Re: weather

One other interesting thing in Bailey. It says the opuntia is a more important food crop worldwide than many of the horticulturally recognized food crops.

Bailey [Cyclopedia of Horticulture, 1942] says there are about 130 species and untold numbers of naturally occurring cultivars and hybrids. Also says it has become an invasive menace nearly everywhere where it is not native [mostly Australia and Africa].

Cacti are found from Canada to Patagonia, and in every state in the
Continental US except Maine, New Hampshire and Vermont. (I personally
saw a cactus ?Mammilaria sp. growing in the wild in Southern Minnesota.)

At the National Academy of Sciences building in WDC, there is an
opuntia that was brought back from the top of the Andes by some
scientific expedition or another. Gotta be close to perennially
cold up there. I've got no idea what the species is, but one of its
interesting attributes is that it is a prostrate grower, no more
than about 6 inches high.

Judy, some opuntias are winter-hardy.  I know several stands here in
the Hudson Valley, most notably a large patch that grow on a rocky
outcrop above the river.  Unlike this strange winter, most years the
temperatures are well below freezing most of the winter, and
sometimes fall below zero.  I think this species is Opuntia tuna,
but there has been some question about it.  I have seen another
species in a garden in Chincoteague, Virginia, where the temperatures 
are milder than here, but still a lot of freezing weather.  These
are much
larger than the local ones, but seem totally hardy.

I think the cacti here are opuntia. Mine looked dead after we went
from 70s
to -10F overnight one fall. Everything was flat dessicated, looked
like a
total loss, but it came back. Lost about half its bulk, but I was
surprized
how much of the part that looked freeze-dried, survived.
