Audrey Red Rock Cress

Audrey Red Rock Cress (Aubrieta hybrida 'Audrey Red')

Audrey Red Rock Cress is an early-season groundcover that pours bright color over edges, stones, and slopes just as spring begins to wake up. Its low, spreading habit quickly softens hard lines and helps beds look finished with less open soil to manage. The evergreen to semi-evergreen foliage stays attractive beyond bloom, keeping the planting looking tidy even when flowers are gone. If you want dependable spring impact in a small, easy footprint, this rock cress delivers.

Distinctive Features

This variety forms a dense mat of small, gray-green leaves and covers itself in vivid red to red-purple flowers in early to mid spring. Blooms can be so abundant that they nearly hide the foliage, creating a carpet effect that reads well from a distance. The growth is naturally trailing and lends itself to cascading over walls and spilling along borders. Good drainage is essential for long-term vigor, especially in winter and in humid climates.

Growing Conditions

• Sun: Full sun to part shade, with best flowering in full sun.
• Soil: Well-drained soil, ideally gritty or rocky, and it tolerates slightly alkaline conditions.
• Water: Low to medium, water to establish then let soil dry slightly between waterings.
• USDA Zones: Zones 4 to 8.
• Mature Size: Typically 4 to 6 inches tall and 12 to 24 inches wide.
• Habit: Low, mat-forming, trailing groundcover that spreads outward.
• Foliage: Gray-green foliage that is often evergreen in mild winters.
• Bloom Season: Early to mid spring.

Ideal Uses

• Focal Point: Use it as a focal point at the edge of a rock garden where the spring flower carpet can spill over stone.
• Rock Gardens: Tuck into crevices and gritty beds for a natural, cascading spring display.
• Walls and Slopes: Plant along retaining walls or banks to soften hard lines and stabilize light soils.
• Edging: Line sunny borders for a low ribbon of evergreen texture and early color.
• Containers: Use in pots and troughs where it can trail over the rim with spring blooms.

Low Maintenance Care

• Shearing: Shear lightly after flowering to keep the mat dense and encourage fresh growth.
• Watering: Water during prolonged drought, especially in full sun and in containers.
• Drainage: Avoid wet sites and heavy winter moisture by using raised beds or gritty soil mixes.
• Feeding: Fertilize sparingly, since overly rich soil can reduce flowering and loosen the habit.
• Cleanup: Remove winter-damaged foliage in early spring to refresh the planting.
