4-6 weeksYoung plants develop rosette formations with small dark green leaves and establish root systems
Water moderately during first 4-6 weeks to establish roots, then reduce watering significantly. Plant in well-draining soil with excellent drainage
Vegetative Growth
Ongoing through growing seasonPlant expands horizontally, forming dense mounding clusters of rosettes with characteristic dark green foliage
Minimal watering needed. Allow soil to dry completely between waterings. No fertilizer needed; actually thrives in poor soil
Flowering
6-8 weeks, typically March-May depending on zoneIn spring, plants produce tall stems topped with distinctive yellow-green flower bracts (not true flowers) arranged in dense, showy clusters
No special care needed. Flowers appear reliably on established plants. Bracts last 4-6 weeks
Post-Flowering
Until fall/winterFlower stems fade and can be removed; plant continues spreading as ground cover. Foliage remains vibrant and attractive year-round
Deadhead spent flower stems if desired for neatness, though not necessary. Continue drought-tolerant watering schedule
Winter Dormancy
3-4 monthsIn cooler zones (7-8), foliage may darken or take on bronze tones; plant slows growth but remains evergreen in most conditions
