Germination & Seedling
3-4 weeksSeeds germinate within 1-3 weeks. Seedlings develop true leaves and establish a taproot system.
Keep soil lightly moist but not wet. Provide bright light. Use well-draining seed-starting mix. Avoid damping off by ensuring good air circulation.
Young Plant Establishment
6-12 monthsPlant develops multiple stems and grows slowly, establishing a deep root system. Foliage is sparse and growth is gradual.
Water sparingly; allow soil to dry between waterings. Provide full sun. Do not fertilize excessively; this species prefers lean soil. Stake if necessary in windy conditions.
Vegetative Growth
6-12 monthsPlant becomes bushier with more branches and foliage. Growth accelerates during the warm season. Stems become woody and lignified.
Continue minimal watering; drought conditions actually improve flower production. Full sun is critical. Light pruning can shape the plant. Reduce water in cooler months.
Flowering
8-10 weeks (peak); can flower multiple times per year in warm climatesPink to mauve flowers with deep red or burgundy centers appear on new growth. Flowers are cup-shaped and typically 2-3 inches across. Blooming is prolific in ideal conditions.
Maintain low water regime for best flowering. Full sun exposure is essential. Do not over-fertilize. Deadheading encourages more blooms but leave some flowers for seed development.
Seed Pod Development & Maturity
8-12 weeks for pod maturationAfter flowering, distinctive, decorative seed pods develop. Pods turn brown and woody as seeds mature. Plant may enter dormancy in cooler months.
Allow pods to mature on plant for ornamental interest or seed collection. Reduce watering during dormant season. Harvest seed pods when fully brown and dry.
