About Round-leaved sundew
Drosera rotundifolia, commonly known as the round-leaved sundew, is a small perennial carnivorous plant forming a basal rosette of sticky leaves. Its leaves, covered in bright red glandular tentacles, trap insects for nutrients. It is ideal for humid terrariums, bog gardens, or as an indoor plant in a controlled environment.
Native range
North America, Europe, and Asia
Care tips
It requires full sun or bright indirect light for at least 6 hours a day to maintain its vibrant coloration. Watering should be constant with distilled, rainwater, or reverse osmosis water, keeping the substrate always moist and preferably with the pot sitting in a tray with a little water. Use a nutrient-poor substrate such as pure sphagnum peat moss or a mixture of peat and quartz sand. Avoid fertilizing or using tap water, as its roots are very sensitive to minerals and salts.
