Eclipta prostrata, commonly known as False Daisy, is a fast-growing annual or short-lived perennial herb in the Asteraceae family, native to tropical and subtropical Americas and now naturalized worldwide. Seeds are strongly photoblastic and require light to germinate, with no dormancy period, making them easy to establish from seed. The species is highly adaptable and tolerant of various environmental conditions, preferring moist soils and warm temperatures.

Tips
Seeds are strongly photoblastic and must not be covered—ensure they remain on or near the substrate surface for optimal germination. Maintain consistently moist (but not waterlogged) substrate and provide warm temperatures between 25-30°C for fastest germination. Germination typically occurs within 7-14 days under ideal conditions. Keep good air circulation to prevent fungal growth. Seedlings can be transplanted once 2-4 true leaves develop. This species is fast-growing and highly productive, capable of generating thousands of seeds per plant. Alternating day/night temperatures improve germination rates. Soil should be well-draining and pH can range from acidic to slightly alkaline (6.0-7.5).
