Growth Stages

1

Seedling

2-3 weeks

Small seedlings with 2-4 true leaves emerge from seeds

Keep soil moist but not waterlogged. Provide bright light indoors. Thin seedlings to proper spacing once true leaves appear.

2

Vegetative

3-4 weeks

Plant develops into a compact, bushy mound with multiple stems and linear, blue-green foliage

Ensure full sun exposure. Pinch growing tips early to encourage bushier growth. Water moderately; apply balanced fertilizer every 3-4 weeks.

3

Flowering

8-12 weeks or until frost

Abundant neon pink flowers with dark burgundy or purple centers appear at stem tips

Deadhead spent flowers regularly to promote continuous blooming. Maintain consistent watering without wetting foliage. Apply low-nitrogen fertilizer to encourage flowers over foliage.

4

Peak Bloom

4-8 weeks

Plant is covered in numerous vibrant neon pink blooms creating a striking display

Continue deadheading daily or every other day for maximum blooms. Monitor for pests and disease. Keep soil moisture consistent.

5

Decline

Variable, until killing frost

Flowering slows as temperatures rise (in heat) or as frost approaches in fall

Continue deadheading to extend season. In hot climates, provide afternoon shade. Plant decline signals end of season or need for cool-season rest.
