Jackmanii and Pink Champagne Clematis Duo (Clematis ‘Jackmanii’ and Clematis ‘Kakio’) combines two deciduous climbers with complementary colours. ‘Jackmanii’ carries velvety violet-purple flowers about 10 cm across, while Pink Champagne opens large purplish-pink blooms with paler central bars and yellow stamens, commonly 12 to 16 cm wide. Leaf stalks curl around a suitable support and vines can reach approximately 2.5 to 4 m. The pairing supplies an early pink display, followed by abundant deep-purple summer colour and a later repeat from Pink Champagne, creating a layered effect over a long portion of the gardening season.
Both clematis prefer full sun or partial shade in fertile, moisture-retentive yet well-drained soil. Their roots benefit from a cool zone protected by light mulch, flat stones or a low companion plant, while the crown remains free of smothering material. Install fine trelliswork, wires or fencing at planting time so the leaf stalks can grasp it. Deep, regular watering supports establishment and remains especially important in containers. Set the crown 5 to 8 cm below soil level to encourage shoots from below ground, and allow roughly 1 to 1.5 m of practical width for the combined planting.
The key maintenance point is keeping the two pruning methods separate. Pink Champagne is a Group 2 clematis: remove dead tips in spring and trim lightly after its first flush. ‘Jackmanii’ belongs to Group 3 and flowers on current-season growth, so cut its stems back to about 30 to 45 cm in late winter. A small coloured label beside each crown makes identification easier. This duo suits trellises, pergolas, fences and large supported containers. Every clematis is toxic when eaten, and sap may irritate sensitive skin, so the plants are ornamental only and should be handled with garden gloves.

Planting period
Spring or early fall
Growing method
Plant both clematis in fertile, moisture-retentive yet well-drained soil in full sun or partial shade. Set each crown 5 to 8 cm below soil level and immediately provide fine stems, wires or trelliswork that the leaf stalks can wrap around. Water deeply after planting, then maintain even moisture without waterlogging the root zone. Keep roots cool with light mulch, flat stones or a low companion plant. Mark each crown clearly: Pink Champagne receives light Group 2 pruning to preserve early flowers, whereas ‘Jackmanii’ is cut back to 30 to 45 cm in late winter as a Group 3 clematis. During the first season, inspect ties weekly and loosen any that mark the stems. Fan shoots across the support to improve light and air circulation. Add compost in spring, followed by light feeding after the first flush. Watch for slugs, aphids and symptoms of clematis wilt. In fall, allow foliage to yellow naturally before removing only dry or diseased material. Light protection around the roots helps a young duo through its first winter, but each crown must remain able to breathe. Resume training early in spring before new stems become tangled and harder to separate.

Fertilization
In spring, add mature compost or apply a balanced fertilizer according to label directions. A second light feeding after Pink Champagne’s first flush can support repeat bloom. Avoid excessive nitrogen, which encourages foliage at the expense of flowers. Water before and after feeding, and stop fertilizing early enough for stems to mature before winter. Container plants may need smaller, more regular applications because nutrients leach with watering.
Seasonal care
In early spring, remove winter protection gradually and inspect both crowns. Keep a separate label for each cultivar. Pink Champagne belongs to Group 2: cut only dead tips back to healthy buds, then shorten selected stems lightly after the first flush. ‘Jackmanii’ belongs to Group 3: before growth begins, cut all of its stems back to about 30 to 45 cm, just above vigorous buds. Train new shoots over the support without tying them tightly. Maintain even soil moisture, feed moderately and remove damaged growth. In fall, leave the fluffy seed heads for ornamental interest, then apply protective mulch around rather than directly over each crown. Check ties and supports before winter storms so old material does not rub or constrict the stems. During active growth, fan stems over the support, replace tight ties and water deeply whenever the upper soil begins to dry. A layer of mature compost supports flowering without forcing excessive leafy growth. After Pink Champagne’s first flush, light trimming and moderate feeding can encourage repeat bloom. Watch for slugs on young shoots, aphids and any sudden wilting. Cut an affected stem back to healthy tissue with a disinfected tool and do not leave diseased debris below the vines. Confirm that the support remains stable under wet foliage and that stems do not block nearby openings. Continue checking container moisture through warm autumn weather, even after flowering slows, so roots enter winter without drought stress.
Container growing
Container growing
Choose a container at least 45 cm deep and wide with several drainage holes. Use a rich, structured potting mix, then secure a trellis firmly to the container or a wall. Set each crown 5 to 8 cm below the surface and keep the mix consistently moist. Containers heat and dry faster than garden soil, so pale mulch and frequent moisture checks help protect the roots. In cold regions, shelter the pot from wind, insulate its sides and reduce repeated freeze-thaw cycles. Mark both crowns permanently and prune each cultivar according to its own group rather than cutting the entire duo in the same way. Water until excess moisture drains freely, then empty the saucer. Rotate the container periodically when light comes mainly from one direction, and spread shoots over the entire structure. Use diluted feeding rather than one heavy dose. Replace the top layer of mix with fresh compost in spring. Check ties, drainage holes and trellis stability after strong winds. If roots completely fill the pot, move the duo into a larger container in spring, handling crowns and stems gently. Never allow a decorative outer pot to trap water around the root ball after rain.

