Drosera rotundifolia

Updated: 2026-07-15

Overview

Drosera rotundifolia, commonly known as the round-leaved sundew, is a fascinating carnivorous plant native to bogs and wetlands across Europe, Asia, and North America. It thrives in nutrient-poor environments, supplementing its diet by trapping and digesting insects. The plant's leaves are covered in red, glandular hairs that secrete a sticky mucilage, which ensnares prey. This species is prized not only for its ecological role but also for its medicinal properties. Traditional herbal remedies have utilized sundew extracts for respiratory ailments, though modern applications require further research. Its unique appearance and insect-trapping mechanism make it a popular choice among carnivorous plant enthusiasts.

Key Features

The round-leaved sundew is easily recognizable by its small, round leaves, which are densely covered in red, sticky tentacles. These tentacles glisten in sunlight, attracting insects. Once an insect is trapped, the leaf slowly curls around the prey, secreting digestive enzymes to absorb nutrients. The plant typically grows in acidic, waterlogged soils, often in sphagnum moss bogs. It produces small white or pink flowers on tall stems, which bloom in summer. Unlike many other plants, Drosera rotundifolia has adapted to low-nutrient environments by evolving its carnivorous feeding strategy.

Application Areas

Drosera rotundifolia has several applications, ranging from ecological studies to traditional medicine. In herbal medicine, it has been used to treat coughs and respiratory conditions, though scientific validation of these uses is limited. The plant's extract contains compounds like plumbagin, which have shown antimicrobial properties in preliminary studies. Ecologically, the sundew plays a role in controlling insect populations in its habitat. It is also a popular ornamental plant among carnivorous plant collectors, often grown in terrariums or bog gardens. Conservation efforts are important, as habitat destruction threatens wild populations.

Precautions

When handling Drosera rotundifolia, care should be taken to avoid damaging its delicate leaves and tentacles. The sticky mucilage can be irritating to skin, so gloves are recommended during transplantation or maintenance. The plant requires specific growing conditions, including high humidity, acidic soil, and plenty of sunlight. Overwatering or using tap water can harm the plant due to mineral buildup. Distilled or rainwater is ideal for irrigation. Additionally, avoid fertilizing, as the plant obtains nutrients from captured insects. Pests like aphids can occasionally infest sundews, requiring prompt removal to prevent damage.

B2B Procurement Guide

For businesses sourcing Drosera rotundifolia, it is essential to partner with reputable suppliers specializing in carnivorous plants. Look for nurseries that cultivate plants sustainably, avoiding wild harvesting to protect natural populations. Bulk purchases may be available at discounted rates, but ensure plants are healthy and disease-free. Shipping requires careful packaging to prevent damage to the fragile leaves. Live plants should be shipped in moist sphagnum moss or similar media to maintain humidity. Pricing varies based on plant size and rarity, with wholesale options often available for larger orders. Certifications for organic or sustainably grown plants can add value for eco-conscious buyers.
