📏
Spacing: 12-18 inches
📅
Days to maturity: Variable; flowering typically begins in second year from seed (120-180 days to visible blooms)
🌱
Planting depth: Surface sow seeds (requires light to germinate); transplant seedlings at 2-3 true leaves

Soil

Type: Well-draining sandy or gritty loam with excellent drainage
pH: 6.0-7.0
Amendments:
Coarse sand or perlite (50% of mix) Peat moss or coconut coir Small gravel or pumice Avoid heavy clay or moisture-retentive amendments

Growth Stages

1

Seed & Germination

2-4 weeks

Tiny seeds germinate on moist soil surface; first cotyledons appear within 2-3 weeks

Do not cover seeds; provide consistent moisture until germination, then reduce watering. Keep at 65-75°F. Use sterile seed-starting mix to prevent damping-off

2

Seedling

3-6 weeks

Small rosette develops with fine foliage; true leaves emerge after cotyledons

Provide bright light; reduce water frequency as roots develop. Avoid excessive moisture. Transplant to individual pots when 2-3 true leaves appear

3

Vegetative Growth

2-4 months

Compact mound of silvery-gray or green foliage develops; plant establishes root system

Water minimally; allow soil to dry between waterings. Apply balanced low-nitrogen fertilizer monthly if desired. Pinch growth for bushier form if needed

4

Flowering

2-3 months (spring/early summer)

Golden-yellow flowers appear in terminal clusters above foliage; blooms are typically small and abundant

Maintain dry conditions; reduce nitrogen to encourage flowering. Deadhead spent flowers to prolong bloom. Avoid overhead watering to prevent fungal issues

5

Dormancy/Decline

Varies; overwinter indoors in zones below 10b

Growth slows; foliage may fade or withdraw after flowering and during cooler months

Water very sparingly; allow plant to rest. Protect from frost and excessive moisture. Many plants are monocarpic or short-lived; propagate before decline

Common Pests

  • Spray with insecticidal soap or neem oil; isolate affected plants. Remove with alcohol-soaked cotton swab for light infestations

  • Increase humidity slightly; spray with water or use predatory mites. Apply neem oil if severe

  • Remove by hand or treat with horticultural oil. Systemic insecticide if heavily infested

  • Prevent with excellent drainage and minimal watering. Remove affected plant; repot in fresh, sterile soil if salvageable. Improve air circulation

  • Improve air circulation; reduce overhead watering. Apply sulfur dust or fungicide if necessary