Bloom period
Pink Champagne opens large purplish-pink flowers with paler central bars in early summer and can bloom again in late summer or early fall. ‘Jackmanii’ produces abundant velvety violet-purple flowers on current-season shoots from early through late summer. Together, the two cultivars create a colourful sequence from June into September, depending on local climate, establishment, moisture and pruning. Consistent moisture and cultivar-specific pruning support that sequence and protect the early flush.
Garden associations
Companion plants & uses
Companion plants
Pair these clematis with low perennials that keep roots cool without forming an invasive mat, such as hardy geraniums, coral bells, catmints or smaller ornamental grasses. Silver foliage and white or pale blue flowers highlight both Jackmanii’s violet tones and Pink Champagne’s pink colouring. A sturdy climbing rose can share the structure when space, light and air circulation remain adequate for every plant. Keep a clear area around each crown, however, so watering, permanent labels and separate pruning remain easy.
Garden use
Plant the duo at the base of a trellis, fence or pergola capable of supporting several metres of growth. Leaf stalks grasp relatively fine wires and slats more readily than thick, smooth beams. Guide ‘Jackmanii’ shoots toward one side and Pink Champagne toward the other in early spring, then allow them to mingle near the centre. Low perennials can shade the roots without competing heavily with the crowns. In a large container, anchor the support securely before filling the pot. Avoid narrow passages where irritating sap could contact skin repeatedly, and keep the planting away from pets that tend to chew garden plants. For broad coverage, add horizontal wires at regular intervals and guide shoots into open areas before they tangle. An east- or west-facing position often balances light with root-zone coolness. Beside a wall, plant slightly away from the foundation so rainfall can reach the roots more effectively. The duo can frame an entrance or form a seasonal screen, but preserve easy access to both crowns for pruning. Wear gloves while training stems and collect clippings promptly because sap is irritating and every part is toxic if eaten. Keep the support clear of gutters, siding vents and movable gates as growth expands.
Garden inspiration
Create a living panel by guiding ‘Jackmanii’ over the left half of a trellis and Pink Champagne over the right. Cross several shoots through the centre to form a natural transition from deep violet to luminous pink. Repeat those colours below with violet-blue hardy geraniums, silver-leaved coral bells and a few white flowers. A discreet label at each crown makes the different Group 2 and Group 3 pruning routines easy to remember. In a large container, choose a stable structure that can remain in place all year and add pale mulch to keep the roots cooler during hot weather. For a softer mood, let Pink Champagne dominate near a seating area and guide ‘Jackmanii’ toward the background. For a more graphic contrast, alternate stems along horizontal wires. Subtle lighting placed in front of the trellis highlights paler flowers at dusk without heating the root zone. Leave feathery seed heads for several weeks after bloom to add silvery texture, then remove them if a cleaner structure is preferred. Repeat one flower colour in nearby containers to connect the vertical display with the surrounding patio or border.
Frequently asked questions
Frequently asked questions
How should both clematis be pruned without losing flowers?
Mark each crown permanently because the two cultivars require different pruning. Pink Champagne belongs to Group 2 and produces its first flowers on growth retained from the previous year. In spring, remove only dead tips back to healthy buds, then shorten selected stems lightly after the first flush. ‘Jackmanii’ belongs to Group 3 and flowers on new growth, so cut all of its stems back to about 30 to 45 cm in late winter. Guide the fresh shoots separately at first, then let them intermingle over the support. Clear labels prevent accidental hard pruning of Pink Champagne and loss of its early display. Make every cut with clean tools and wear gloves because sap may irritate skin.
What support works best for this clematis duo?
Clematis climb with curling leaf stalks rather than tendrils or adhesive roots, so they grasp wires, slender rods and relatively narrow slats most effectively. A sturdy trellis, wire-equipped fence, arch or pergola with a fine framework works well. Install the support before or during planting to avoid disturbing roots later. Because both vines can reach several metres, anchor the structure securely and inspect it each spring. Tie young shoots loosely with soft material until their leaf stalks take over. Avoid thick, smooth posts as the only climbing surface because the vines cannot wrap around them without added wire or mesh. Preserve access to both crowns for separate annual pruning and routine inspection.
Can the duo grow in a large container?
Yes, provided the container is at least 45 cm deep and wide, has several drainage holes and carries a very stable support. A larger pot makes room for two crowns and reduces rapid moisture swings. Use a rich, structured potting mix, keep it consistently moist and check watering daily during hot periods. Container roots are more exposed to cold than garden-grown roots, so shelter the pot from wind and insulate its sides in colder regions. Keep a permanent label beside each cultivar so the Group 2 and Group 3 pruning methods remain clear. Avoid leaving the pot in standing winter water. A light surface mulch also helps limit overheating and rapid evaporation during summer.
Why keep the roots cool while the vines reach the sun?
The stems and flowers benefit from good light, while a cooler root zone helps the soil maintain even moisture. This combination reduces stress during hot weather and supports continuous growth. Spread light organic mulch around the base without covering the crown, place several flat stones nearby or use a low, noncompetitive perennial for shade. These methods do not replace watering, so always check moisture below the mulch. Do not let a dense shrub completely shade the climbing stems or restrict air circulation, because clematis foliage should dry after rain. Cool roots and well-lit vines work together rather than representing two separate planting conditions.
Are Jackmanii and Pink Champagne clematis toxic?
Yes. Clematis 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 duo away from young children and pets that chew 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. Keep cut stems out of any compost area accessible to pets or grazing animals.
