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
Soak seeds in lukewarm water for 1–2 hours to soften the seed coat and promote faster, more uniform germination.
When to Sow
Indoors: Start seeds 42–56 days (6–8 weeks) before the last expected frost.
Outdoors: Direct sow only in late spring after all danger of frost has passed. Outdoor sowing is not recommended for best germination results.
Germination Conditions
Temperature: Maintain 18–22°C (64–72°F) for best results.
Germination Time: 7 to 30 days
Light: Seeds require light to germinate. Do not cover.
Use grow lights to maintain 12–16 hours of light per day.
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.
How to Sow Indoors
- Fill trays or pots with a well-draining seed-starting mix.
- Lightly press seeds into the surface of pre-moistened soil. Do not bury.
- Mist gently to settle the seeds in place.
- Cover with a humidity dome and provide bright light and warmth.
Post-Germination Care
Once seedlings emerge, remove the humidity dome and keep under bright light or grow lights. Water carefully to keep the soil moist but not soggy.
Final Spacing: 20–25 cm (8–10 in) apart
Growth Habit: Low-growing, spreading perennial groundcover
Mature Height: 10–15 cm (4–6 in)
Type: Perennial
Growing Tips: Thrives in full sun and well-drained, sandy or rocky soil. Drought-tolerant once established. Trim back lightly after flowering to maintain compact growth.
