Thistles can be found in many areas in Southern Quebec.  They typically grow naturally in fields.  They are in full bloom near the end of the summer.
The Elk Thistle (Cirsium eatonii) is a thistle native to Jackson Hole in Wyoming. As its name implies, elk feed on this plant. It is also called Everts Thistle after Truman Everts, a member of the 1870 Washburn–Langford–Doane Expedition, who explored the area that later became Yellowstone National Park.  Everts became lost and survived for a month by eating the elk thistle.  This elk thistle in bloom was photographed at Oxbow Bend in Grand Teton National Park near Jackson, Wyoming, USA.
