We North Americans in the lands commonly referred to as either
Midwest (grumble) or Great Lakes tend to think of pines as something of a
northern tree, at least those of us in the middle latitudes between the
lands of cold and warm. Indeed, west of the Appalachians and east of
the Rockies, native pines are largely missing from the landscape south
of the Great Lakes, throughout most of the prairies, and until one gets
into at least the edge of the South. The same is not true for the
coasts of the continent, where pines can be found from the Arctic
treeline down well into the tropics. Many botanists, in fact, will
point out that the greatest living diversity of pines and probable place
of origin for many ice-age surviving species is in Mexico, hardly
northern by most standards. Some pines, in fact, only like areas that
are warm most of the year if not outright hot and dry. Only one species
of pine, the noble and scraggly Jack Pine (Pinus Banksiana), even makes it to the northern limit of trees.
Still,
where once central North America used to have a relative dearth of
things pine, one is likely to run across some thanks to a modern
landscaping fetish for durable, mass-produced coniferous evergreens.
Sometimes this results in lovely drifting plantings of the majestic and
sacred Eastern White Pine (Pinus Strobus) which seems to be
popular well into Nebraska and southwards wherever the climate will be
merciful. More often than not, however, the Austrian, or Black Pine (Pinus Nigra)
gets slammed into tight groupings to serve as an exotic windbreak far
from its happy mountain home in the northern Mediterranean higher
elevations. This is a shame, because we have so many wonderful pines
available for use here that can take hot summers rather well. Anyway, I
digress. How about those hot summers?
