Description of Plant(s) and Culture

Sundew is an insectivorous (insect eating) perennial plant; the root produces a basal rosette of nearly round, reddish, glandular-hairy, tiny, leaves 1/2 inch across, mostly wider than long, which exude a liquid (dewdrops) that traps insects. The leaves fold over the captured insect and digest it. Naked flower stalks, from 2-12 inches high, are topped by one-sided racemes of small, white or pinkish (sometimes red) flowers which bloom from June to August.

Blossoms open one at a time.

Legends, Myths and Stories

Sundew is a carnivorous plant with ninety species of the Drosera genus throughout the world. Digestive juices, analogous to pepsin, are excreted, and the insect is dissolved and absorbed. Sundew is the smallest of the insect eating plants, it is about the size of a silver dollar. The Venus fly trap is of this family; its leaves are two-hinged blades, with sensitive hairs, that close when touched, thus entrapping the insect.

Uses

Historically, herbalists employed this plant for respiratory and chest complaints, including coughs, asthma, catarrh, and bronchitis. Practitioners also administered it for nausea, upset stomach, and arteriosclerosis. In European folk traditions, the fresh juice was applied to warts and corns, and taken internally as an aphrodisiac, while the plant was additionally utilized in cheese-making to curdle milk.

Within homeopathic practice, it was prescribed for conditions such as headaches, laryngitis, nausea, and sciatica.
