i have ..not very often .. tricked a z6 into living over winter for a year or two ... in a perfect micro climate ...

i highly doubt you will have any luck tricking mother nature into 2 or 3 zones ...

google propagation of such.. and see if you cant take a couple small pieces off the side.. rather than digging up a huge plant ...

in other words.. try to over winter it.. but cut your odds....

in the alternative... you are basically going to have to pay the bucks.. and grow a perennial as an annual ... of which.. many of our annuals actually are ...

Ken,

I appreciate the advice of taking some, rather than, all of it from the yard. I hadn't thought of it. I really didn't expect it to grow so much in 2.5 months.
