Diamantina Regal Clematis
Clematis ‘Diamantina’Diamantina Regal Clematis is a striking, large-flowered climbing vine prized for its richly layered double blooms and elegant purple-blue color. From late spring into early summer, it produces large, fully double flowers in deep violet-blue to purple tones with a soft silvery sheen toward the center. A second flush of blooms often appears later in summer, sometimes with slightly simpler flower forms, extending the season of interest well beyond spring.
The blooms are lush, full, and highly ornamental, creating a dramatic vertical display when trained over trellises, fences, obelisks, or arbors. Each flower can reach 4 to 6 inches across, with densely layered petals that give the plant a luxurious, almost rose-like appearance. Its bold color and unusual flower form make it a standout focal point in both formal and cottage-style gardens.
This clematis typically grows 6 to 8 feet tall with a spread of 3 to 4 feet, offering strong vertical interest without overwhelming smaller spaces. The medium green foliage provides a clean, elegant backdrop that allows the richly colored blooms to stand out clearly throughout the season.
Care Instructions:
Planting: Plant in full sun to partial shade with support for climbing, and keep roots cool with mulch.
Soil: Use fertile, well-drained soil enriched with organic matter.
Watering: Water regularly during establishment and maintain even moisture during active growth.
Fertilizing: Apply a balanced fertilizer in early spring and after the first bloom if needed.
Pruning: Light pruning in late winter or early spring; remove weak stems and shape after flowering.
Spacing: Space plants 3–4 ft apart for mature growth and airflow.
Maintenance: Provide support and mulch around the root zone.
Diamantina thrives in full sun to partial shade and prefers fertile, well-drained soil with consistent moisture. Like most clematis, it performs best when the roots are kept cool and shaded while the upper growth receives plenty of sunlight. Mulching around the base or planting low-growing companions helps protect the root zone and improves long-term performance.
Its double blooms, rich color, and repeat flowering make Diamantina Regal Clematis an excellent choice for gardeners looking to add elegance, texture, and long-lasting vertical beauty to the landscape.
