Maianthemum dilatatum
(Two-leaved Solomon's Seal or False Lily of the Valley) is a common rhizomatous perennial flowering plant in the Ruscaceae Butcher's Broom) family. It is native to western North America from northern California to the Aleutian islands, and Asia across the Kamchatka Peninsula, Japan, and Korea. It grows in coastal temperate rainforests, and is often the dominant groundcover plant in Sitka Spruce forests. The plant produces an erect, unbranched stem up to about 40 centimeters tall. A non-flowering shoot bears one smooth, waxy, shiny leaf up to 10 centimeters long and 5 to 8 broad, hence its scientific name (dilatatum means 'broad'). On plants that are flowering, 2 or 3 leaves are produced oppositely on the stems. The leaf is oval in shape with a heart-shaped base. Although it can be a vigorous spreader where conditions are right (shady and damp), it makes a good groundcover for shady northern gardens.
