I've been making a list of where the daffodils shown came from (it's listed on each tag of each daffodil).
So far I've noted entries from Ohio, New Hampshire, Pa., Oregon, Indiana, Tennessee, Michigan, Ky., Wisconsin, Maryland, Washington DC, Washington state, Great Britain, New Zealand, and Missouri and Illinois.
(As I find more I'll just add to this list.)
Texas, W Va., Georgia, Arkansas, Va., Conn., Mississippi, Mass.
