Cat said:Can you help? I just purchased "Somewhat Elegant" and "Mystic Image" from the LA. 
The confusion is with Mystic Image. The LA listing, the AHS data base and ATP listing all say (Pierce-G., 2010). I found it listed on Floyd Cove as (Pierce-G., 2011) and one other site as (Stamile 11). The AHS, ATP listings are correct, correct? 
I would say the others are just typo's...What do ya think?
The difference in the year is when it was registered and when it was introduced. Most hybridizers submit their registration before the Oct deadline so it will get added to the checklist (and the info available in the AHS database) when it is updated in May. Anything submitted before the October deadline will have a registration year usually one year before the introduction date (unless it is a fall introduction). Example is what you have 2010 registration but 2011 introduction year on hybridizer's website. Hybridizer's use the introduction year on their websites.
Also the difference in hybridizer names is that Stamile used to own Floyd Cove nursery and sold it to Guy Pierce so some of their intros will be under Pierce-G while others will have Stamile (because it was one of his) or it may be Stamile-Pierce.
