I was in Sacramento over the weekend and saw two plants in street plantings throughout the old part of the city. I'm hoping someone here can help me identify them.
The first looked very much like a Japanese Iris, although it grew in clumps, rather than individually. The blossom was pure white, with a yellow streak in the throat, and a smaller purple streak on the top of the cup. The foliage was long slender blades.
The second had similar foliage, but the white blossom was flat, with three almost round petals.
Both were quite tall -- 30" or higher.
Anyone have any idea what they could be?
