### Thai Basil (*Ocimum basilicum* var. *thyrsiflora*)
**Description:**
Thai Basil has a distinctive flavor profile that combines anise and licorice with a hint of spice. It features small, pointed green leaves with purple stems and vibrant purple flower spikes. It is a staple in Southeast Asian cuisines.
**How to Start from Seed:**
1. Sow seeds indoors 6–8 weeks before the last frost date.
2. Use a seed-starting mix, and plant seeds 1/4 inch deep.
3. Keep the soil moist and maintain a temperature of 70–75°F (21–24°C).
4. Germination takes 5–10 days. Provide bright light or grow under fluorescent lights.
5. Transplant seedlings outdoors after the danger of frost has passed.
**How to Grow in the Garden:**
- **Planting:** Choose a sunny location with well-drained, fertile soil (pH 6.0–7.5). Space plants 12–18 inches apart.
- **Care:** Keep soil consistently moist but not waterlogged. Use mulch to retain moisture and suppress weeds.
- **Maintenance:** Pinch back stems to encourage bushy growth and prevent flowering, which reduces leaf production.
- **Companions:** Grows well with tomatoes, peppers, and marigolds.
**Uses in the Kitchen:**
Thai Basil is ideal for curries, stir-fries, noodle dishes, and soups like pho. It adds a fresh, aromatic flavor when used as a garnish or blended into sauces and pastes.
