Many Pacific Coast iris hybrids are available that haven't been given a name. This is a subset of the nameless irises I've grown; these all have yellow, orange, or apricot flowers.
One of the first Pacifica irises I bought, and still one of the healthiest and most floriferous. One of the first to bloom each year.
