Here in PEI, we see red pollen from maple tree flowers, which emerge
about the same time as pussy willow is over.  That will not be for a few
weeks yet here, but the color is quite startling, when yellow pollen is
the  usual that we see.  Pussy Willow, Alder, Maple, Dandelion, seem to
be the order for pollen in early spring in the Maritimes.  As yet we are
just beginning to see crocus, which incidentally are excellent for
pollen too.
