Seedling
2-3 weeksTiny seedlings with first true leaves appearing 10-14 days after germination; very delicate with minimal foliage.
Maintain consistent moisture without waterlogging; provide bright light; ensure excellent drainage to prevent damping off. Thin seedlings to reduce competition.
Vegetative Growth
4-8 weeksYoung plant developing dense, compact foliage mats with gray-green to green leaves; no flowers yet. Gradually spreading horizontally.
Water moderately as soil dries; begin hardening off seedlings before transplanting outdoors. Do not overwater or apply excessive fertilizer, which promotes weak growth.
Pre-flowering
2-4 weeks before bloomMature foliage mat fully established; flower buds beginning to form at branch tips in late winter or early spring.
Reduce watering as plant hardens off and prepares for dormancy in autumn. Ensure excellent drainage through winter. Minimal fertilizer needed.
Flowering
4-8 weeksAbundant deep purple-violet flowers covering the foliage mat in dense clusters; peak bloom typically in spring (March-May depending on zone).
Deadhead spent flowers to encourage extended blooming and prevent excessive self-seeding. Water during dry spells. Avoid overhead watering to prevent fungal issues.
Post-flowering & Dormancy
4-6 weeks into summerFlowers fade; plant may produce sporadic blooms into early summer. Foliage remains attractive year-round in most zones; may turn bronze or burgundy in cold.
Allow some flowers to set seed for natural propagation if desired. Cut back or shear lightly after flowering if leggy. Reduce water intake going into winter.
