One warning with the Caesar weed...the seeds stick to anything that brushes against it, so be sure you deadhead quickly. And let us know if that works for you. Tasselweed is a favorite of mine in meadows, etc. The butterflies love it. I bought seeds for an improved variety one year, and it was gorgeous. The flowers were slightly larger and the most electric red-orange you can imagine. They sort of wove their way through the sunflowers and other plants like little red jewels. Now that I'm remembering them, I'm going to have to look for seeds again. Marcia (whose encyclopedia is missing quite a few volumes, believe me!)

Extremely interesting so I have hallucinogenic drugs growing beside my encore azaleas that's just great. It does appear to be a datura stramonium/jimson weed, which as Fata said is a member of solanaceae. Now the only question is, to remove it or to leave it and hope the deer eat it and "don't come back" to my yard...

It is Euphorbia maculata - Spotted spurge. Pull it right away.

Thank you! Wow, this everywhere on the United States map. Surprised I have never seen it before in my yard.
