There was an article about Seville oranges in last Wednesday's Los
Angeles Times "Food" section. See
If you just want to buy the fruit, see
If you want to grow the plant, you live in the wrong area. Among
citrus, Seville oranges are relatively hardy. That means they are much
more hardy than limes, somewhat more hardy than sweet oranges, and
slightly less hardy than kumquats. They might grow in Sunset zone 8
where winter temperatures from 29F down to 13F, corresponding to USDA
zones 8 and 9. I suspect that they would not thrive at that lower
temperature (13F) since kumquats are hardy only down to 18F. In any
case, your winters in Pennsylvania (USDA zones 5 and 6) are too cold for
any citrus, with temperatures from 0F down to -20F.
If you want fruit, winter temperatures are important because many
seasonal citrus ripen in the late fall and early winter. Freezing
weather before or while fruit is ripening will damage the fruit and
might make it inedible (not toxic, just not useful).
Citrus does poorly as house plants and will generally not flower or bear
fruit indoors except in a climate-controlled greenhouse. Indoors, they
need 50% relative humidity and strong light through a window. Although
they must be kept from freezing, they must also be kept a good distance
from radiators, furnace registers, and other sources of heating.
Longwood Gardens in southern Pennsylvania has (or did have) an orangery
in its huge conservatory. You might inquire there about growing Seville

Thanks all -- I make jams and jellies and sell at the local farmer's
markets and I have had seveal requests for marmalade made from seville
oranges. I know I can't grow them here, but since I am only 15 miles
from Longwood gardens, who knows...
Thanks to all who took the time to reply
