This very helpful presentation was compiled by the ADS Historic Daffodils Committee,and produced by ADS member, Paul Botting, of Maryland in 2011. An excellent educational resource for ADS Accredited Judges, so you will be well informed on judging historics.
Can be used as an ADS judges refresher course if an Accredited Judge Instructor (AJI) conducts the discussion session. For those that aspire to win with in shows with older daffodils, this program will help.
This presentation is also available as a free download at the American Daffodil Society's website: dafftube.org. Please consider your Internet connection speed, and other variables, if you wish to avail yourself of the free download opportunity.
