The parents of a friend of mine used to have a bush that bloomed late afternoon and closed before morning. They often had gatherings about that time so they would have cocktails and be outside until dark. They called it a "cocktail bush", but that must have been a pet name as I can find no information on it. They lived in Crawfordsville, IN. Would you have any idea what kind of bush it could be?
Not exactly a bush but as the name implies it blooms in late afternoon. Depending on the zone, it can be an annual or perennial and is very shrublike. Here is a link to what the flowers look like: 4 O'Clock Flowers
