What are the morphological characteristics of this plant?
Drosera rotundifolia has a basal rosette of rounded, orbicular leaves that are typically one to several centimeters in diameter and covered in glandular tentacles. These leaves are characterized by long, slender petioles that attach the circular blades to a central stem. Each leaf surface is densely populated with bright red tentacles that secrete a sticky, glistening mucilage to trap insects. The plant also produces a single, upright flower stalk that emerges from the center of the rosette to hold small, pink or white flowers. Beneath the surface, the plant develops a short, creeping rhizome that allows it to spread slowly through its boggy habitat.
What is the geographical distribution of this plant?
This plant is native to the northern hemisphere, spanning much of North America, Europe, and northern Asia. It typically thrives in acidic, nutrient-poor environments such as bogs, fens, and moist peatlands. In North America, its range extends from the Arctic tundra down through much of Canada and the northeastern United States. European populations are widely distributed across temperate and subarctic regions, often favoring damp, open habitats. This widespread distribution is facilitated by its ability to survive in specialized niches where most other vegetation cannot compete.
How is this plant cultivated?
This plant requires constant moisture in a peat-based, sand-heavy medium and should be kept in full sun to partial shade while receiving only distilled or rainwater.
To mimic its natural bog habitat, the growing container must always sit in a shallow tray of pure water to prevent the soil from drying out. Maintaining high humidity levels around the foliage is essential for the development of the sticky, digestive mucilage on its leaves. It thrives best in cool to temperate climates where it can undergo a necessary dormancy period during the winter months.
Proper airflow and consistent hydration are the most critical factors for preventing fungal issues and ensuring successful long-term growth.
What parts of this plant are used medicinally?
This plant Drosera rotundifolia is used medicinally through its specialized leaves and the glandular tentacles that cover them. These tentacles secrete a sticky mucilage containing various bioactive compounds that are harvested for therapeutic use. The combination of the leaf surface and the digestive enzymes within the tentacles provides the essential chemical properties required for treatment. Practitioners typically utilize these parts to create tinctures or extracts aimed at treating respiratory ailments. This specific botanical combination is valued for its ability to act as an expectorant in traditional herbal medicine.
According to a study published by "Advances in experimental medicine and biology", Drosera rotundifolia L. has a circumboreal distribution. This plant inhabits nutrient-poor, moist and sunny areas such as peat bogs and wetlands. The leaves are collected from the wild-type for various medicinal preparations. These leaves can be utilized in treating respiratory diseases as an important cough-medicine. The antimicrobial activity of extracts from the aerial parts against various bacteria has also been investigated. Among the various secondary metabolites produced by the plant, the most abundant are the naphthoquinones.

According to a study published by "Analytical and bioanalytical chemistry", Droserae herba is a drug commonly used for the treatment of convulsive or whooping cough since the seventeenth century. The therapeutic activity of Droserae herba is attributed to the contribution of flavonoids and ellagic acid derivatives. Through the development of an LC-DAD method, 13 compounds were detected and identified in four Drosera species, including D. rotundifolia. In D. rotundifolia, the most prominent component was identified as 2″-O-galloylhyperoside. This component, along with myricetin-3-O-β-glucopyranoside and kaempferol-3-O-(2″-O-galloyl)-β-galactopyranoside, was identified for the very first time in this genus.
