This is the vine I have growing on the light post this year.
If you remember I planted beans on it last year. I almost didn't plant anything, but then I thought of the moon flower seeds I had saved. They got a late start but they have been beautiful.
The only time I see them is early morning and early evening. During the day the flowers are closed. I have been told that they smell so good. I wouldn't know. I have lost most of my sense of smell.
