This colorful cascade of color decorates my driveway and gives pleasure every day.  It is very unusual for bouganvilla to grow down a wall like this.  These plants were trained when they were young and supple.  A string weighted with a rock hanging over the wall trained the branches to bend downward.  The neighbors laughed at my dangling rocks but it has paid off.  Some of these plants ar two colors with magenta and white blossoms on the same plant.  A natural bouquet.
