hi, yes, i've overwintered them from plants started from johnny's seed- 
imperial star.  i dug them up, left the soil loosely around the roots, 
and wrapped them in wet newspaper.  i kept them in my root cellar and 
then planted them in the hoophouse in march.  they made several 
artichokes, though they were admittedly smaller than the previous 
years.  it was just something to do; i don't think it's that profitable.
