I grow the basil in pots and bring it in on nights when a freeze is
expected. You can have it and impatiens as a perennial if you do that
for the 4-5 nights a freeze is expected here normally.

The dill will freeze and die. The most varieties of oregano (aka: sweet
marjoram) will survive a freeze as will lemon balm and spring back in
the spring. Cuban oregano (fleshy, fuzzy leaves) needs to be in a pot
and brought in.

If I had some nice purple basil babies coming up, I would put them in
little pots and leave them in the sun and then bring them in when
freezing temps are expected, and then put them back out. By next spring
you will have nice sized basil bushes in pots!

I do this a lot and keep things going longer than can normally be
expected sometimes for a couple of years until I forget one night to get
them all in before a freeze. Believe or not my Baby Arlesa French
zucchini is making babies now and I have it growing in a pot. It has
not even contracted squash borers -- a miracle! So I will tote it in and
back out as well.

The basil really won't grow at all once it is cold out. So I
just let them die when it gets cold. A little covering can keep
them around another month or so but they will grow slowly if
cool out. You could just harvest it all and make pesto or
something and preserve it like that. That is what I am going to
do this week.

What about other herbs? I have thyme, oregano, mint, lemon balm,
rosemary, and dill. Will any of them survive the winter?
