Establishment (Transplant)
4-6 weeksYoung plant settling into garden with initial silvery-green foliage; minimal flowering as energy goes to root development
Water regularly for first 4-6 weeks to establish roots. Mulch lightly around base (not touching stem). Avoid fertilizing heavy nitrogen.
Vegetative Growth
6-8 weeksPlant develops fuller foliage structure with branching; silvery-green leaves expand and plant widens
Pinch back tips in early growing season to encourage bushier form. Maintain moderate water. Light feeding with balanced or bloom-promoting fertilizer.
Flowering (Spring-Summer)
12-16 weeksAbundant spikes of deep raspberry-red flowers with dark burgundy calyces emerge; continuous bloom in cooler climates
Deadhead spent flower spikes to encourage continuous blooming. Keep soil consistently moist but not wet. High-potassium fertilizer supports prolonged flowering.
Peak Bloom & Pollinator Activity
6-10 weeks (summer peak)Plant at full flowering with dense flower coverage; hummingbirds and bees actively visiting; rich color display
Minimal intervention; allow some flowers to remain for wildlife. Monitor for spider mites in dry heat. Ensure adequate water during hot spells.
Fall Decline & Dormancy
Variable by climate; 8-16 weeksFlowering slows as temperatures cool; foliage may become slightly less vibrant; plant enters semi-dormant state in winter
Reduce watering significantly. In zone 8, provide frost cloth during hard freezes. Light pruning after first frost to shape. No fertilizing in fall/winter.
