Jimson Weed

I was lucky enough to see this plant on an acreage near Millarville (south of Calgary) last year.

"Datura stramonium is also known by the common names jimson weed, ditch weed, stink weed, loco weed, Korean morning glory, Jamestown weed, thorn apple, angel's trumpet, devil's trumpet, devil's snare, devil's seed, mad hatter, crazy tea, malpitte,and "poor man's acid". It is a common weed in the Nightshade Family. It contains tropane alkaloids that are sometimes used as a hallucinogen. The active ingredients are atropine, hyoscyamine and scopolamine which are classified as deliriants, or anticholinergics. Due to the elevated risk of overdose in uninformed users, many hospitalizations, and some deaths, are reported from recreational use." From Wikipedia.
