering the support.
What colour and form are Giselle clematis flowers?
Giselle™ produces single, star-shaped 10 to 12 cm flowers that face upward or outward. Each bloom generally has six softly dusky purple-pink sepals with elliptical outlines, gently wavy edges and long pointed tips. A paler central bar runs along every sepal, while purple-pink filaments and greyish-white anthers brighten the centre. The colour appears especially harmonious in partial shade or soft light. Fan young stems across the support so numerous flowers remain visible without excessive overlap. Neighbouring plum, silver or dark-green foliage emphasizes the colour and creates an elegant background beside a patio, entrance or frequently used garden path throughout the long flowering season.
Does Giselle clematis suit containers?
Yes. Giselle™ suits a large frost-resistant container at least 50 cm deep and wide, fitted with several drainage holes and a stable obelisk. Its usual height of 120 to 150 cm creates a strong vertical display without becoming too imposing on a terrace. Use rich potting mix that retains moisture without remaining waterlogged. Set the crown slightly deeper than it grew in the production pot, then water until excess drains freely. Check moisture daily during hot weather, especially if the container receives sun. In winter, shelter the pot from wind, insulate its sides and raise it to prevent standing water and repeated freeze-thaw cycles around the roots.
What site suits Giselle clematis?
Choose partial shade where possible because it preserves the soft dusky purple-pink flower colour. Gentle sun is suitable when soil remains cool, but avoid an intensely hot, drying position. Soil should be fertile, organic-rich, moisture-retentive yet well drained. Position the crown 30 to 60 cm away from a foundation so rainfall reaches the roots. Light mulch or a low companion keeps the root zone cool without covering the crown. Install a trellis, arch, pergola or obelisk before planting and preserve easy access to the base for watering, inspection and annual pruning. Good air circulation helps foliage dry after rain while the sheltered site protects broad flowers from strong gusts.
Is Giselle clematis toxic?
Yes. Like other clematis, Giselle™ contains protoanemonin and is toxic to dogs, cats and horses when eaten. Ingestion can cause salivation, vomiting and diarrhea. In people, plant material may cause severe mouth irritation, while sap can irritate sensitive skin. Wear gloves for pruning, wash exposed skin and never present any part as edible. Position the plant away from young children and pets that chew garden plants, and collect cut stems promptly after maintenance. If ingestion occurs or symptoms appear, contact an appropriate medical professional or veterinarian promptly. Do not attempt home treatment unless a qualified professional provides specific instructions for the situation.
