I've never seen the unopened buds of a brugmansia before. Look like little okra pods. How cute! A fellow that used to live down the street from me had a white one in his front yard. It was about 10' tall I suspect. It was not potted so he lost it in a fluke freeze/ice storm in 2012. I have missed seeing it on my walks ever since.
The lady that used to live in my current house some 8 blocks away stopped by yesterday to pick up a piece of mail that came here for her. She said she was going to bring me a cutting off her yellow and pink brugs next time she came. Hope she remembers. I've always liked these plants.
