Here's a handy link to Optimara's web pages. Some of us were lucky enough to go to the presentation at the 2006 National African Violet Convention in Minnesota given by the Holtkamp Greenhouses of Nashville, Tennessee. We got to hear first hand about the production and history of the Optimara violet. For everyone else this web site will be an enjoyable and educational resource to use not only when considering the Optimara violets, but anytime you're looking for information about your plants.
This link jumps to the middle of their site and gives you the complete glossary of violet terms. I started at the beginning with the letter "A", of course, but scroll to the 10th entry for example: African Violet, and you'll find a whole host of information with just that one entry. Try some more of the letters and there's an entire college course worth of material right at your fingertips.
The rest of their site is interesting and very well done too. After you're done looking at the glossary drop down to the bottom one of their pages and hit "Optimara Home Page" for the rest of your tour!
