Beautiful, Alex! These are Datura " Devil's Trumpet". They do grow very FAST AND RESEED PROLIFICALLY. Pick off the thorny round pods and just let a few mature. You will have more than enough seed for next year. :)

Sorry, arctictropical! I called you Alex....:) Mixing up the "tropicals" lol

Wow, beautiful Daturas! Brugmansias and Daturas are so fast growing! Mine grew really fast and I saw some out on Long Island today that were 7 feet tall and had tons of blooms!
And, lol, I get confused with some of the similar user names too theras!

Theresa, no problem! Thanks Alex. Whatever they're called, they are certainly beautiful.

I find that they do like cool weather

your plants are just fantastic

Thanks, Diane. They are kind of sad looking now. They grew out of control so much, that I think they simply got tired of growing. I got tired of picking the old faded flowers off because there were so many, so I quit.
