How to identify California pitcher plant (Darlingtonia californica)

California pitcher plant, also known as Calf's head

California pitcher plant displays a distinct carnivorous adaptation with its tubular leaves that can reach lengths of up to 3 feet (91 cm). These hollow, green to reddish pitchers have a bulbous, translucent hood, which exudes nectar to lure prey. The hood's underside is slick and contains light windows to confuse entrapped insects. Trapped prey is prevented from escaping by downward-pointing hairs and is subsequently decomposed in the contained liquid for nutrient absorption.
