Seedling
2-3 weeksTiny seedlings with 2-4 true leaves emerge within 7-10 days. Plants are delicate but grow steadily.
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlants develop bushy foliage with multiple stems, reaching 6-10 inches tall. Leafy, compact growth with no flowers yet.
Water regularly and pinch back growing tips when plants are 4-6 inches tall to encourage bushier growth. No fertilizer needed if soil is adequate.
Bud Formation
2-3 weeksMultiple flower buds appear at stem tips. Plants reach full height of 12-16 inches with dense branching.
Continue regular watering. Apply light fertilizer (low-nitrogen) if desired. Remove any diseased foliage.
Flowering
6-10 weeks (extends with deadheading)Profuse double flowers in mixed colors (pink, purple, red, white) bloom continuously from buds. Peak ornamental stage.
Deadhead spent blooms regularly to encourage continued flowering. Water during dry spells. Stake taller stems if needed in windy areas.
Seed Production
3-4 weeksIf flowers are left to mature, they develop seed heads with distinctive spiky bracts. Plants may decline if heavily seeded.
Allow some flowers to go to seed for self-sowing next year, or deadhead all blooms to extend flowering. Cut seed heads before they fully dry if you want to collect seeds.

Harvest Tips
Cut flowers in early morning after dew dries but before heat of day for longest vase life. Harvest when blooms are just fully open. Cut stems at an angle using clean shears, removing at least half the stem. Recut stems indoors and place in fresh water immediately. For dried arrangements, harvest flowers when fully open and dry them upside-down in bundles in a dark, airy location.
