just a warning to you, Cat......Jerusalem artichokes are sunflower-like
plants and here in Eastern Tennessee, they get HUGE! advice? (excuse
my being forward) give them plenty of room..........

They get tall (6ft or so), but don't seem to need much sideways space -
about what you'd give to potatoes. They might flower but don't always do
so. And once you have them, they're quite hard to eradicate. But easy
and trouble free - well worth growing.
