Start by providing moist cold stratification for approximately 6–12 weeks. After chilling, scatter the tiny seeds on the surface of moist, acidic, nutrient-poor growing medium without covering them. Provide bright light and temperatures around 18–22°C. Germination generally takes several weeks, depending on seed quality and growing conditions.
Round-Leaved Sundew naturally grows in nutrient-poor wetlands and acidic bog environments. Tap water can contain dissolved minerals that accumulate in its growing medium and damage sensitive roots. Rainwater, distilled water, or reverse-osmosis water is generally recommended for maintaining healthy growth.
Its rounded leaves are covered with tiny glandular tentacles that produce sticky, dew-like droplets. Small insects become trapped when they land on the leaves. The plant releases digestive enzymes and absorbs nutrients from the captured insects, helping it survive in naturally nutrient-poor environments.
