Also known as Common Sundew · Dew-Plant · Round-Leaf Sundew
Round-leaved sundew (Drosera rotundifolia) is a carnivorous plant with sticky tentacles to trap insects. It thrives in nutrient-poor, boggy habitats and is recognized for
At-a-glance light, water, soil, and growing conditions from plant data
Bright, Indirect to Full Sun
75% intensity
Requires at least 4-6 hours of direct sunlight or very bright indirect light daily for optimal dew production and coloration.
Keep Consistently Moist
100% intensity
Use distilled, rainwater, or RO water. Maintain a water tray method.
Peat, Sphagnum moss, sand
50% intensity
Moderate (Summer) to Cool (Winter Dormancy)
50% intensity
Enjoys temperatures between 15-25°C during the growing season, with a cooler period (5-10°C) for winter dormancy.
None Required
0% intensity
Naturally obtains nutrients from insects; avoid any soil or foliar fertilization.

Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist, never allowing it to dry out completely. Use distilled, rainwater, or reverse osmosis water.
A good method is to place the pot in a shallow tray filled with about 2-3 cm of water, allowing the peat to wick moisture upwards.
Pruning is generally not necessary for Drosera rotundifolia. Remove dead or dying leaves and flower stalks as they appear to maintain tidiness and prevent fungal issues.
Use clean scissors or tweezers for removal, cutting close to the base of the plant.
Propagation is primarily done through leaf cuttings or by dividing established plants. For leaf cuttings, carefully detach a healthy leaf with its dew-producing stalk and place it on moist peat moss.
Division involves separating the root ball of mature plants into smaller sections.
Repot Drosera rotundifolia every 1-2 years, ideally in early spring before active growth begins. Use a well-draining, nutrient-poor mix, such as a 50/50 blend of sphagnum peat moss and perlite or sand.
Ensure the new pot is deeper than the previous one to accommodate root growth.
