Vegetative Growth
Spring through early summer, 8-12 weeksStolons (runners) spread rapidly, foliage deepens in color and becomes more abundant, forming dense ground cover mats
Allow runners to spread. Remove weeds that compete with young growth. Deadhead spent flowers if desired to encourage foliage development.
Flowering
4-6 weeks, typically April-June depending on zoneUpright flower spikes emerge from the foliage mat, bearing dense whorls of small blue-violet tubular flowers
Flowers attract pollinators. Deadhead spent spikes to extend blooming or allow to go to seed for self-sowing. Light fertilization with balanced fertilizer can encourage more blooms.
Seed Set & Summer
6-10 weeksFlowers fade to seed pods; foliage remains lush and purple-bronze throughout summer. Plant continues spreading via stolons
Reduce watering as summer heat increases; drought stress won't harm established plants. Keep area weeded. Shear back if growth becomes unruly.
Fall & Winter
Ongoing through seasonFoliage retains deep purple color and remains evergreen. Growth slows in late fall; plant becomes dormant in winter
Generally requires little care. In very cold zones, a light mulch can protect from freeze-thaw cycles. Remove any winter-damaged foliage in early spring.

Fun Facts
- 🌱 Ajuga 'Atropurpurea' gets its name from 'atro' (very dark) and 'purpurea' (purple), describing its distinctive deep purple-bronze foliage that intensifies with sun exposure.
- 🌱 The common name 'Bugleweed' comes from the resemblance of its flower spikes to a bugle or trumpet, and historically it was used to make musical instruments.
- 🌱 Ajuga is native to Europe and has naturalized in many regions; it spreads via stolons (runners) much like a strawberry plant, allowing a single specimen to eventually cover several square feet.
