- Description
-
Roundleaf Sundew is a native carnivorous perennial found in boggy areas of mountains, or along coastal plain wetlands. It is found along the Little River in the sandhills and in the western mountains of North Carolina. It grows 2-10 inches high with a shallow root system. The round leaves generally are flat or nearly so to the ground and the flowering stalk uncurls to reveal small white 5-petaled blooms in summer.
The leaves have a sticky substance to which small prey adheres. Stalked glands near the edge of a leaf slowly bend inward, securing and placing an entrapped organism in the digestive area of stalkless glands. This allows the plant to grow in nutrient-poor areas.
This plant grows in acidic boggy areas in sun to partial shade. It can be grown in bog gardens and even terrariums but must be given a dormancy period. It does best in cool summer climates.
