About plant names...

White lady's slipper is an increasingly rare native of North America. Please don't pick them or try to transplant them!

Identification: These small, rare, delicate plants are 4-14″ (10-35 cm) tall, with 2-4 roughly oval-shaped leaves 1¾-6″ (5-15 cm) long. Each stem supports a single white slipper-shaped flower, sometimes with purple markings, 1-4″ (3-11 cm) long. They do not grow in acid soils, but prefer alkaline bogs and fens or meadows, such as those near limestone.
