The Best Climbing Flowers for Your Garden: A Complete Guide

Why Grow Climbing Flowers?

Climbing flowers are among the most versatile and impactful plants in the gardener’s toolkit. Where borders and beds work horizontally, climbers work vertically — transforming bare walls, fences, pergolas, arches, and trellises into living tapestries of colour and fragrance. In a small garden they multiply the available growing space without taking up precious ground area. In a larger plot they add height, drama, and structure that ground-level planting simply cannot achieve.

Beyond their aesthetic value, flowering climbers provide important habitat for wildlife: nesting sites for birds, shelter for insects, and nectar sources for bees and butterflies. Many of the most beautiful climbing plants are also among the most wildlife-friendly.

This guide covers the finest climbing flowers available to gardeners, with detailed advice on varieties, growing conditions, support requirements, and care.

1. Clematis (Clematis spp.)

Best for: Walls, fences, pergolas, growing through other shrubs and trees Height: 1.5–10 m depending on variety Flowering season: January–November depending on variety Hardiness: Most varieties fully hardy

Clematis is the most diverse and widely grown of all flowering climbers, with species and hybrids spanning virtually every season, colour, and size. From the nodding, wine-purple bells of Clematis viticella to the enormous flat-faced blooms of large-flowered hybrids like ‘Nelly Moser’, there is a clematis for almost every garden situation. With careful variety selection, it is possible to have clematis in flower for ten or more months of the year.

Clematis climb by twisting their leaf stalks (petioles) around supports, so they require thin trellis, wire, or the stems of host plants to cling to.

Top varieties:

  • Clematis ‘Nelly Moser’ — One of the most iconic large-flowered clematis; pale mauve-pink petals with a deep carmine central bar. Best in partial shade to prevent fading.
  • Clematis montana ‘Rubens’ — A vigorous early-flowering species that smothers itself in pale pink, vanilla-scented flowers in May. Can reach 8–10 m.
  • Clematis viticella ‘Purpurea Plena Elegans’ — Double, rosette-like flowers in deep rosy-purple throughout summer; extremely robust and disease-resistant.
  • Clematis armandii — An evergreen species with glossy, leathery leaves and intensely fragrant white flowers in March and April; needs a sheltered south- or west-facing wall.
  • Clematis tangutica — Produces charming nodding yellow lantern flowers from July to October, followed by silky decorative seed heads that persist through winter.
  • Clematis cirrhosa ‘Freckles’ — Winter-flowering species with cream and crimson-speckled nodding bells from November to February.

Growing tips: Clematis thrive with their roots in cool, moist shade and their top growth in sun or partial shade. Plant deeply — burying the stem 10–15 cm below soil level protects against clematis wilt. Pruning depends on the group: Group 1 (early-flowering species) needs little pruning; Group 2 (large-flowered, early summer) should be lightly tidied in late winter; Group 3 (late-flowering) should be cut back hard to 30–45 cm in late winter.

2. Wisteria (Wisteria sinensis / W. floribunda)

Best for: House walls, large pergolas, substantial structures, specimen plants Height: 10–30 m at maturity; easily managed at 5–8 m Flowering season: May–June, often with a second flush in August Hardiness: Fully hardy

Wisteria is perhaps the most romantically beautiful of all flowering climbers. The long, pendulous racemes of lilac, violet, white, or pink flowers appear in late spring before the leaves fully emerge, draping walls and pergolas in spectacular curtains of blossom. The scent — sweet, fresh, and slightly honey-like — carries far on warm May air. A mature wisteria in full flower is one of the great sights of the garden year.

Wisteria is a vigorous, long-lived plant that requires a solid support structure as established plants can become very heavy. It climbs by twining its stems around supports.

Top varieties:

  • Wisteria sinensis ‘Prolific’ — Chinese wisteria with fragrant lilac-blue racemes up to 30 cm long; vigorous and reliably free-flowering.
  • Wisteria floribunda ‘Multijuga’ — Japanese wisteria producing extraordinarily long racemes — up to 90 cm — of fragrant violet flowers.
  • Wisteria sinensis ‘Alba’ — Pure white flowers with a particularly sweet fragrance; elegant and refined.
  • Wisteria floribunda ‘Rosea’ — Soft pink and purple flower racemes; a more unusual and delicate-looking alternative to the common lilac forms.

