Seedling
2-3 weeksTiny leaves emerge with cotyledons; plant is fragile and low-growing
Keep soil consistently moist but not waterlogged. Provide bright light and maintain 65-70°F. Thin seedlings to prevent damping off.
Vegetative Growth
8-10 weeksBushy foliage develops with multiple stems branching out; plant becomes fuller and mounding
Pinch back stem tips in early summer (by late June) to encourage branching and a fuller shape. Water regularly. Apply balanced fertilizer monthly.
Pre-flowering (Bud Formation)
3-4 weeksBuds begin forming at stem tips in late August; visible color appears in bud clusters
Reduce nitrogen fertilizer to encourage flowering over foliage. Maintain consistent moisture. Remove any dead or diseased stems.
Flowering
6-8 weeksProlific deep purple-violet daisy-like flowers open from late September through November; plant becomes a mass of color
Deadhead spent flowers to prolong blooming. Stake if needed for tall growth. Continue regular watering but avoid overhead watering.
Senescence & Dormancy
December-MarchFlowers fade and seed heads form; foliage may discolor as temperatures drop
Allow seed heads to remain for wildlife food and winter interest. Cut back dead stems to 3-4 inches in spring after last frost. Divide every 3 years.
