Large yellow lady’s slipper (Cypripedium parviflorum var. pubescens), also called greater yellow lady’s slipper, is found throughout Minnesota except for the southwest corner of the state. In most of the state it occurs in moderate or deep shade in moderately moist upland forests. In the northwest corner of the state it occurs in full or partial sunlight in wet prairies and sedge meadows. The large showy flowers appear from May 10 to July 10, with peak blooming time June 5 to June 20 in the north and May 20 to June 1 in the south. Do not touch. The hairs on the stems and leaves cause dermatitis in some people.
