With its alien looks, roundleaf sundew (Drosera rotundifolia) is the stuff of nightmares for insects. Hair-like tendrils on leaves are tipped with sugary, sticky droplets that unsuspecting insects mistake for nectar. Once a mosquito, fly or gnat zips in for a sweet sip, they’re trapped by the stickiness and the leaf slowly wraps around its prey, engulfing it and eventually consuming it. Look for varieties that are hardy in Zones 5 to 9.
Predatory plants hardy in temperate regions need a dormant period each year to thrive. Dormancy demands cool air that's above freezing (40 to 45 degrees works), like you’d find in an unheated porch or garage.
