The mountain lady's slipper ( Cypripedium montanum ) is a species of the genus Cypripedium in the orchid family (Orchidaceae).
description
The mountain lady's slipper is a perennial plant with a rhizome that reaches heights of 25 to 70 centimeters. The stem has four to six leaves . These are variably shaped: almost round, elliptical, egg-shaped to broadly lanceolate. In sunny locations, the leaves are crowded in the lower area of the stem and point upwards, in shady places they are more distributed on the stem and splayed to the side. The length is 4 to 17 centimeters, the width 3 to 8 centimeters. There are usually one or two, rarely three flowers. The outer and inner tepals are heavily reddish-brown on a green background, rarely pure green. The outer tepals are much longer than the lip. The upper outer tepal is 3 to 6.5 inches long. The inner tepals are twisted, 4.5 to 7 inches long and only 3 to 5 millimeters wide. The lip is white, the opening measures 13 to 22 millimeters and tapers at the front. The staminodium is diamond-shaped to broadly oval.
The flowering period varies in the large area from Alaska to California from February to September.
Occurrence
The mountain lady's slipper occurs in warm to cool western North America in fresh to dry, rarely in humid open forests, swamps, oak bushes and on subalpine slopes at altitudes of up to 2400 meters. The distribution area extends from Alaska to California.
use
The mountain lady's slipper is rarely used as an ornamental plant for groups of trees.
