Four O'clocks

A number of years ago, a friend gave me a Four O'clock in a flower pot. It bloomed profusely, and as the blooms died, they fell to the ground. Soon, there were Four O'clocks growing all around the pot. They continued to grow and spread until they covered enough space to be really showy. I am posting one photo to show you the blossoms close up and another to give you an idea of how they have spread. The plants are taller than I, and I am 5'7". I think they are beautiful , though DB thinks they harbor mosquitoes. They probably do!
