Sorry this is a late comment, I haven't been checking in as frequently of late! Another wonderful resource for for information on warm/humid climate narcissus is the Florida Daffodil Society. They have a great website, test gardens in Tallahassee, and have published a very helpful book titled DAFFODILS IN FLORIDA: A Field Guide to the Coastal South ISBN-10: 0975921606 - ISBN-13: 978-0975921609 This is a link to the website http://profilingsolutions.com/FDS/FDS%20Home.htm/ They sell the book on their website, it is also available through Amazon 3rd party sellers, ebay, etc. Erin Grace
