Corinne clematis
Clematis ‘Evipo063’
Corinne™ is a compact clematis with white flowers faintly flushed pink near the base. Each flat or nearly flat bloom presents eight gently wavy sepals around white, pink and red-purple stamens. Flowering can continue from May through October, first on older wood and then on fresh shoots. Strong flowering stems also provide cut flowers that can remain fresh indoors for approximately ten days. With a usual height of 90 to 120 cm, this climber suits large containers, patios, obelisks and smaller gardens. Partial shade helps the pale flowers retain their clean appearance while darker neighbouring foliage creates an effective contrast.

Botanical nameClematis ‘Evipo063’
Corinne™ Clematis (Clematis ‘Evipo063’) is a compact climber bred by Raymond Evison and launched at the 2015 Chelsea Flower Show. Its flat or nearly flat flowers face upward or outward and present eight white sepals with a faint pink flush near the base. Gently wavy margins and tapered tips surround refined stamens: filaments are white at the base then flushed pinkish purple, connectives are red-purple and anthers are white. Strong flowering stems also make excellent cut flowers that can remain fresh indoors for approximately ten days. This combination brings a light, clean accent to shaded patios, containers and smaller garden displays.
Corinne generally reaches 90 to 120 cm tall and approximately 50 to 100 cm wide when trained on support. Its low, dense habit belongs to the Boulevard® collection developed for patios and smaller gardens. This clematis prefers partial shade, where dark foliage or deep-coloured flowers emphasize its pale blooms. It suits large containers, obelisks, trellises, airy shrubs and outdoor dining areas. Plant in fertile, moisture-retentive yet well-drained soil, setting the crown 5 to 8 cm below the surface. Keep the root zone cool without covering the crown directly, and install support before planting so fresh leaf stalks can attach as shoots extend.
Flowering can continue from May through October, first on previous-season stems and then on fresh growth. For the breeder’s simple method, cut all stems back to approximately 15 cm above soil level in late winter or early spring. This short pruning renews the compact framework and brings flowers close to eye level. Water deeply when the surface begins to dry, especially in containers, and feed moderately in spring. For bouquets, cut strong stems when flowers have just opened and place them promptly in water. Every clematis is toxic when eaten, and sap can irritate sensitive skin, so wear gloves during pruning and flower cutting.

Growing method
Plant Corinne™ in partial shade in fertile, organic-rich soil that remains moist yet drains well. Dig a hole wider than the root ball and set the crown 5 to 8 cm below the surface to encourage replacement stems. Install an obelisk or trellis before planting and position the crown away from a wall so rainfall reaches the roots. Water deeply after planting, then maintain consistent moisture without saturation. Light mulch or flat stones keep roots cool without covering the base. Guide fresh stems with loose ties. In spring, add compost or balanced fertilizer. Pale flowers show especially well against dark foliage. For bouquets, cut a strong stem when its flower has just opened and place it immediately in a clean vase. Inspect the crown and shoots regularly for slugs, aphids or sudden wilt. Good air circulation helps foliage dry after rain without exposing the plant to severe winds that could damage flowers or stems. During hot periods, check containers more frequently and direct water toward the base rather than the flowers. Remove only damaged material so enough stems remain for the outdoor display. When harvesting a bloom, cut carefully above healthy growth and avoid pulling neighbouring shoots away from their ties or support.

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 Corinne™. 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 Corinne™ 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.
Moisture
Moist soil without standing water
Seasonal care
In late winter or early spring, cut every Corinne™ stem back to approximately 15 cm above soil level, just above strong buds. This simple breeder-recommended method renews the compact framework and encourages flowers near the base. Wear gloves and use clean pruners because sap can irritate skin. Replace worn ties and check support stability. In spring, renew a thin layer of compost and begin regular watering as growth accelerates. Protect fresh shoots from slugs. During flowering, remove only damaged material and cut a few strong stems for bouquets when flowers have just opened. After the first wave, light feeding and steady moisture support fresh blooms into fall. Check containers daily during hot weather. In autumn, collect diseased foliage and inspect drainage. In cold climates, protect pots from wind and repeated freeze-thaw cycles. Keep the crown visible and accessible throughout the year so emerging shoots, moisture and any sudden wilt can be monitored easily. When preparing a bouquet, disinfect pruners before and after cutting. Place stems in water immediately and avoid harvesting every flower from the same side. During rainy periods, space shoots to improve air circulation. After severe heat, water slowly until the entire root ball is moist. Monitor aphids and remove any stem that wilts suddenly. These simple actions maintain balanced growth and regular flowering through October. If container mulch shifts against the crown, move it back gently so new shoots remain visible and air can circulate. Continue tying fresh growth loosely as needed, without tightening older ties around thickening stems.
Container growing
A garden,within reach.
Recommended pot size
At least 50 cm (20 in) deep and wide
Corinne™ is especially well suited to containers because it remains 90 to 120 cm tall. Choose a frost-resistant pot at least 45 to 50 cm deep and wide with several drainage holes. Install a stable obelisk before filling the container. Use rich potting mix that retains moisture without remaining waterlogged and set the crown 5 to 8 cm below the surface. Position the pot in partial shade, where white, faintly pink-flushed flowers remain luminous. Distribute stems with loose ties and keep several strong stems accessible for cutting. Check moisture daily during hot periods and feed moderately in spring. In late winter, cut stems back to approximately 15 cm. In cold climates, raise the pot, protect its sides and shelter it from wind without moving the dormant plant into a heated room. Keep drainage openings clear during winter thaws and leave the crown visible for inspection. Rotate a movable container periodically to balance gentle light and inspect ties after strong winds. For a bouquet, harvest only a few stems at a time and return the pot promptly to its shaded position. Empty standing water from saucers, keep mulch away from the crown and leave enough room around the container for convenient daily moisture checks.

