Deeply Rooted
I doubt you need a piece of the crown attached, as the whole *reason* it's so hard (ok, impossible) to eradicate from the garden is that it will come back from small pieces of root left in the ground, a la thistle or quackgrass.
If it were me, and I couldn't find a storeboughten piece with crown, I'd just take the best-looking rootiest plumpest piece I could get, whack it into sections a few inches long, then pot them up so I could easily see whether anything was sprouting. Once I had a piece or two that was clearly growing, it could go into the ground. (You *could* put them in the ground in the first place, but unless you have remarkably weedfree soil it will be harder to tell what's goin' on)
Good luck, have fun, be careful it really DOES run everywhere,
