Description of Plant(s) and Culture

Adder's tongue is a perennial plant to 1 foot high; its bulbous root is light brown on the outside and white inside. It grows two leathery, basal, lanceolate, pale green, mottled leaves with purplish or brownish spots; and one drooping, miniature, lily-like, yellow flower, petals strongly curved back, nodding from the top of a central stem, appears in April or May. The narrow spike somewhat resembling a snake's tongue gave the plant the common name of adder's tongue. The petals partially close at night and on cloudy days; the plant diminishes with the heat of summer. The fruit is a capsule.