Bloom period
Corinne™ carries flat or nearly flat flowers with eight white sepals faintly flushed pink near the base. Margins are gently wavy and tips tapered. White filaments become flushed pinkish purple, connectives are red-purple and anthers are white. Flowering extends from May through October, first on older wood and then on fresh shoots. Strong stems also provide long-lasting cut flowers suitable for clean, simple indoor arrangements.
Fruiting
Achenes with decorative feathery styles late in the season
Garden associations
In goodcompany.
Companion plants
Pair Corinne™ with purple coral bells, deep-green ferns, blue-green hostas or shrubs carrying bronze foliage. These deeper colours highlight white, faintly pink-flushed blooms in partial shade. Low perennials can keep soil cool, but preserve clear space around the crown for watering and pruning. Avoid overly vigorous plants or aggressive roots that could reduce available moisture. For a soft display, add a few pale-pink flowers without covering the strong stems intended for bouquets or restricting access to the base. Leave enough room to inspect and harvest strong flower stems safely.
Plants to avoid
Avoid highly invasive plants or aggressive roots immediately around the crowns
Frequently asked questions
Your questions,answered.
How should Corinne clematis be pruned?
For Raymond Evison’s simple method, cut every Corinne™ stem back to approximately 15 cm above soil level in late winter or early spring, just above healthy buds. This short pruning renews the compact habit and encourages flowers near the base. Another option is Group 2 pruning: remove dead or weak stems, then shorten the others to vigorous buds so more older wood remains for the earliest flowers. Use clean pruners, wear gloves and collect debris because clematis sap may irritate skin. Inspect the support afterward, replace worn ties and spread fresh shoots loosely before they become intertwined during rapid spring growth.
How can Corinne clematis be used as a cut flower?
Choose a strong stem carrying a flower that has just opened. Cut it early in the morning with clean pruners, just above a healthy bud or side branch, then place it immediately in a bucket of fresh water. Indoors, recut the base slightly on an angle, remove foliage that would sit below the waterline and use a clean vase. Refresh the water regularly and keep the arrangement away from direct sun, heat sources and ripening fruit. Under suitable conditions, a Corinne™ flower can remain fresh for approximately ten days. Wear gloves while cutting because clematis sap may irritate sensitive skin, and collect trimmed material promptly after arranging the bouquet.
Does Corinne clematis suit containers?
Yes. Corinne™ suits a large frost-resistant container at least 45 to 50 cm deep and wide, fitted with several drainage holes and a stable obelisk. Its usual height of 90 to 120 cm in the compact form creates a strong vertical display without becoming imposing on a terrace. Use rich potting mix that retains moisture without remaining waterlogged. Set the crown 5 to 8 cm below the surface, then water until excess drains freely. Check moisture daily during hot weather. 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 Corinne clematis?
Choose partial shade in any aspect that provides gentle, consistent light. Corinne™ was selected for shadier parts of the garden, where white, faintly pink-flushed blooms stand out against darker foliage. Soil should be fertile, organic-rich, moisture-retentive and well drained. Position the crown 30 to 60 cm away from a foundation so rainfall reaches the roots. Light mulch, flat stones or a low companion keeps soil cool without covering the base. Install support before planting and preserve easy access to strong stems if several flowers will be cut for indoor arrangements. Good air circulation helps foliage dry after rain without exposing pale blooms to severe winds.
Is Corinne clematis toxic?
Yes. Like other clematis, Corinne™ 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.

Supporting wildlife
Clematis flowers can be visited by bees and other insects seeking pollen, and some also supply nectar. The specific wildlife value of Corinne™ may vary by region and the availability of other flowers. It is therefore presented as useful to pollinating insects without promising special attraction for butterflies or hummingbirds. Avoid spraying open flowers when pollinators are active.
