@en2gen, you can find the entire plant database link at the top of any page in the menu bar where it says 'Plants DB'.
Once on that page, you can also find the Iris database under the 'Visit our plant-specific databases' and click on the Irises. Once on the Iris page, scroll down to find the search and browse box, you can type in any cultivar name, as you start typing, a drop-down menu will pop up with possible entries based on what you are typing.
You can also click on 'browse the full list of Iris' and see them alphabetically. Lots of thumbnails to see in the entire list!
Another tip; if you use the quote to reply to someone specific here, type your reply either before or after the quoted section, not between the [ quote ] and [ /quote] brackets. This way your text stands out separate from what you are quoting and doesn't get lost. I edited the two you did above so you can see how it should look.
