I've also got a book by British beekeeper Owen Myer with a fairly detailed
list of nectar plants.  Most of it is valid here in the Northeast U.S. as
well, although the dates are a bit off.  Some that are listed as minor flows
are quite major here (like goldenrod) and vice versa.   * denotes pollen
source only.


Happy reading,


Todd.