Growing tips: Plant in full sun in deep, fertile, well-drained soil. Wisteria requires twice-yearly pruning to flower well and remain manageable: in summer (July–August), cut back all new side shoots to 5–6 leaves from the main framework; in winter (January–February), cut the same shoots back to 2–3 buds. Newly planted wisterias may take 3–7 years to flower freely — purchasing a grafted plant is the most reliable route to earlier blooms.

3. Climbing Rose (Rosa — climbing and rambling varieties)

Best for: Walls, fences, pergolas, arches, obelisks, growing into trees Height: 2–12 m depending on type and variety Flowering season: June onwards (climbers repeat-flower; ramblers typically flower once) Hardiness: Most varieties fully hardy

Climbing and rambling roses represent the most romantic use of a flowering climber. Climbing roses (which repeat-flower) and rambling roses (which flower once in summer with extraordinary profusion) can be trained over virtually any garden structure, transforming it into a cascade of fragrant blooms. Roses need to be tied in to their supports as they do not self-cling, but this also means they can be precisely directed to fill any space.

Top varieties:

  • Rosa ‘Madame Alfred Carrière’ — A classic Noisette climbing rose with pale blush-pink to white double blooms and excellent fragrance. Repeat-flowering and tolerant of a north-facing wall — almost uniquely versatile.
  • Rosa ‘New Dawn’ — One of the most popular climbing roses ever bred; soft pearl-pink flowers with a fresh fragrance and reliable repeat-flowering.
  • Rosa ‘Generous Gardener’ — David Austin climbing rose with large, cupped, soft pink flowers and a strong myrrh fragrance; superb on a pergola or arch.
  • Rosa ‘Veilchenblau’ — A rambler with clusters of unusual blue-violet flowers fading to grey-lavender; virtually thornless and tolerant of partial shade.
  • Rosa ‘Seagull’ — Vigorous rambler for growing into large trees; masses of small, fragrant single white flowers with golden stamens in June.
  • Rosa ‘Zéphirine Drouhin’ — An old Bourbon climber with deep pink, intensely fragrant flowers; notably thornless, making it ideal for arches and walkways.

Growing tips: Plant in full sun (partial shade for ‘Madame Alfred Carrière’ and ‘Veilchenblau’) in rich, fertile, well-drained soil. Tie in new shoots in autumn or winter, fanning them out as horizontally as possible — this encourages more lateral flowering shoots and better coverage. Prune repeat-flowering climbers in late winter; prune ramblers after flowering by removing flowered stems to the base.

4. Honeysuckle (Lonicera spp.)

Best for: Pergolas, arches, fences, wildlife gardens, fragrant gardens Height: 3–7 m depending on variety Flowering season: June–September Hardiness: Most varieties fully hardy

Honeysuckle is one of the most evocative of all garden climbers, its tubular flowers producing one of the sweetest and most recognisable fragrances in the plant world — particularly intense in the evening when it attracts hawkmoths. The flowers are a valuable source of nectar for long-tongued bees and butterflies, and the berries that follow provide food for birds. Honeysuckle climbs by twining its stems around supports.

Top varieties:

  • Lonicera periclymenum ‘Serotina’ — The late Dutch honeysuckle; rich purple-red and cream flowers from July to October; one of the most fragrant and reliable garden honeysuckles.
  • Lonicera periclymenum ‘Graham Thomas’ — Large, pure yellow flowers with exceptional fragrance over a long summer season.
  • Lonicera x tellmanniana — Spectacular large, deep copper-orange flowers in June; no fragrance but superb visual impact and one of the best honeysuckles for partial shade.
  • Lonicera japonica ‘Halliana’ — Semi-evergreen with small, intensely fragrant white flowers ageing to yellow; very vigorous and useful for rapid coverage.

Growing tips: Plant in moist, humus-rich, well-drained soil with the roots in shade and the top growth in sun or partial shade. Honeysuckles can become tangled and congested over time; cut back hard every 2–3 years in late winter to rejuvenate them.

