Overview
Small, insectivorous bog plants, Sundews trap and digest insects. Several species grow throughout the United States, capturing their prey in sticky, hairlike leaf structures. Bogs are nutrient-poor environments, and the plants obtain nutrients from their insect diet.
Structure
Glandular leaf hairs secrete a sticky substance that attracts small insects. When triggered, the leaves enfold the prey. Secreted enzymes digest the insect, and the plant ingests the nutrients through its leaves.
Diet
Sundews eat flies, midges and fruit flies. Larger species may dine on spiders, mosquitoes and butterflies.
Growth Habit
Low-growing sundews range from 1 to 8 inches in height. Flowers appear on slender 12-inch stalks.
Requirements
Hardy to zone 3, sundews grow best in full sun but tolerate full shade. They prefer wet, peaty, acidic soil with a pH between 4.0 to 5.0.
Habitat
Sundews are widely distributed. They grow in bogs, swamps and stream or pond perimeters. Species are found all over the U.S. as well as Greenland, Europe, Asia, South Africa and South America.
