Ben-The database here at ATP shows 10 cultivars for you. Restless Tide is one of the 10. So is Love Dart. I did not notice it before, but the database does show that Love Dart was registered but not introduced. I missed that piece. So the database is missing Storybook Princess.
How did I get there?
Click on the "Plant Database" tab in the top left hand corner.
Click on the list on the top right and scroll down until you get to the Iris database. Click it.
In the left center top of the page you have three options:
"Browse by full options"
"Search by Characteristics"
"Access the genetic iris entry"
Click the middle one (Search by Chac.)
Fill in the hybridizer box ("Ben Johnson") and then click search.
10 items displayed in alphabetical order. You can now click on the picture and you are taken to the page of that plant. You get plant data and any pictures submitted by users.
