Seed & Germination
2-3 weeksTiny seeds require light exposure and cool stratification to break dormancy.
Stratify seeds in refrigerator for 4-6 weeks before sowing. Sow on soil surface in spring; do not cover. Keep soil lightly moist until germination (10-14 days).
Seedling
3-4 weeksDelicate seedlings with cotyledons emerge and develop true leaves.
Provide bright light and good air circulation. Water gently to avoid damping off. Thin seedlings to proper spacing. Transplant to well-draining mix when 2-3 true leaves appear.
Vegetative Growth
6-8 weeksPlant develops trailing, spreading stems with palmately lobed foliage and ground-hugging habit.
Establish deep watering routine, then transition to drought conditions. Reduce fertilizer; prefers lean soil. Remove any weeds competing for resources.
Flowering
8-12 weeks (extended with deadheading)Magenta-purple cup-shaped flowers with white centers bloom profusely along trailing stems from late spring through summer.
Deadhead spent flowers to encourage continuous blooming. Provide minimal supplemental water. Avoid high-nitrogen fertilizer which promotes leaf growth over flowers.
Seed Development & Dormancy
4-6 weeksFlowers fade and develop seed capsules; plant gradually stops flowering as temperatures drop in fall.
Allow some flowers to remain for seed formation and self-seeding. Reduce watering further. Plant is cold-hardy; no winter protection needed in hardiness zones.
