About
This widely distributed sundew is notable for its ability to thrive in poor, wet, and acidic habitats, forming a semi-erect rosette of spatulate leaves. It is a perennial herb that forms a winter resting bud (hibernaculum) in temperate regions.
Field notes
Morphology
It forms a semi-erect stemless rosette of spatulate leaves up to 10 cm tall. The plant produces inflorescences up to 15 cm tall, bearing 3–8 white flowers.
Distribution & habitat
Native to Europe, eastern North America, Cuba, and northern South America. The Cuban and South American forms are tropical.
Ecology
The leaf blades are covered with stalked mucilaginous glands that secrete sugary nectar to attract insects. These prey are ensnared by the mucilage and suffocated or die from exhaustion, after which the plant absorbs digestive enzymes to supplement poor mineral nutrition.
