Lantana camara | Common Lantana

For optimal germination rates, initiate seed propagation indoors under controlled conditions—unless the species exhibits a high sensitivity to root disturbance. This approach allows precise regulation of temperature, humidity, and light, improving germination consistency and seedling viability. Do not skip any recommended seed treatments, as they are essential for uniform and successful germination.

Seed Treatment

  1. Scarification
    • Rub seeds gently with sandpaper or nick the seed coat with a sharp knife.
    • Soak seeds in warm water for 24 hours to soften the hard outer layer.
  2. Cold Stratification
    • Mix seeds with moist sand or peat moss in a plastic bag.
    • Store in the refrigerator (40°F/4°C) for 4–6 weeks before planting.
    • Check weekly: If seedlings sprout in the fridge, remove them gently and plant immediately.

Sowing Instructions

Indoor Sowing (Recommended for Early Start)

  1. Timing: Start seeds indoors 6–8 weeks before the last frost date.
  2. Container: Use seed trays or small pots with a well-draining seed-starting mix.
  3. Planting Depth: Sow seeds ¼ inch (6 mm) deep and lightly cover with soil.
  4. Temperature & Humidity: Maintain a temperature of 70–80°F (21–27°C). 
  5. Light: Place under grow lights for 12–14 hours daily.
  6. Humidity: Use a humidity dome or clear cover to maintain consistent moisture during germination. Open the dome BRIEFLY once per day to allow fresh air in and reduce mold risk. Remove the dome entirely once seedlings emerge.
  7. Watering: Keep soil moist but not soggy. Mist with water if necessary.
  8. Germination Time: up to 120 days AFTER stratification (germination can be slow and erratic).

Direct Sowing (For Warmer Climates)

  1. Timing: Plant outdoors after the last frost, when soil temperatures are above 70°F (21°C).
  2. Location: Choose a full-sun spot with well-drained, sandy, or loamy soil.
  3. Planting Depth: Sow seeds ¼ inch deep and cover lightly with soil.
  4. Spacing: Space plants 12–18 inches apart to allow for bushy growth.
  5. Watering: Keep soil evenly moist until seedlings emerge.

Growing & Care Tips

  • Transplanting: Once seedlings have 2–3 sets of true leaves, transplant them to individual pots or into the garden.
  • Watering: Lantana is drought-tolerant once established but needs regular watering during early growth.
  • Pruning: Trim back leggy growth to encourage a bushy, compact shape.

Fertilization: Use a balanced fertilizer every few weeks to promote flowering.
