To find the iris Database that Kent referenced, click the Plant DB in the menu bar at the top then click the blue "View our plant-specific databases". On that page is a list of specific plants, including Iris. When using the Iris database search box, once you start typing in a cultivar name, it will start popping up suggested plants based on what you type. As soo as I entered the word 'And', it's the first one that pops up.
