There is a strip between the sidewalk and fence along my south fence that
I'd like to fill with herbs, etc., that spread and "take over" so that
it's so dense that weeds, grass, etc. will feel unwelcome and not be a
problem. The strip is about 12 inches wide (and 135 feet long).

I planted a couple of chocolate mint plants last summer which survived our
colder-than-usual winter. All suggestions are welcome as to what to use
there. It would be ideal if watering was minimal to keep from stretching
a soaker hose out there. There is a concrete rail under the fence so the
plants would be backed by concrete which means there would be extra warmth
for both growing and need of more than usual water (or it could act as a
plus for less water?).

Suggestions, folks?
