Artemisia ludoviciana (White Sagebrush, Western Mugwort)

Seed Treatment (Cold Stratification Recommended)

Cold Stratification Steps:

  1. Place seeds in a moist paper towel, or mix with damp sand or vermiculite.
  2. Seal in a plastic bag and refrigerate at 35–40°F (1–4°C) for 2–4 weeks.
  3. Check weekly to ensure moisture is consistent (not soggy or dry).
  4. After stratification, sow immediately.

Sowing Instructions

  1. When to Sow:
    • Indoors: Start seeds 6–8 weeks before your last expected frost date.
    • Outdoors: Direct sow in late fall (for natural stratification) or early spring.

  2. Soil Requirements:
    • Thrives in well-draining, sandy or rocky soil.
    • Tolerates poor, dry conditions once established.
    • Ideal pH: 6.0–7.5.

  3. Light Requirements:
    • Requires full sun (6+ hours daily) for best growth and silvery foliage.

  4. Sowing Depth:
    • Surface sow seeds — do not cover, as they need light to germinate.
    • Gently press into the soil for good contact.

  5. Watering:
    • Keep the soil evenly moist during germination.
    • Once established, very drought-tolerant — avoid overwatering.

  6. Germination Time:
    • Germinates in 14–21 days under ideal conditions at 65–70°F (18–21°C).

  7. Spacing:
    • Thin or transplant seedlings 18–24 inches (45–60 cm) apart to allow room for spreading.

Growing Tips

  • Artemisia ludoviciana is a fragrant, silvery-leaved perennial valued for its drought tolerance, deer resistance, and wildlife habitat value.
  • Spreads by rhizomes — plant where it can naturalize or be controlled.
  • Ideal for xeriscapes, pollinator gardens, borders, and medicinal herb gardens.
  • Trim back in spring to encourage new growth and compact form.
  • Can be used fresh or dried in aromatherapy, smudge sticks, and natural insect repellents.
