I have very few yellow spots in The Blue Garden, but this iris is a remnant from the previous owners. It grows under the huge sembra pine trees, and the first years we lived here only the greens of several irises came up. I was sure all irises were purple, and was surprised last year to see the first yellow flower. This year three of them are blooming, and I love their bright yellow in between all the red and blues.
Thanks Geum for teaching me that irises can also be yellow.
