Samaritan Jo™ Clematis (Clematis ‘Evipo075’) is a compact climber bred by Raymond Evison for patios, gardens and large containers. Its 10 to 15 cm star-shaped flowers are silvery white with purple edges and a faint pale-green central stripe. Tapering sepal tips create a distinctive outline, while pink-purple stamens with yellow tips add delicate contrast. Many flowers open simultaneously close to the base. Deciduous mid- to dark-green foliage is not variegated and creates a quiet background that emphasizes the nuanced blooms throughout their long flowering season in refined patio displays nearby.
Samaritan Jo generally reaches 120 to 150 cm tall and spreads approximately 50 to 100 cm. It accepts full sun or partial shade, although flowers may fade slightly in intense direct sunlight. Plant it in fertile, moisture-retentive yet well-drained soil, setting the crown 5 to 8 cm below the surface. Install a smaller trellis, obelisk or fine wires immediately so leaf stalks can grasp the support. Light mulch helps keep roots cool without covering the crown. In containers, monitor moisture more frequently during hot weather and shelter large flowers from strong drying wind.
Flowers appear from early summer through mid-fall. In late winter or early spring, the breeder recommends cutting every stem back to approximately 15 cm above soil level. This simple pruning renews the compact framework and encourages flowers close to the base. Light Group 2 pruning is also possible when retaining stems for earlier flowers. Water deeply whenever the soil surface begins to dry. Every clematis is toxic when eaten, and sap can irritate sensitive skin, so wear gloves during pruning, collect cut stems promptly and keep all plant parts away from pets or young children.

Planting & establishment
Planting period
Spring or early fall
Growing method
Plant Samaritan Jo™ in fertile, organic-rich, moisture-retentive yet well-drained soil in gentle light or partial shade. Set the crown 5 to 8 cm below the surface and immediately install a smaller trellis, obelisk or fine wires. Water deeply whenever the surface begins to dry, then add light mulch without covering the crown. Fan out new shoots while they remain flexible and loosen ties as stems thicken. In late winter or early spring, cut every stem back to approximately 15 cm above healthy buds. Add mature compost in spring and feed moderately without excessive nitrogen. Watch for slugs, aphids and sudden wilting. Check container moisture more often, shelter the pot from strong wind and protect it from repeated freeze-thaw cycles. After the first bloom, maintain even moisture to support repeat flowering rather than shortening fresh stems severely. Beside a wall, position the crown away from the foundation so rainfall reaches the roots. After windy weather, redirect loose shoots before they break. Leave several feathery seed heads in fall, then stop feeding so stems can mature before cold weather. Remove fallen diseased leaves, inspect drainage after prolonged rain and never leave a container standing in water. Resume spring watering gradually as buds swell, and protect tender shoots from severe late frost and slug damage.
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 Samaritan Jo™. 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 Samaritan Jo™ 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 Samaritan Jo™ 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
Samaritan Jo™ is especially well suited to containers because it remains approximately 90 to 120 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.

Bloom period
Samaritan Jo™ produces large silvery-white star-shaped flowers 10 to 15 cm across, edged in purple and marked by a faint pale-green central stripe. Pink-purple stamens with yellow tips and tapering sepal ends add contrast. Many flowers open simultaneously close to the base from early summer through mid-fall. Short pruning in late winter, gentle light and consistently moist soil encourage this long sequence and limit fading under intense direct sunlight.
Garden associations
Companion plants & uses
Companion plants
Pair Samaritan Jo™ with low perennials that shade the soil lightly without invading the crown, such as coral bells, hardy geraniums, catmints or small ornamental grasses. Burgundy foliage repeats the purple edges, while dark-green leaves emphasize silvery white. White or pale-pink 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 Samaritan Jo™ on a smaller obelisk, patio trellis or in a large container beside a bright outdoor dining area. Its 120 to 150 cm height keeps silvery-white flowers, purple edges and coloured stamens easy to appreciate without looking overhead. An east-, west- or bright north-facing position often provides enough light while limiting fading from midday sun. A charcoal-grey or dark-green background highlights the pale blooms. Position the crown away from a dry foundation so rainfall reaches the roots, and preserve open space for watering and pruning. On a balcony, anchor the support securely and shelter the container from strong gusts. In a border, place the plant near the front or allow it to weave through a small airy shrub that does not compete heavily for moisture. Check regularly that stems do not block a walkway, and redirect them with soft ties. Deciduous foliage makes winter support inspection easy. Wear gloves during maintenance and collect cut stems because clematis is toxic when eaten and sap may irritate skin. Nearby low perennials can shade the soil gently, provided they leave the crown visible and do not compete strongly for available moisture.
Garden inspiration
Create a refined focal point with a large charcoal container and black obelisk. Fan out Samaritan Jo™ shoots so silvery-white flowers cover the support evenly. Add burgundy coral bells and several dark-green foliage plants below without hiding the crown, repeating the purple edges while emphasizing the faint pale-green stripe. A grey wall highlights pink-purple stamens with yellow tips. In a border, place two matching supports on either side of a bench for a symmetrical composition. Compact scale keeps flowers near eye level and makes photography easy. Renew the display every spring after pruning by directing fresh shoots toward open sections. Keep the base clear enough to see buds, water deeply and remove any suddenly wilted stem promptly. White annuals in neighbouring pots add crisp contrast without creating permanent root competition. Soft evening light reveals the flower edges and tapering tips particularly well. A small solar light placed nearby can extend enjoyment after sunset without interfering with the stems or warming the root zone.
Frequently asked questions
Frequently asked questions
How should Samaritan Jo clematis be pruned?
In late winter or early spring, before active growth resumes, cut every Samaritan Jo™ 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 flower colour and foliage does the clematis Samaritan Jo have?
Samaritan Jo™ produces large silvery-white star-shaped flowers 10 to 15 cm across. Each sepal has a purple edge, faint pale-green central stripe and tapering tip. Pink-purple stamens end in yellow and create delicate contrast at the centre. Flowers may fade slightly under intense direct sun, so bright partial shade helps preserve their details. To appreciate them, train stems over a smaller support that keeps blooms close to eye level. Mid- to dark-green leaves without variegation naturally highlight the pale flowers. A charcoal or dark-green background makes the coloured edges and central details especially clear throughout the long flowering period. outdoors.
Does Samaritan Jo clematis suit containers?
Yes. Samaritan Jo™ is especially suitable for containers because it remains approximately 90 to 120 cm tall. Choose a frost-resistant pot at least 50 cm deep and wide with several drainage holes and a stable obelisk. 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. In winter, shelter the container from wind, insulate its sides and raise it to prevent standing water and repeated freeze-thaw cycles around the roots. Confirm that drainage remains open before vigorous spring growth resumes.
What site suits Samaritan Jo clematis?
Choose a bright site protected from scorching midday sun. Samaritan Jo™ especially prefers partial shade and suits an east-, west- or bright north-facing position. Soil should be fertile, moisture-retentive yet well drained. Position the crown 30 to 60 cm away from a foundation or wall so rainfall can reach the roots. Light mulch, flat stones or a low companion plant protect the root zone without covering the crown. Install support before planting and preserve easy access to the base for watering and annual pruning. Good air circulation also helps foliage dry after rain and reduces prolonged dampness around crowded stems. Shelter flowers from strong wind.
Is Samaritan Jo clematis toxic?
Yes. Like other clematis, Samaritan Jo™ 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.
