Asao Clematis

Asao Clematis (Clematis 'Asao')

Asao Clematis brings a refined, romantic look to the garden with large pink flowers that brighten vertical spaces from late spring into the warmer months. Its soft yet vivid bloom color makes it especially effective near patios, entryways, and garden seating areas where the flowers can be enjoyed up close. This variety gives you the classic appeal of a large-flowered clematis while still fitting comfortably into residential landscapes with trellises, arbors, and decorative supports. For gardeners who want a climbing plant with elegance, repeat bloom, and strong visual presence, Asao is a rewarding choice.

It is especially valuable when a garden needs height without feeling too heavy or overgrown. The flowers have a luminous quality that stands out beautifully against green foliage and darker background plantings. Because it blooms more than once in a season, it helps carry the display well beyond the first flush of spring color. When you want a vine that feels polished, memorable, and full of garden character, Asao is an excellent fit.

Distinctive Features

Asao Clematis is a deciduous climbing vine known for its large flowers in warm pink to rosy pink shades, often with a deeper pink central bar and contrasting pale to creamy stamens. The first flush appears in late spring to early summer on older stems, with a second lighter flush later in summer on new growth. The blooms are broad and showy, giving the plant strong ornamental value even from a distance. Its combination of generous flower size, rich pink coloring, and repeat bloom has made it a long-standing favorite among large-flowered clematis selections.

Growing Conditions

• Sun: Plant in full sun to partial shade, with the best performance often coming from good light on the vine and cooler, shaded roots.
• Soil: Grow in fertile, moist, well-drained soil enriched with organic matter for steady growth and flowering.
• Water: Provide regular water to keep the soil evenly moist, especially during establishment and in hot or dry periods.
• Zones: This clematis is generally hardy in USDA Zones 4 to 8.
• Deer Resistance: Deer resistance is often considered moderate, though browsing can still occur where pressure is high.

Ideal Uses

• Trellises: Use it on trellises, fences, and lattice panels where the large pink flowers can be shown at eye level.
• Arbors: This variety is well suited to arbors and entry structures where it can create a welcoming seasonal display.
• Patio Gardens: Plant it near outdoor living spaces where the flower color and detail can be enjoyed up close.
• Mixed Vertical Plantings: Let it climb with companion shrubs or roses where its pink flowers can add softness and contrast.
• Focal Point: Use Asao Clematis as a focal point on a trellis or arbor where its large pink flowers can anchor the vertical planting and draw attention through the season.

Low Maintenance Care

• Watering: Keep the root zone evenly moist, especially during the first growing season and during extended dry spells.
• Mulching: Apply mulch around the base to help keep roots cool and maintain more consistent soil moisture.
• Pruning: Prune lightly in late winter or early spring, removing weak or damaged stems while preserving strong framework growth for the early bloom cycle.
• Feeding: Feed in spring with a balanced fertilizer to support healthy growth and repeat flowering.
• Support: Provide a trellis or similar support early so new growth can climb and display flowers cleanly.
