Hi Joanna
I got the information from the Australian site. It will be Spring here in September . Did a quick google search as I am at work (2.30 pm 20/8) but this one came up.
The Daffodil is the first flower of spring, a symbol of hope, renewal, and for the American Cancer Society, the promise that one day the world will be free of cancer. Your participation in Daffodil Days will support the American Cancer Society's lifesaving research, prevention, early detection, and support programs.
