jimsonweed, Datura stramonium

Last week I drove by a field with a lot of jimson. Jimsonweed flowers are only fully open at night. They're three to four inches long. Very attractive, for a poisonous noxious weed. Night before last I happened to wake up at 4 o'clock. Laying there, these flowers came to mind. So I headed out to see jimsonweed in its full glory. Guess what? Wildflowers are hard to find in the dark. And I didn't remember the spot as well as I thought. So, another day trip to check, and this shot was from 11:30 last night. I hope this is fully open, because three trips is enough. These flowers are sometimes purple. This arrival from tropical America has now been seen in every state except AK and WY, and in AB, BC, MB, NB, NS, ON, PE, QC, and SK. Lenawee Co MI, 9/4/19.
