Maianthemum racemosum - False Solomon's Seal
Somewhat resembles the Great Solomon' Seal but the blooms on this are out on the tips of the stem. They are white and make a red berry in the fall. Will tolerate some sun in cooler climates but does best in shade. Once established they make a large clump and the red berries make quite a show.
Shade to Semi-Shade, Rich Soil, Spring, 1-3 ft Tall, Zones 3-8
