Identify This Plant Please
It comes up in spring from a corm, I believe. The plant is a single stem, about 24 inches tall, with about 8 to 12 flowers that raise up in the evening and drop down in the day time. I had about 5 plants some time ago but have accidentally dug them out. Color was light purple to blue.
The plant is possibly "Four O'Clocks" or Marabilis Jalapa. This article should help: http://www.gardensablaze.com/Perennials/Perennials4oclock.htm
