Seed Dormancy & Stratification
4-8 weeks or natural winter dormancySeeds require cold moist stratification to break dormancy and germinate properly.
Stratify seeds outdoors in fall or refrigerate moist seeds for 4-8 weeks before spring planting. Can also direct sow in fall for natural stratification.
Seedling & Rosette Formation
4-8 weeksYoung plants develop a basal rosette of deeply lobed leaves close to the ground.
Keep soil consistently moist but not waterlogged during establishment. Protect from foot traffic. Thin seedlings to appropriate spacing.
Vegetative Growth
8-12 weeksPlants develop larger rosettes and begin sending up flowering stems. Foliage is deeply pinnate and somewhat sticky-glandular.
Gradually reduce watering as plants mature. Ensure excellent drainage to prevent root rot. Mulch lightly if needed.
Flowering
4-8 weeks (late May through July, depending on location)Plants produce multiple pink to magenta daisy-like flower heads (2-3 inches across) with yellow centers on sturdy stems above the foliage.
Deadhead spent flowers to encourage continued blooming if desired, though plants are often left natural. Do not overwater during flowering.
Seed Development & Dormancy
6-10 weeks through fallFlowers fade and develop seeds in papery seed heads. Plants prepare for dormancy as day length decreases.
Allow flowers to remain on plant if self-seeding is desired. Cut back dead stems in fall or spring. Very minimal water needed.
