Multiple flower heads!
Since this area is on the south side it receives a lot of sun and dries out quickly. At the far side of the picture you can see I utilize a rain barrel. I plan on putting in a trough system to water the area this year and I'm planning on squash for 2015. The sunflowers were impressive, maxing out at 7 to 8 feet. However, I'm lucky I took these photos when I did because the next week they started to topple over from their own wieght.
