Ram's Head Lady's Slipper
|Location||Nova Scotia, Quebec, Ontario, Manitoba, and Saskatchewan. In Ontario, mainly a Great Lakes - St. Lawrence orchid of the Mixed Forest Region.|
Two different types of habitat: one dry to moist, the other moist to wet. The first is provided by maturing coniferous forests in areas of thin soil or sand dunes over flat-lying calcareous rocks. Plants grow in dappled to partial shade of openings in the forest canopy.
|Flowering Season||Last 10 days of May to mid. June.|
Height 10-50 cm. Stem slender and hairy.
Blooms a little ahead of other Cypripediums in areas where it occurs. Most common on Bruce Peninsula and Manitoulin Island in Ontario. Some locations in the Bruce Peninsula and Ottawa District are known to have provided stable habitats for this genus for many decades. Plants develop rapidly after appearing above ground, and blossom is rather short-lived. Pollination of a bloom creates a hormone reaction within an hour, causing the upper sepal to drop down and seal the lip. Requires cool soil conditions.
