Joseph, I had no idea that morning glories opened at night...I thought it was only in the morning. And I had no idea that some have a fragrance!
My very first experience growing from seed was an annual morning glory I purchased. This was in 19xx...when we bought our first home in Oahu. I planted the seeds in a pot with a tomato cage for the vines to grow on. Every morning I looked forward to seeing the beautiful blooms. So morning glories are something of a sentimental thing for me.
And now, thanks to you, I will grow morning glories again. And I am happy we were able to do a seed exchange...adenium seeds for morning glory seeds.
