Growth Stages

1

Seed germination

7-10 days

Seeds germinate in 7-10 days at warm temperatures (70-75°F). First leaves are rounded cotyledons.

Keep soil moist but not saturated. Provide light (seeds need light to germinate). Maintain warm temperatures.

2

Seedling establishment

2-3 weeks

True leaves emerge; seedlings develop 2-4 sets of leaves. Plants are delicate and small (1-2 inches tall).

Provide bright light indoors. Keep soil consistently moist. Thin seedlings to prevent crowding. Begin light fertilizing at half strength.

3

Vegetative growth

3-4 weeks before planting or until mature

Compact bushy growth with multiple stems forming. Foliage is dense and green; plant reaches 6-12 inches tall.

Harden off transplants gradually before planting outdoors. Pinch back growing tips for bushier growth. Water regularly.

4

Flowering

8-12 weeks (early summer through fall frost)

Dense clusters of distinctive bicolor flowers appear at branch tips. Starry Eyes displays deep colored centers with contrasting lighter star-shaped edges.

Deadhead spent flowers to encourage continuous blooming. Water at soil level. Fertilize every 2-3 weeks with balanced fertilizer.

5

Seed maturation

2-4 weeks after flowering ends

Flowers fade and develop seed pods. In warm climates, may self-seed for next season.

Allow some flowers to remain for seed production if desired. Collect seed pods when papery and dry.
