RE: cypress and such - again

I suspect that it is an uphill battle to convince most
people that Acacia trees and shrubs are not the source
of their allergies, and for most people, who have not
been specifically tested for allergic reactions to
specific allergens, they will believe what they want
to believe.  It does seem to be common sense that many
conifers, which dump quantities of pollen at the same
season as many of our more common Acacia trees, are a
more likely suspect.  Grasses are also prime suspects,
being wind pollinated and releasing quantities of
pollen in late spring/early summer are always what
trigger my worst hay fever attacks.

As to the original post about plants for dry locations
under Cypress trees, it might be worthwhile to note
that the trees themselves act as a barrier to rain,
and the intense root competition at the base of such
trees does make it difficult for normally drought
tolerant plants to survive the extra competition for
soil moisture.  Also, the extreme winter lows as noted
would seem to exclude some of the more tender plants
suggested.  In my experience, the Ceanothus griseus
cultivars will not take either that degree of cold or
drought.  As I am not accustomed to designing for such
cold locations, I will refrain from specific
suggestions, but would think that local examples of
plantings that work would be your best lead...
