Growth Stages

1

Seedling

3-4 weeks

Small cotyledons emerge within 10-14 days; develops true leaves with characteristic elongated shape

Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing early.

2

Vegetative Growth (Year 1)

4-6 months

Low rosette of gray-green, slightly fuzzy leaves develops; plant remains compact and ground-hugging

Water moderately. Remove any flower buds that form to encourage root and leaf development. Mulch lightly after establishment.

3

Overwintering

2-4 months

Plant goes dormant or semi-dormant; rosette persists through winter in most zones

Reduce watering in cool season. Ensure excellent drainage to prevent winter rot. Provide light mulch in zones 3-5 for protection.

4

Flowering (Year 2)

6-10 weeks peak bloom

Tall flower spikes emerge from rosette, reaching 18-24 inches; dense clusters of orange-red and crimson bicolor florets open sequentially

Deadhead spent flowers to extend blooming period. Support tall stems if needed in windy locations. Feed monthly with balanced fertilizer.

5

Seed Production & Decline

4-6 weeks

Flowers fade to seed pods; plant begins to decline after extended flowering period

Allow some flowers to set seed for self-sowing. Remove plant after flowering unless saving seed. New seedlings may emerge for next season.
