Q.Under what conditions do morning glories bloom at night?
This will sound mystical and a little creepy, but when our cat died, who was beloved by the entire neighborhood, we buried him under his favorite bench in our garden. That night at 10pm I went outside to say goodnight one last time, and the morning glories covering our fence next to the bench were in full bloom. I called others to come and look because I thought I was nuts. I no longer recall if there was a full moon that night, but if there was, could that be the explanation?

Could you have the lavender moon vine? It will bloom at night but you would have noticed that before. I have seen some references that morning glories don't wait till morning to open, they open at dawn. Maybe like you said, a full moon inspired them to open sooner. Whatever the reason, it is very cool and otherworldly, plus I'm sure it was comforting. Just enjoy the story to tell.
