Growth Stages

1

Seedling

2-3 weeks

Tiny green shoots emerge with cotyledons; initial leaf development begins

Maintain consistent moisture and bright light. Keep soil warm (70°F ideal). Thin seedlings to prevent crowding.

2

Vegetative Growth

6-8 weeks

Compact plant develops rosette of deeply lobed green foliage; bushy growth habit

Water regularly, fertilize every 4 weeks with balanced fertilizer. Pinch back tips early in season to encourage bushier growth and earlier flowering.

3

Bud Formation

2-3 weeks

Flower buds appear at stem tips; plant reaches full compact size

Maintain consistent watering. Reduce nitrogen fertilizer, switch to higher phosphorus formulation (e.g., 5-10-5) to promote flowering.

4

Flowering

6-8 weeks (June-August)

Large double white flowers with yellow centers bloom prolifically; flowers measure 2-3 inches across

Deadhead spent blooms regularly to promote continued flowering. Water at base, avoid wetting petals. Stake if needed in windy locations.

5

Post-Bloom & Dormancy

Variable, extends into winter

Flowers fade, foliage may yellow in late summer; plant enters dormancy in fall

Cut back stems to 3-4 inches in fall after frost. Apply 2-3 inches of mulch for winter protection in colder zones. Divide every 3-4 years to rejuvenate.

Harvest Tips

Cut flowers in early morning after dew dries, when blooms are fully open but buds still present on the stem. Use sharp scissors to cut stems at 45-degree angle, leaving at least 6 inches of stem on the plant. Remove lower leaves from cut stems.
