Hooker’s Thistle – Native Plant of the Day 01/08/2017
Photo from 6/21/2011. Location: Boise Foothills, Ada County, ID.

NOTE: A comment (below) from Bruce Bennett put my 5-year-old identification of this plant as Cirsium hookerianum in question. While I haven’t yet had time to research my reason for discounting other white-flowered thistles, some quick research on Bruce Bennett’s credentials implies that he can speak with some authority pertaining to plants in the area, making his identification of this plant as Cirsium undulatum (Wavy-leaf Thistle) almost certainly correct. Thank you, Bruce!

I love thistles!
Cindy and I do too, Mia. I was especially glad to find that this one we see on our trips to Idaho is a native plant. Thanks for the visit and comment.
Seen in Alberta near Ha Ling peak!
the photo is of Cirsium undulatum not C. hookerianum
You may be correct, Bruce. To help me research it, what specific attributes lead you to that conclusion?
Thanks.
