Ajuga Alba is a variegated cultivar of common bugleweed, featuring white and green foliage with delicate white flower spikes. This low-growing groundcover spreads via runners and is prized for its ornamental foliage and ability to suppress weeds while adding visual interest to shaded areas. It thrives in cool climates and is particularly valued in woodland gardens and as an edging plant.

Water: Keep soil consistently moist but not waterlogged. Water deeply 1-2 times weekly during growing season. Once established, moderately drought-tolerant but performs best with regular moisture.

📏

Spacing: 12-18 inches apart for groundcover effect inches

📅

Days to maturity: Established flowering in 60-90 days from transplants

🌱

Planting depth: Plant at same depth as root ball; runners should be at soil surface

Soil

Type: Moist, well-draining loamy soil

pH: 5.5-7.0

Growth Stages

Establishment

2-4 weeks

Young plants develop root systems and begin spreading via runners. Foliage is compact and low to the ground.

Water regularly to establish. Remove any dead leaves. Mulch lightly around plants to retain moisture.

Vegetative Growth

6-10 weeks

Plants spread via runners and develop dense foliage mats. White and green variegated leaves become more pronounced. Stolons root at nodes.

Keep soil moist. Thin crowded areas if needed. Remove runners that spread beyond desired boundaries.

Pre-Flowering

2-3 weeks

Flower buds begin to form at the tips of vertical stems rising above the foliage mat. Plants appear fuller and bushier.

Continue consistent watering. Avoid overhead watering which can encourage fungal issues.

Flowering

4-6 weeks (spring to early summer)

Delicate white flower spikes (racemes) bloom above the variegated foliage. Flowers attract pollinators and add vertical interest.

Deadhead spent flowers to encourage continued blooming. Maintain consistent moisture. Provide afternoon shade in warmer zones.

Post-Bloom & Dormancy

8-12 weeks

Flowers fade and seed heads form. In cooler zones, foliage may decline in midsummer heat; in mild zones, growth continues. Preparation for winter dormancy begins.

Cut back flowering stems if desired. Reduce watering slightly in dry periods. Apply mulch in fall for winter protection in zone 3.
