History & Breeding

Arabella Clematis is a hybrid bred by the renowned British clematis breeder Barry Fretwell. Arabella combines the best traits of large-flowered clematis and the herbaceous, non-vining Integrifolia group. This unique genetic background gives the plant its signature disk-shaped blooms and flexible stems, unlike traditional, clinging clematis varieties.

Key Features & Benefits

• Bountiful Blooming: One of the most floriferous clematis, it produces a profusion of flowers—often more than most popular varieties. Its strong, everblooming nature makes it a standout across seasons.
• Eye-Catching Color: The seldom-seen azure-blue hue remains vibrant even as blooms age, shifting through violet and mauve to a soft blue. Central anthers create a striking bicolor effect.
• Versatile Growth: Arabella can be grown as a low, scrambling groundcover, trained up trellises, fences, or obelisks, allowed to spill over low walls and boulders, or used as a ‘spiller’ in containers on patios and decks.
• Ideal Companion: The cool blue flowers complement nearly any color—reds, yellows, oranges, pinks—making it a top choice for pairing with roses, peonies, and vibrant perennials.
• Low Maintenance: Thrives with little fuss. Not prone to clematis wilt, heat and cold hardy, and needs only annual pruning.
• Remontant Habit: When cut back after its first flowering flush, Arabella reliably reblooms within 6 weeks, keeping color in the garden from late spring through fall.

Landscape & Garden Uses

Arabella Clematis is exceptionally versatile and adapts well to a variety of design approaches:

• Groundcover: Its non-clinging, sprawling stems are perfect for scrambling over bare earth, hiding unsightly spots, tree stumps, or around fixtures like water spigots.
• Companion Plant: Plant Arabella among roses, peonies, or other shrubs for a harmonious color palette and contrasting foliage.
• Vertical Accent: With gentle support, it can be clipped upright on a trellis, obelisk, or fence, reaching 5–7 feet and providing a vertical element rich in color.
• Container Star: Ideal for patio planters, where its trailing or climbing habit creates a dynamic display of ever-changing blues up close.
• Border Filler: Works well mixed into perennial borders or used as a ground-hugging rambler at the front of beds.
• Blue or Zen Gardens: Its tranquil hues and lush presence fit beautifully in blue-themed or contemplative Zen garden designs.

Planting Arabella Clematis

Site Selection

• Sunlight: Prefers full sun to partial shade. More sun encourages more blooms, but partial shade helps flowers last longer, especially in hotter climates.
• Soil: Well-draining, fertile soil is best. Amend with compost before planting for optimal growth.
• Protection: Select a site protected from harsh winds. Clematis appreciate cool roots, so mulch or underplant with low-growing perennials.

Planting Steps

1. Dig a hole at least twice the width and depth of the root ball.
2. Incorporate compost or rotted manure into the planting hole.
3. Plant the clematis with the crown 2–3 inches below soil level to encourage healthy shoots and flower production.
4. Backfill, water thoroughly, and mulch generously.
5. Provide a support structure if you wish to train the stems upward.

Care & Maintenance

Watering

• Keep soil consistently moist but not soggy, especially while plants are establishing and during hot weather.

Feeding

• Fertilize in early spring with a balanced, slow-release fertilizer.
• Top-dress with compost or well-rotted manure annually.

Mulching

• Mulch around the base to keep roots cool and retain moisture.

Support

• Arabella is a non-clinging variety with flexible, somewhat scrambling stems. If grown vertically, tie stems gently to supports or weave through trellises or obelisks.

Pruning Arabella Clematis

This clematis falls into the “Green” pruning category, which is for varieties that bloom on fresh growth each year. Pruning keeps the plant tidy and encourages reblooming.

• Prune hard in early spring—cut back all stems to just above a strong node near the base.
• After the first flowering, cut stems back by half to promote a quick rebloom—flowers reappear in as little as 6 weeks.
• Arabella tolerates periodic trimming throughout the season for shape and tidiness.

Pests, Diseases, and Troubleshooting

Common Issues

• Clematis Wilt: Herbaceous types like Arabella are rarely affected by wilt; it is far less susceptible than large-flowered varieties.
• Aphids: May appear on new spring growth. Remove physically by hand or treat with a garlic- or soap-based spray.
• Rabbits: Young shoots are attractive to rabbits—protect new growth with fencing or suitable barriers until established.

General Tips

• Avoid drying out in hot spells.
• Prune back dense foliage or overcrowded areas to improve airflow and reduce fungal risk.
• Ensure supports are strong but not constricting, allowing for easy stem growth.

Design Inspiration: Pairings & Placement

Arabella Clematis offers vast creative opportunities for gardeners and landscape designers:

• Rose Borders: Thread among climbing or shrub roses for a stunning blue-and-pink display.
• Peony Companions: Let wispy stems meander through bold peony clumps, amplifying both plants’ presence.
• Container Gardens: Plant with upright grasses or low-growing evergreens for contrast in shape and texture.
• Garden Features: Camouflage unsightly utilities, tree stumps, or structural anchors with lush, rambling coverage.
• Mixed Borders: Works beautifully with other flowering perennials—think lavender, catmint, or lady’s mantle—for a painterly garden palette.

Frequently Asked Questions (FAQs)

How does Arabella differ from other clematis?

Arabella is a non-clinging, semi-herbaceous variety that sprawls or gently climbs with assistance, unlike traditional twining or vining clematis. Its long flowering time and unique blue color also distinguish it from most other cultivars.

Do I need a trellis for Arabella Clematis?

No, but you may use a support if you wish for vertical growth. Arabella is equally effective as a low groundcover, a spiller over walls/rocks, or for loose layering in beds and borders.

Is Arabella suitable for containers?

Absolutely. Given its compact habit and trailing stems, Arabella is perfect for pots and containers, especially on patios or balconies where flower color can be enjoyed up close.

How tall will it grow?

On the ground as a rambler, expect heights of 2–3 feet and up to 7 feet in spread. With vertical support, it may reach up to 5–9 feet.

Can I encourage more blooms?

Yes! Pruning after the first flush and providing consistent moisture and nutrition promotes new growth and repeated flowering throughout the season.

Is Arabella deer- or rabbit-resistant?

Rabbits are fond of young shoots, so guard new plants. Mature growth is less attractive to pests, but no clematis is fully resistant. Use netting or barriers as needed.
