Drosera rotundifolia aka Round Leaf Sundew

Taxonomy

Drosera rotundifolia, also known as the round-leaved sundew, roundleaf sundew, or common sundew, is a carnivorous perennial plant that thrives in bogs, marshes, and fens. It has a circumboreal distribution, found across northern Europe, Siberia, northern North America, Korea, Japan, and even as far south as California, Mississippi, Alabama, and New Guinea. This captivating plant forms basal rosettes of long-stalked leaves, with almost circular leaves measuring up to 1cm in diameter. These leaves are covered in sticky, red-tipped, gland-bearing hairs that trap small insects. The leaves are supported by horizontally-spreading, hairy leaf stalks that are 1-5cm long. In the summer, slender, hairless stems up to 15cm tall emerge from the center of the leaf rosette, bearing small white to pink flowers with 5-6 petals. The roundleaf sundew is a well-studied member of the Drosera family and is often chosen for terrariums or bog-type gardens. It thrives in cooler regions, growing alongside moss and other bog plants, but does not tolerate temperatures above 85°F (29°C). As a carnivorous plant, it relies on a consistent diet of flies, bugs, or fish food. The roundleaf sundew blooms from spring to fall and enters a dormancy period during winter. Its impressive hunting mechanism involves using its sticky red tentacles to capture prey. Additionally, it produces small white-pink flowers.

If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly.

During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Roundleaf Sundew is always in the right place to thrive.
