Yellow.... Fall in the Yard

In the fall the Cassia Bicapsularis aka Winter Senna begin to bloom...  it is a sea of yellow in my front yard.   Along with that the Bolivian Marigold begins to bloom on the side of the house. The picture below shows the front garden with the tall Marigold on the side... notice it grows as tall as the roof line.

The first of the photos below is Cassia Bicapsularis, then a close up of the Marigold, and stepping back to see how it grows.  

 

The vibrant yellow of these flowers contrast with the pale yellow of another fall bloomer.  The Forsythia Sage....
