Under what conditions do morning glories bloom at night?

Question

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?

Answer 1

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.
