Growth Stages

1

Germination

7-14 days

Seeds sprout with cotyledons appearing; tiny green seedlings emerge

Keep soil moist and warm (65-75°F). Provide bright light immediately upon sprouting. Thin seedlings to prevent crowding.

2

Seedling/Vegetative

3-4 weeks

Small plants develop true leaves and establish root systems; compact growth

Maintain consistent moisture and bright light. Transplant to larger pots when 2-3 true leaves appear. Begin hardening off 7-10 days before planting outdoors.

3

Rosette/Pre-flowering

4-6 weeks

Dense mounding growth with multiple stems forming; foliage is blue-green and strappy

Space plants 12 inches apart. Pinch back growing tips when 4-6 inches tall to encourage bushier, multi-stemmed plants with more flowers. Remove any flower buds that form early to strengthen plants.

4

Flowering

8-12 weeks or more with deadheading

Abundant ruffled flowers in mixed colors appear on long stems; flowers are fragrant and last 2-3 weeks on the plant

Deadhead spent blooms regularly to extend flowering season. Stake tall varieties (18-24 inches) for support. Water deeply but avoid wetting blooms. Feed with balanced fertilizer every 2-3 weeks.

5

Senescence/End of Season

Variable, 2-4 weeks in summer heat; months in cool areas

Flowering slows significantly, especially in hot summer or after first frost; plants may deteriorate

In cool climates, plants may persist into fall and even overwinter. In hot areas, treat as cool-season annual and replant in fall for spring color. Remove dead foliage and plants.

Harvest Tips

Cut flowers in early morning when fully open but before they wilt. Cut stems at a 45-degree angle and place immediately in cool water. Remove lower foliage that would be submerged. Recut stems every 2-3 days and change water daily for longest vase life (10-14 days). Deadhead spent blooms on garden plants to encourage continuous flowering.

Fun Facts
