Seedling
2-3 weeksTiny green cotyledons emerge; first true leaves develop with characteristic palmate shape
Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Thin seedlings to prevent damping off.
Vegetative/Establishment
4-8 weeksLow mounding growth with lobed basal leaves; plant builds root system and foliage mass
Water regularly during establishment. Mulch around base to retain moisture and suppress weeds. No fertilizer needed if soil is reasonably fertile.
Flowering
8-12 weeks (repeated cycles)Delicate white flowers with pink veining emerge on thin stems above foliage; profuse blooming from early summer through fall
Deadhead spent flowers to encourage continuous blooming. Water during dry spells. Avoid excessive nitrogen which reduces flowers.
Late Summer/Fall
4-8 weeksContinued flowering may slow slightly; foliage remains attractive; plant consolidates energy
Continue deadheading if wanting extended blooms. Reduce watering slightly as temperatures cool. Plant will self-seed if flowers are left to mature.
