This picture is from August 17th. Since then, one of the sunflowers has fallen over. Those flower heads are getting heavy with seeds. You can see the white seeds on the ground that have been falling from the flowers. I haven't noticed any birds eating them. The seeds may be too immature yet.
The pumpkin plants now have blossoms and are sending out runners. The gardener for this apartment complex was around last week and adjusted the lawn sprinklers to add 5 extra minutes to the watering cycle. You can see that the ground under the plants is a darker color than the ground on the right of the photo. That moister ground is the over-spray from the lawn sprinklers. That's how I keep the pumpkins watered and the reason lazy Uncle Ernie planted them there.
