Artemisia absinthium (Wormwood)

Also known as Wormwood, this aromatic herb is valued for its silvery foliage and traditional medicinal use. Easy to grow and drought-tolerant once established!

SEED PREPARATION

  • Cold Stratification: Place seeds on a damp paper towel inside a plastic bag. Refrigerate for 2–4 weeks.
    ---- If seeds sprout during stratification, carefully remove and plant them immediately.

WHEN & WHERE TO SOW

  • Indoors: Start seeds 6–8 weeks before the last frost.
  • Outdoors: Sow directly in late spring after the danger of frost has passed.
  • Light Requirement: Full sun
  • Soil: Well-draining, sandy or loamy soil with neutral to slightly alkaline pH (6.5–7.5)

SOWING INSTRUCTIONS

  • Surface Sow: Do not cover seeds – they need light to germinate.
  • Spacing: Thin or transplant seedlings 30–60 cm (12–24 in) apart.
  • Watering: Keep the soil evenly moist but not soggy until germination.

GERMINATION CONDITIONS

  • Ideal Temperature: 20–22°C (68–72°F)
  • Germination Time: 14–28 days (AFTER stratification)
  • Be patient, germination can be slow and uneven.

POST-GERMINATION CARE

  • Light: Provide strong light or grow under fluorescent grow lights if started indoors.
  • Water: Water moderately; avoid overwatering.
  • Hardening Off: Gradually acclimate seedlings to outdoor conditions before transplanting.
  • Maintenance: Once established, Wormwood is drought-tolerant and thrives on neglect. Trim back in early spring to maintain shape and vigor. Avoid overly rich soil, which can reduce aroma and strength.

TIP: Artemisia repels certain pests and can be used as a natural companion plant—but do not plant near food crops as it may inhibit their growth.