5. Jasmine (Jasminum officinale and relatives)

Best for: Sheltered walls, pergolas, fragrant gardens Height: 3–10 m Flowering season: June–September (summer jasmine); November–March (winter jasmine) Hardiness: Summer jasmine hardy to around -10°C; winter jasmine fully hardy

Two distinct plants carry the jasmine name in British gardens, and both deserve a place. Common jasmine (Jasminum officinale) is a vigorous twining climber producing masses of small, pure white flowers with an intoxicating, intensely sweet fragrance through summer. Winter jasmine (Jasminum nudiflorum) is not fragrant, but earns its place by producing cheerful bright yellow flowers on bare green stems through the depths of winter.

Top varieties:

  • Jasminum officinale ‘Argenteovariegatum’ — White-variegated foliage with the classic fragrant white flowers; more ornamental than the plain-leaved species.
  • Jasminum officinale ‘Clotted Cream’ — An unusual form with creamy-yellow flowers; subtle and elegant.
  • Jasminum nudiflorum — Winter jasmine; bright yellow flowers on arching green stems from November to February; invaluable for winter colour. Best tied against a wall rather than left to scramble freely.
  • Jasminum x stephanense — A hybrid with pale pink fragrant flowers in June; slightly less vigorous than common jasmine.

Growing tips: Summer jasmine requires a warm, sheltered position in full sun and well-drained soil. It climbs by twining and needs wire or trellis support. Prune after flowering, removing older stems to encourage fresh growth. Winter jasmine tolerates a north-facing wall and needs tying in as it does not self-support.

6. Passion Flower (Passiflora caerulea)

Best for: Sunny sheltered walls, exotic-looking planting schemes, wildlife gardens Height: 4–10 m Flowering season: June–September Hardiness: Hardy to around -10°C in sheltered positions

The passion flower produces arguably the most exotic and structurally fascinating flower of any hardy garden climber. The intricate blooms — white petals surrounding a corona of blue, purple, and white filaments, with prominent stamens and pistil at the centre — look almost architectural in their complexity. In warm summers, the flowers are followed by orange egg-shaped fruits. The plant climbs rapidly using tendrils and provides dense, fast coverage.

Top varieties:

  • Passiflora caerulea — The standard hardy passion flower; white and blue-purple flowers throughout summer; the most reliable for temperate gardens.
  • Passiflora caerulea ‘Constance Elliott’ — A pure white-flowered form with a more refined, elegant appearance; equally hardy.

Growing tips: Plant against a south- or west-facing wall in full sun in well-drained soil. Passiflora caerulea is vigorous and can spread via underground runners — be prepared to control its spread. Mulch the base in autumn to protect the roots in cold winters.

7. Solanum / Potato Vine (Solanum laxum)

Best for: Sunny walls, fast coverage, long flowering season Height: 5–8 m Flowering season: June–October Hardiness: Hardy in mild areas; may be cut back in hard winters but usually regenerates

Solanum laxum is an elegant and underused flowering climber that produces loose clusters of star-shaped flowers with prominent yellow anthers over an exceptionally long season. The white form ‘Album’ is particularly refined and pairs beautifully with roses and clematis on a warm wall. It is not fully evergreen in cold winters but regenerates quickly from the base in spring.

Top varieties:

  • Solanum laxum ‘Album’ — Pure white star-shaped flowers with yellow anthers; clean, elegant, and remarkably free-flowering from June to October.
  • Solanum crispum ‘Glasnevin’ — A related species with blue-purple flowers and yellow anthers; slightly hardier and more vigorous; one of the most popular climbing wall shrubs.

Growing tips: Plant in full sun in well-drained soil against a sheltered south- or west-facing wall. Tie in new growth regularly as it grows quickly. Cut back frost-damaged stems in spring.

8. Star Jasmine (Trachelospermum jasminoides)

Best for: Warm sheltered walls, evergreen coverage, fragrant gardens Height: 3–8 m Flowering season: June–August Hardiness: Hardy to around -10°C in sheltered positions

Star jasmine is one of the finest evergreen climbing plants for a sheltered garden. The small, pinwheel-shaped white flowers are produced in great abundance in midsummer and carry a rich, sweet fragrance that rivals true jasmine. The glossy, dark evergreen foliage — which often takes on attractive burgundy and bronze tints in winter — provides year-round interest and dense, attractive coverage.

