Salisbury var pubescens (Willdenow) [Cypripedium calceolus Linnaeus var. pubescens (Willdenow)] Large Yellow Lady's-slipper
|Location||Newfoundland, Nova Scotia, Prince Edward, New Brunswick, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, British Columbia, Yukon, Northwest Territories.|
The most common lady's-slipper and with the widest range of habitats. In every province in Canada, it can be found in boreal forest, bogs, open swamps and alongside streams.
|Flowering Season||May in the south to August in the north.|
The most variable of the yellow lady’s-slippers is difficult to describe as size and shape of the flower and plant are affected by location.
Keys to separating this species from the others are the size of the plant and flower, the colouration of the petals, the scent and the pubescence of the sheathing bract.
