I first saw these beauties at the Reader Rock Garden. The large yellow lady slipper orchid is actually native to all provinces in Canada. This perennial terrestrial orchid is most commonly found in moist forests across the region. This plant prefers a semi-shaded site that is cool and not exposed to hot mid-day sun. Conditions suitable for ferns are suitable for hardy orchids. An organic mulch will assist the plant in maintaining moisture and keeping the roots cool.
Here's a photo taken at Weaselhead Park in Calgary:
Here's my own personal Queen's lady's slipper orchid. I plan on adding additional plants to my garden next year.