Top varieties:

  • Trachelospermum jasminoides — The standard star jasmine; the most widely available and reliable form for temperate gardens.
  • Trachelospermum jasminoides ‘Variegatum’ — A variegated form with cream and green leaves; slightly less vigorous but highly ornamental.
  • Trachelospermum asiaticum — A related species with smaller cream flowers; slightly hardier and more compact.

Growing tips: Plant in a sheltered south- or west-facing position in full sun to partial shade in well-drained soil. Star jasmine is a slow starter but accelerates strongly once established. It climbs by twining and needs wire or trellis support. Little pruning is required beyond removing dead wood and trimming to shape after flowering.

9. Chilean Glory Flower (Eccremocarpus scaber)

Best for: Fast summer coverage, containers, annual or short-lived perennial use Height: 3–5 m in a season Flowering season: June–October Hardiness: Half-hardy; treated as an annual in most temperate gardens

Eccremocarpus scaber is a fast-growing, delicate climber that produces a dazzling display of small tubular flowers in vivid shades of orange, red, yellow, and pink from midsummer onwards. In mild gardens it may overwinter, but in most areas it is grown as an annual from seed sown under glass in late winter. Its speed of growth makes it invaluable for rapid colour on an arch or obelisk while slower-growing permanent climbers establish.

Top varieties:

  • Eccremocarpus scaber — The species, typically orange-red; vivid and long-flowering.
  • Eccremocarpus scaber ‘Aureus’ — Yellow-flowered form; softer and more elegant.
  • Eccremocarpus scaber ‘Tresco Scarlet’ — Deep scarlet flowers; one of the richest-coloured selections.

Growing tips: Sow seed under glass in February–March and plant out after the last frost in a warm, sunny, sheltered position. Eccremocarpus climbs by tendrils and appreciates thin wire or trellis support. Water regularly and feed with a liquid fertiliser through summer for the best display.

10. Trumpet Vine (Campsis radicans / C. x tagliabuana)

Best for: Hot sunny walls, exotic-looking gardens, late-summer colour Height: 6–12 m Flowering season: July–September Hardiness: Hardy to around -15°C once established; young plants need protection

Campsis is a spectacular trumpet-flowered climber for the sunniest, most sheltered wall in the garden. The large, flared, trumpet-shaped flowers in vivid shades of orange, red, and scarlet are produced in bold terminal clusters throughout late summer and are particularly attractive to bees. Campsis clings to walls by means of aerial rootlets, similar to ivy, making it one of the few truly self-supporting flowering climbers.

Top varieties:

  • Campsis radicans ‘Flava’ — Soft yellow trumpet flowers; a cooler, more refined alternative to the typical orange and red forms.
  • Campsis x tagliabuana ‘Madame Galen’ — The most widely grown campsis; large, deep salmon-orange trumpets; vigorous and reliably floriferous.
  • Campsis radicans ‘Crimson Trumpet’ — Rich deep red flowers; bold and dramatic.

Growing tips: Plant in full sun in well-drained fertile soil against the warmest wall available. Campsis needs a sturdy support structure as it becomes very heavy with age. Prune all side shoots back to 2–3 buds from the main framework in late winter. It can be slow to establish but becomes increasingly vigorous and free-flowering with age.

11. Fremontodendron / Flannel Bush (Fremontodendron californicum)

Best for: Warm sheltered walls, architectural planting, very long flowering season Height: 4–6 m against a wall Flowering season: May–October Hardiness: Hardy in sheltered positions; not suitable for cold or exposed gardens

Fremontodendron is a spectacular wall-trained climber that produces an almost unbelievably long succession of large, saucer-shaped, golden-yellow flowers from late spring through to autumn. The flowers have no petals — the colour comes from five large, waxy sepals — giving them a bold, architectural appearance unlike any other garden plant. The lobed, felted foliage is also attractive.

Top varieties:

  • Fremontodendron californicum — The species; bright yellow flowers from May to October.
  • Fremontodendron ‘California Glory’ — A hybrid with larger flowers and a particularly vigorous, free-flowering habit; the most widely grown selection.

Growing tips: Plant in full sun against a south- or west-facing wall in well-drained, even poor soil — rich fertile conditions encourage excessive soft growth at the expense of flowers. Fremontodendron resents root disturbance; plant from a container and avoid transplanting. The hairs on the foliage and stems can irritate skin and eyes — wear gloves and eye protection when pruning.

