We have this tree growing in our yard. It emits a strong bad smell around 11pm at night. During daylight hours it has a light citronella-like smell. The night smell is awful.
Are you sure its not a tree covered in this plant? The plant looks like a passiflora sp.
I agree. What I'm seeing is the Passiflora vine covering a tree.
I agree as well; if you could get a clear picture of an open flower, I might be able to give the species - only a few flower at night.
Thank you everyone for your help. It is a passiflora variety that had taken over two trees when we started untangling it. When it blooms again, I'll start a new thread to see if we can identify the species.
