Hello. I need some help in identifying this plant which is randomly growing in my yard. I live in Southwestern Ontario, Canada (Carolinian forest; plant hardiness zone 6a). The flower blooms in the evening and it only appears to bloom once. The plant is about 2-3 feet tall. The base of it is about as thick as a stem of broccoli. I have attached pictures of it.
Thanks for posting that. I've learned the word "vespertine" now (evening blooming), and can see how distinctly different it is from Brugmansia, some of which I think were still called Datura when I learned that name.