Choosing the Right Climbing Flower: Key Considerations

1. Aspect and Wall Temperature

The aspect of your wall or fence is critical. South- and west-facing positions receive the most sun and warmth, making them suitable for tender climbers like campsis, passion flower, and star jasmine. North- and east-facing walls are cooler and shadier but are not without options — Rosa ‘Madame Alfred Carrière’, climbing hydrangea (Hydrangea anomala subsp. petiolaris), Clematis ‘Nelly Moser’, and Lonicera x tellmanniana all perform well in these conditions.

2. Support Structure

Different climbers require different types of support. Self-clinging climbers such as campsis attach via aerial rootlets and need no wires or trellis. Twiners like wisteria, honeysuckle, and jasmine need horizontal wires or trellis to wind around. Tendril climbers such as passion flower and eccremocarpus need thin wires or mesh. Roses and fremontodendron need to be tied in manually. Always install supports before or at planting time.

3. Vigour and Available Space

Wisteria and vigorous rambling roses can eventually reach 10 m or more — magnificent on a large house or growing into a mature tree, but entirely impractical against a modest fence panel. Conversely, a compact clematis at 3–4 m is perfect for a small garden obelisk. Always check the ultimate vigour of any climbing plant before purchasing.

4. Fragrance

If fragrance is a priority, prioritise wisteria, honeysuckle, climbing roses, jasmine, star jasmine, and Clematis armandii. Positioned near a door, window, or outdoor seating area, a fragrant climber transforms the character of the whole garden space.

5. Evergreen vs Deciduous

Most flowering climbers are deciduous, losing their leaves in winter. For year-round coverage, consider evergreen options such as Trachelospermum jasminoides, Clematis armandii, and Solanum laxum — bearing in mind that the latter two are not reliably evergreen in hard winters.

Frequently Asked Questions

What is the fastest-growing flowering climber? Among annuals and short-lived plants, eccremocarpus, nasturtium, and Cobaea scandens are the fastest, capable of reaching 3–5 m in a single season. Among permanent hardy climbers, wisteria, campsis, and Lonicera japonica ‘Halliana’ are among the most vigorous.

What flowering climbers grow on a north-facing wall or fence? Rosa ‘Madame Alfred Carrière’, Hydrangea anomala subsp. petiolaris, Clematis ‘Nelly Moser’, Lonicera x tellmanniana, and Jasminum nudiflorum all tolerate or prefer shadier, cooler positions.

What are the most fragrant climbing flowers? Wisteria, summer jasmine (Jasminum officinale), honeysuckle (Lonicera periclymenum), star jasmine (Trachelospermum jasminoides), Clematis armandii, and climbing roses such as ‘Zéphirine Drouhin’ and ‘New Dawn’ are all outstanding for fragrance.

What is the easiest flowering climber to grow? Clematis viticella hybrids, honeysuckle, and climbing roses are all generally reliable and straightforward. Clematis viticella types are particularly easy — they are cut back hard every winter, require no complex pruning decisions, and are highly resistant to clematis wilt.

Can flowering climbers be grown in containers? Yes — clematis, compact climbing roses, passion flower, and jasmine can all be grown in large containers (minimum 40–50 cm diameter) with appropriate support. Regular watering and feeding are essential as container compost exhausts quickly.

How do I prevent a climber from damaging my wall? Self-clinging climbers like campsis can damage soft mortar and painted surfaces over time. For masonry walls, use vine eyes and tensioned horizontal wires set 5–10 cm from the wall surface to allow air circulation and avoid penetrating the masonry. For fences, attach trellis panels with spacers to allow air movement behind.

Climbing flowers are transformative garden plants — capable of turning a blank wall into a living artwork, a bare pergola into a fragrant bower, or a dead tree into a towering floral display. From the unrivalled spectacle of wisteria in full bloom to the long, reliable season of star jasmine, from the intricate beauty of passion flower to the romantic abundance of a climbing rose, the world of flowering climbers is extraordinarily varied.

The key to success is straightforward: choose plants suited to your aspect and climate, provide appropriate support from the outset, and learn when and how to prune each variety. Get these fundamentals right, and your climbing flowers will reward you with a display that improves with every passing season.
