English sundew

English sundew (Drosera anglica) is a perennial carnivorous plant belonging to the Droseraceae family. Unlike conventional crops, this plant has evolved to thrive in nutrient-poor wetland habitats, relying on specialized structures to capture insects to supplement its nutritional requirements, particularly nitrogen.

The species has a circumboreal distribution, native to northern temperate regions across Eurasia and North America. It predominantly grows in nutrient-deficient, acidic environments such as sphagnum bogs and peatlands. While not a conventional agricultural crop, it is of significant interest to botanical gardens and specialized plant nurseries.

Botanically, it features linear-lanceolate leaves arranged in a basal rosette, densely covered in glandular hairs. These hairs produce a sticky mucilage that acts as an adhesive trap for small insects. Once an insect is caught, the leaf surface engages in a slow digestive process, absorbing nutrients through its specialized glands.

Cultivation requirements are strict and strictly mimic natural bog conditions. The medium must be nutrient-free, typically consisting of pure sphagnum moss or a mixture of peat and perlite. A critical aspect of its care is the use of mineral-free water (distilled or rainwater), as dissolved minerals and fertilizers quickly cause root rot and physiological decline.

The species is primarily utilized for botanical research and as a specialty ornamental plant. Its extract is also noted in traditional medicine for treating respiratory issues, due to its anti-inflammatory properties. When cultivated, the plant is susceptible to fungal infections like Botrytis if airflow is insufficient or if the growing environment becomes stagnant.
