The delicate Calypso Orchid, also called Fairy Slipper or Venus Slipper, is a beautiful wildflower with a growing season from mid-May to early June.  Of course, this timing is dependent on when the snow leaves the ground.

Where to find them

You will find clusters of these beautiful flowers in the Lodgepole pine needles that blanket the Montane forest floor.  They prefer shady locations, and the canopy of the Lodgepole pine trees provides that.  I saw these particular orchids along the Spray River Loop in Banff National Park.

Deceptive yet clever pollination strategy


These flowers are beautiful and are very smart when it comes to their pollination strategy. They have a slight vanilla smell to them, and their beauty and vibrant colour attract the bees to them.

The bee, anticipating a  sweet reward, crawls into the orchid and soon discovers that there isn’t any nectar and moves onto the next orchid but is again disappointed. In the meantime, the Calypso Orchid’s strategy has been working, as the bee has been gathering and dispersing pollen to the other orchids. After several failed attempts to get nectar, the bee moves to a different species of flower.

Native uses

The Nlaka’pamux, previously known as the Thompson River Indians,  used the plant to treat mild epilepsy. They would chew the bulb or suck on the flowers to help reduce seizures. Other Native groups used these tiny bulbs as a food source. ( source: Mountain

A fungus is their Friend

Calypso orchid seeds do not provide a lot of nutrients for the plant. To assist with this lack of nutrients, the Orchids have developed a mutually beneficial relationship, also called a Symbiotic relationship, with the Mycorrhizae (“Mycor” –“rhiza”) fungus.

The Mycorrhizae. Com website explains this relationship best:

“Mycor” – “rhiza” literally means “fungus” – “root” and describes the mutually beneficial relationship between the plant and root fungus. These specialized fungi colonize plant roots and extend far into the soil. Mycorrhizal fungal filaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than the roots themselves. More than 90 percent of plant species in natural areas form a symbiotic relationship with the beneficial mycorrhizal fungi.”

Take a hike soon and take only pictures

Their growing season is from mid-May to early June. They are beautiful, and it would be very tempting to pick just one….however….it is illegal to pick any wildflowers, so please take a picture -take many!

Happy Hiking!
