Leonotis nepetifolia Seed Germination Guide Overview Leonotis nepetifolia (lion’s ear, klip dagga) is a fast-growing annual/short-lived perennial valued for tubular orange flowers that attract pollinators. Seeds are easy to start from seed with a few simple steps for fast, reliable germination. Supplies Fresh seeds Fast-draining seed-starting mix Trays or small pots with drainage Clear dome or plastic cover (optional) Spray bottle or fine mister Heat mat (optional; speeds germination) Seed Preparation No strict dormancy: seeds generally do not require scarification or stratification. Optional pre-soak: soak seeds in lukewarm water for 4–12 hours to soften seed coat and speed germination (not necessary but helpful). Sowing Methods (choose one) Indoors (recommended for earlier blooms) Timing: sow 6–8 weeks before last expected frost. Depth: press seeds onto surface or cover lightly with 1/8" (3 mm) of seed-starting mix—very shallow, as light aids germination. Temperature: maintain soil temperature 70–78°F (21–26°C); use a heat mat for best results. Moisture: keep medium evenly moist but not soggy; mist surface to avoid displacing seeds. Light: provide bright light or grow lights immediately—seeds are light-responsive. Germination time: typically 7–21 days. Direct-sow outdoors Timing: sow after last frost when soil has warmed and nighttime temps are consistently above ~55°F (13°C). Site: well-draining soil in full sun. Depth: scatter seeds and press lightly into soil or cover with a very thin layer (≤1/8"). Spacing: thin or transplant to 12–18" (30–45 cm) between plants once established. Germination time: 7–21 days, depending on temperature and moisture. Seedling Care & Potting On Light: seedlings need bright light to avoid legginess—use grow lights if indoors. Water: keep evenly moist; avoid waterlogged conditions. First true leaves: transplant to individual pots when seedlings show 2–3 true leaves. Harden off: acclimate seedlings outdoors 7–10 days before transplanting to garden. Transplanting & Spacing Transplant outdoors after last frost and once seedlings are hardened off. Final spacing: 12–18" (30–45 cm) between plants for good air flow and bloom production. Soil: well-draining, moderately fertile; tolerates poorer soils but flowers best with moderate fertility. Troubleshooting Poor germination: check seed freshness, temperature (too cold slows germination), and consistent moisture. Damping-off: avoid overwatering, use clean mix, provide good airflow, and avoid overcrowding. Leggy seedlings: increase light intensity and reduce distance to light source. Quick checklist Sow shallow (surface or ≤1/8" cover). Keep soil 70–78°F (21–26°C) and evenly moist. Provide bright light from day one. Germination: 7–21 days. Transplant at 12–18" spacing after hardening off.
