I often walk past this swamp area behind the mall and I sometimes take photos of the long, dark green "grass". It looks good when the sunlight hit it the right way.
Today the "grass" had lots of yellow flowers. Something I'd never seen before. Turns out it wasn't grass at all, it was lots of yellow irises.
It is hard to get a decent shot from here. Lots of trees and foliage partly blocking the view of the irises and the mall and another, ugly office building behind the irises.
