Complete Plant Information
Overview
Rosa ‘Interdust’ SUN RUNNER is a compact, hybrid Shrub rose highly valued for its dense growth habit, making it function excellently as a ground cover rose. This cultivar boasts showy clusters of fragrant, bright yellow blossoms that appear continuously from May until the first hard frost. As a member of the sprawling Shrub rose category, Rosa ‘Interdust’ SUN RUNNER offers reliable color and texture for mass plantings or slope stabilization.
This variety typically maintains a low profile, growing roughly 1 to 1.5 feet tall but spreading 2 to 3 feet wide, creating a durable, horizontally oriented blanket of color. While it appreciates full sun for the best flowering performance and disease resistance, it can tolerate some light shade. Proper cultural techniques are essential to manage the medium maintenance needs associated with this lovely introduction.
Gardeners seeking a low-growing option that provides long-lasting blooms will find Rosa ‘Interdust’ SUN RUNNER particularly rewarding. Its density helps suppress weeds and its relatively small stature avoids overshadowing smaller border plants. Utilize this colorful Shrub rose throughout your landscape where consistent, low-maintenance yellow provides year-round interest.

How to Grow
For best results, plant Rosa ‘Interdust’ SUN RUNNER in well-drained garden loams that have slightly acidic soil conditions. While full sun maximizes flowering and disease defense, this Shrub rose will adapt to sites receiving partial shade. Planting during the dormant season (late winter or early spring, depending on freeze dates) generally allows for the best establishment before summer heat arrives.
Once established, maintain medium moisture levels, watering deeply and consistently, preferably in the mornings to allow foliage to dry thoroughly before evening. Avoid overhead watering, as this can encourage fungal issues. Good air circulation is vital for healthy growth; ensure adequate spacing between Rosa ‘Interdust’ SUN RUNNER plants to promote airflow and help control foliar diseases. Applying a summer mulch helps retain soil moisture and keeps the roots cool.
Routine care involves removing spent flowers throughout the season to encourage maximum rebloom, a process known as deadheading. In colder limits of its range, such as Zone 5 conditions (like St. Louis), the crowns of your Rosa ‘Interdust’ SUN RUNNER may require winter protection. Prune minimally as needed in late winter or early spring to shape the plant or remove any dead wood. Always clean up and destroy fallen leaves, especially during the dormant season, to reduce overwintering disease spores.
Landscape Uses
The sprawling, ground-hugging nature of Rosa ‘Interdust’ SUN RUNNER makes it an exceptional choice for mass plantings, creating a spectacular, carpet-like effect when covered in bright yellow blooms. This Shrub rose is highly functional, proving beneficial for stabilizing various landscape elements, including embankments, steep banks, or retaining walls where its root system helps bind the soil. Its low profile also makes it suitable for planting along curbsides where height restrictions are important.
Consider using large drifts of this low-growing Shrub rose as a striking low border against taller shrubbery or foundation plantings. Because it blooms so prolifically, utilize it in areas where high impact color is desired without the vertical bulk of traditional rose bushes. While not explicitly noted as a container plant, its small size suggests it could perform well in large, shallow containers if managed carefully for moisture retention.

Noteworthy Characteristics
Rosa is a genus noted for beautiful, often fragrant, single to double flowers on often prickly stems. SUN RUNNER is specifically a small, hybrid Shrub rose that grows horizontally rather than vertically, often sold as a ground cover rose, reaching only 1-1.5 feet tall and 2-3 feet wide. It features ten-petaled, fragrant, bright yellow blossoms about 1.5 inches across, blooming initially in May with continuous repeat flowering into the fall, backed by dark green foliage.
Tolerances
- Erosion
Potential Problems
Roses, including Rosa ‘Interdust’ SUN RUNNER, are susceptible to several common diseases such as black spot, powdery mildew, and rust. Fungal issues are exacerbated by high humidity and lack of air circulation. Insect pests like aphids, spider mites, and scale may also appear. Good cultural practices are the primary defense; water at the base of the plant in the morning and ensure pruning allows for excellent air flow. In humid areas, preventative fungicide applications throughout the growing season are frequently necessary for best disease control. Always remove and destroy diseased leaves promptly during the growing season and during the dormant cleanup.

Companion Planting
When selecting companions for your Rosa ‘Interdust’ SUN RUNNER, focus on plants that share similar light and water needs (medium moisture, full sun to part shade). Low-growing perennials that offer contrast in texture or color work wonderfully beneath the arching stems of this Shrub rose. Consider pairing it with Lamb’s Ears (Stachys byzantina) for silvery, contrasting foliage texture, or use creeping thyme (Thymus serpyllum) as an aromatic, drought-tolerant ground cover filler between the rose clumps.
Excellent companions that thrive in similar well-drained loam include ornamental grasses like Blue Fescue (Festuca glauca), which provide slender, cool-toned vertical accents near the low-growing rose. Ensure that any companion planting scheme maintains excellent air circulation around the base of the roses to help mitigate potential foliar diseases common to this genus.
Seasonal Care Calendar
Spring preparation for your Rosa ‘Interdust’ SUN RUNNER begins in late winter or early spring with pruning, removing any blackened or damaged canes before the sap starts to flow. As the growing season kicks off, apply a balanced, slow-release rose fertilizer according to package directions to fuel continuous blooming through summer. In the heat of mid-summer, focus heavily on deep, consistent watering, especially during dry spells, ensuring water goes to the root zone, not the foliage.
As autumn approaches, deadhead spent blooms regularly to encourage the final flush of color that extends the season right up to the first frost. After the leaves drop and dormancy approaches, a critical step for cold-climate success is providing winter protection for the crowns; consider mounding soil or applying heavy mulch around the base of the Shrub rose. Final cleanup of fallen leaves must occur before winter sets in to ensure a healthier start next spring.
