🌱 Planting Instructions — Anise Hyssop

1. Site Selection

• 
  Sun: Full sun (6+ hours daily) for best blooms. Tolerates very light afternoon shade.
• 
  Soil: Well-drained; prefers loam or sandy loam but tolerates average garden soil if drainage is good.
• 
  pH: Slightly acidic to neutral (6.0–7.5).

2. Planting from Seed Outdoors

• 
  Timing: Sow outdoors after last frost (typically March–April in East Texas).
• 
  Soil Prep: Loosen top 2–3 inches; remove weeds. Work in compost for better fertility.
• 
  Sowing Depth: Lightly press seeds into soil surface; do not cover deeply — they need light to germinate.
• 
  Spacing: Thin or transplant to 12–18 inches apart for airflow and mature size.

Germination:

• 
  Usually 14–21 days if kept moist and temperatures are 60–70°F.
  

3. Starting Indoors (Recommended for Earlier Blooms)

• 
  Timing: Start seeds indoors 6–8 weeks before last frost.
• 
  Light: Provide bright light or grow lights — seeds need light to sprout.
• 
  Temperature: Ideal 65–70°F.
• 
  Transplant: Harden off and move outside once danger of frost is past.

4. Watering

• 
  Water regularly until established.
• 
  Once mature, plants are fairly drought-tolerant but bloom better with moderate watering in prolonged dry spells.
  

5. Maintenance

• 
  Deadhead spent blooms to encourage more flowers and prolong blooming.
• 
  Cut back stems to a few inches above ground after frost in late fall or early winter.
• 
  Divide clumps every 3–4 years if they become crowded.

6. Wildlife & Companion Tips

• 
  Attracts: Bees, butterflies, hummingbirds.
• 
  Deer resistant: Aromatic foliage deters browsing.
• 
  Pairs well with other pollinator-friendly natives like bee balm, blazing stars, and coneflowers.
