Additional Notes about Large Yellow Lady's Slipper:


Native to Ontario and much of North America.

The fragrant flowers attract a range of insects and utilize a clever mechanism to ensure pollination: there's only one way out of the flower, and the insects cannot help but collect pollen at the exit. However, despite producing up to 50,000 seeds per pod, due to declining habitat, this orchid is endangered.
