Establishment
4-6 weeksYoung plants develop rosettes of dark purple foliage and establish root systems. Growth is compact and low.
Keep soil consistently moist for first 4-6 weeks. Mulch around plants to retain moisture and prevent weeds. Avoid overwatering.
Vegetative Growth
3-4 monthsPlants spread via runners (stolons) and fill in surrounding space. Foliage becomes more robust and color deepens, especially in cool weather.
Water moderately. Deadhead spent flowers if desired to encourage vigor. Allow runners to spread naturally or redirect them. Light fertilizing in spring promotes growth.
Flowering
3-4 weeksViolet-blue flower spikes emerge from the foliage, creating a striking contrast with the dark purple leaves. Blooms typically appear in mid to late spring.
No special care required during flowering. Deadheading extends bloom period but is optional. Flowers attract pollinators.
Post-Bloom
Ongoing through growing seasonFlowers fade and foliage remains attractive. The plant continues to spread and fill in areas. Foliage color may become less intense in summer heat.
Cut back leggy growth if needed to maintain neat appearance. Ensure adequate water during hot, dry spells. The plant goes dormant or semi-dormant in winter.
Dormancy
Variable; 2-4 months depending on climateIn winter or during summer heat stress, plants may reduce growth. Foliage remains evergreen in milder climates but may brown in harsh winters.
No watering needed in winter (unless in areas with winter rain). Avoid heavy foot traffic. In spring, remove any dead foliage. Divide congested plants in early spring or fall.
